XF 200 jets?

[09Fx200Q]

O.k. I'm ordering the pro circuit t-4 system that Trevort recommended today.

http://www.ebay.com/itm/231175131958?ssPageName=STRK:MEWAX:IT&_trksid=p3984.m1423.l2649

Also ordering a moose racing air filter.

http://www.ebay.com/itm/MOOSE-RACING-AIR-FILTER-SUZUKI-DR-200-DR200-1999-2009-/291177847679?pt=Motorcycles_Parts_Accessories&hash=item43cb8d5b7f&vxp=mtr

I was going to go with a k&n 50mm cone, but it seems from what I've read that the bs carbs don't like not having an air box so I figure I won't mess with that...

I'm still unsure on what jets to order? I've read that most ppl have changed to the 35 genuine mikuni main jet and I'm unsure if I need to change the needle too? Could use some help on this. Links for the right jets needles and advice please. Thank you:yay:

[trevort]

Forget Ebay for jets and goto Jetsrus.com look for Mikuni Bs Carburetor jets. Order a few different sizes like: Main 127.5, 130, 132.5 and the smooth side pilot jets 35, 37.5 the non-Mikuni jets work just fine as the o.e. ones. As for running a k&n pod style airfilter: I run one of these on my bike and have no probelm with a lack of back pressure due to not having an airbox and also no popping or back firing on acceleration on under engine braking. I am currentlny running a 142.5 main 37.5 pilot needle in the 3rd clip position and one turn out on the air screw, get you a sharpe paint pen and write your carburetor settings on the float bowl as a reminder in case you forget later what you have done jetting wise.

p.s. please post pics of your bike

Genius. So doing that.

[09Fx200Q]

:thanks: I appreciate your input on this Trevort.
I ordered from jets r us right before you posted..lol
I only ordered the 127.5, but if it doesn't work out I'll just order the other jets a little later. I went ahead and got the moose racing air filter, I'm going to keep the air box for now and see how she runs with the t-4 exhaust, 127.5 jet and air filter. I'll probably end up doing the K&N mod this winter.

[09Fx200Q]

Pics..

Pretty much stock right now. All the plastics are cracked or broke from the previous owner. The right rear luggage handle was broke so I had it welded and painted them both..getting new flat black plastics, tires,rear brake shoes,tank(flat black),seat(this one looks fine but is worn and uncomfortable to sit on) and some other misc stuff through taobao this winter.

Besides the rear luggage handles the only mods I've done so far are:
Chop the rear plastic fender thing off
Added led lights to the dash and one to the secondary headlight
Fresh pair of new pro taper pillow top grips

[Weldangrind]

Those are among the best China bikes so far. I'm sure you'll enjoy it.

Yeah it has been a great bike and a ton of fun so far! Just hoping to get the hp up a little bit with these mods.. Everything is ordered.. Just impatiently waiting now lol:yay:

[Weldangrind]

That rear fender looks really good, chopped like that. How do you plan to mount the license plate?

I just took a pair of tin snips to it..lol
I live out in the country all dirt and gravel roads so I'm in no hurry to tag it, but I plan on doing the same mod that ostep( think that's spelled right) did. He sent me the link for the tail light on ebay 11 bucks.. Just have to fab a bracket plate to make it and the Lplate fit.

Pic of osteps bike tail light mod, I think it looks sweet!

[09Fx200Q]

[QUOTE=trevort;170089] the smooth side pilot jets 35, 37.5 the non-Mikuni jets work just fine

I'm having trouble finding these at jets are us. Are the pilot jets the same as needle? Sorry I'm kinda a carb noob.. the only carb work I've ever done was take apart and clean an old Ktm 125 carb...got it working and running great though..

The "smooth side" pilot jets located at the top of the page are the jets you need

I did the same mod on my TW200 and my Lifan. Easy.

I thought that maybe you were going to try and use your existing taillight. I was interested in that because I have a spare one.

Thank you again man! That's the kind I ordered so it it looks like I'm in good shape as long as the 127.5 works good.. I have a feeling I'll be ordering some other ones though.

[SpudRider]

Thanks for posting the photos of your XF200. :) The XF200 is not only attractive, it is also a very good, little motorcycle. :tup:

[09Fx200Q]

Ok my 127.5 main jet arrived today and I finally tore apart my carb. The two jets in the float bowl are the main and pilot jets I assume? The bigger being the main and the smaller being the pilot? The main pilot jet (127.5) that arrived from jets are us has a smaller screw head than the stock main that was already in the carb. I ordered the genuine mikuni jet so I'm confused if maybe I ordered the wrong jet somehow (which I double checked) or if they just changed the jet head size and it doesn't matter? The other thing that I found is there is a third jet on the top side of the carb near the needle, not sure what it is for, maybe air? but the jet I received from jets are us has the same size head as this top jet does..:hmm: defiantly could use some help and advice on this one.. Thanks

[09Fx200Q]

Top jet by the needle.

[09Fx200Q]

Jet on the left is stock out of top of carb near the needle.
Jet on the right is the 127.5 main jet that I ordered through jets are us.

I checked my order from my email and the 127.5 is and has the same stock # as the jet on their site under main jets.. But as the next pic shows it has a smaller head than the stock 122.5 jet. Though with the washer from the stock jet it fits in the main jet socket fine.. :hmm:

[09Fx200Q]

Size comparison on the new and stock jet.

[mmprestine]

looks fine to me. did you do a plug chop before changing the main jet?

[09Fx200Q]

looks fine to me. did you do a plug chop before changing the main jet?

Not sure what a plug chop is? I'm a semi novice mechanic... I did take a pic of what the plug looked like right before I changed the main jet.

[09Fx200Q]

This plug is fairly new maybe 20-30 miles on it. Pic took before jet change.

[trevort]

As long as the jet fits and is secure give it a try, if it's an OCD thing and you're gonna lose sleep over it pm me your details and i'll mail you a jet. The third jet top side is the air jet, just make sure it's clean and be very careful putting the diaphram back in the correct way. Now is the time to inspect what the needle clip position is and adjust it at the 3rd or 4th position from the top: moving the clip up the needle leans the mixture and down is to richen. Turn the air screw all the way in until lighly snug and count how many turns did it take, was it 1? 1 1/2? and then turn the air screw back to where it was before and write down on a pad everything that you have done to the carburetor i.e.: main jet 127.5, pilot 35, air jet #?, needle clip n-3, air screw 1 and then neatly write this on your float bowl with a paint pen. This is you base line for adjustments from stock: did moving the needle clip to the 4th position improve response or not? idle is a little rough with the air screw at 1 1/2 try 1 1/4 or 1 turn from tight and so on. Also you plug can still be used for a reading meaniing in a week is the plug color a nice light tan or is it brown another tool is determining if your new jetting is performing for the better or worse for your engine.

[Weldangrind]

Excellent guidance from Trevort.

As a point of trivia, I refer to the large jet as main and the small jet as the slow jet. The screw is the pilot mixture screw.

[Weldangrind]

Not sure what a plug chop is?

Pulling the plug and checking it only references the moment in time when it last ran. If your bike was idling, mid-throttle, full throttle, etc.

A plug chop means to hold the throttle at a specific position and hit the kill switch. After the engine is off, release the throttle, some to a stop, allow the plug to cool and remove it. If you really want to quantify things, tag that specific plug according to conditions (ie full throttle in top gear) and install a new plug.

Repeat throughout the throttle range as desired, although only idle, slow speed, mid throttle and full throttle are really helpful. Show us pics, and we'll try to determine what's happening and what needs to be done.

[trevort]

[Weldangrind]

^ Coolest XF ever. ^

[09Fx200Q]

I went ahead and installed the 127.5 main moved the needle clip to the 3rd position down and readjusted the air screw from 1 & 1/2 out (how it was when I got the bike) to 1 1/4 out. (Great idea to write everything on the float bowl) haven't yet but I will. Took the bike on a 5-6 mile ride. It seems to have a little more top end but not much. I ordered a 35 smooth side pilot jet. Bought 3 new plugs and my pro circuit exhaust and moose air filter should be here by Monday. Im sure I'm going to have to adjust the air screw, check plugs, and tweak things a lot after installing everything. Hopefully I won't have to change the jetting again once the muffler and air filter are on...but I took my best edjamacated guess based on what I'd researched others had done.


My main concern was that I wasn't going to somehow mess up my carb or engine by putting in the smaller head sized main. It seems fine and it defiantly puts me at ease to hear that it should be ok. Thanks again!:tup:

Ahhh yes! I'm defiantly going to do the plug chop once I get everything in and on this bike

Yeah I've read every xf 200 post on here and a few other places I think.. Lol
It's awesome to have so many ppl with so much great knowledge on these bikes.

[09Fx200Q]

Hey Trevort, are the hotcams something I should look into doing? Or is that more of a racing thing that isn't practical for the type of riding I do, which is just mostly cruising county back roads and a little off-road. I do ride pretty hard though and get into it a lot... Love to get this bike to keep the front tire off the ground.

it goes like this

read, read, read, sleep, subconscious analyzes, wake up, carbie zen master!

looks like Trevort has really worked his bike setup to death but you just need to find it all.

sure wish this forum had a little different feature set that i have grown to like on other sites.

[09Fx200Q]

Haha lol yes!

[trevort]

One of the biggest probelms is all the bad advice or wrong part numbers when searching for information on the Xf/Xp bikes, your bike is really a bored out Drz125 engine and shares little to nothing with the Dr200. With the stock gearing or a little larger you can clutch up wheelies with a little practice but with 15,16-44 gearing there's no way a wheelie is ever gonna happen. The Hotcams stage 2 cam is a great item but if you're expecting power wheelies and incredible acceleration it's not happening either. Even though this is a "china bike" I have never treated it as such and give it the same attention as my race bikes and if you notice from my pictures my Q is wearing a Ktm headlight from my 535 exc. Keep the oil changed, clean the filters and on occassion check the valves and your bike will last for years to come.

Right on! What gearing do you suggest for more low end power and cursing speed of around 55-60 (if possible)? And is there any tips or tricks for checking the valves? I never done a valve check or adjustment before.

[Weldangrind]

Trevort, thanks for that clarification. I had forgotten about the DRZ125 relationship.

[09Fx200Q]

Well the vid didn't load..?

That looks really good. I'd like to try a SM some day.

Is that your new exhaust system?

[09Fx200Q]

Yeah new exhaust. I had to get a little creative with the mounting brackets, the bottom brace to found a piece of steel that I bent and drilled to make work. But I couldn't find anything for the top bracket except a half a door hinge..lol it's pretty funny, it's working good for now until I can have my metal guy fab a bracket.. Anyone know if pro circuit makes extensions? I would love to move the silencer back 3" it would mount right to the frame and look better I think.

[SpudRider]

That's a good looking can; you bike looks great. :tup:

P.S. I just noticed your finger in the bottom left of the photograph. ;)

I'm surprised Weld didn't notice it first! :hehe:

[09Fx200Q]

Haha nice spot.. Thanks spud it runs like a different bike, rejetted,moose air filter and t4 exhaust. I'm super happy and I haven't even started dialing in the carb yet :D

[trevort]

The exhaust looks great and hope the bike is performing alot better now, with that said I have a few questions for you: Are you still running the AIS system? Why haven't you put some brake cleaner on that seat logo to remove it? Do you really need passenger pegs and the rear grab bars? Are you still running the stock gearing? From personal exprience use ny-loc or locking nuts on all of the exhaust mounting bolts and make sure that the new lower exhaust mount is a proper gauge and strength steel to support any off-road riding. JTCAndrews original idea of using a steel conduit clamp is a good one only as long as you double it for a secure/strong mount.

Thanks Trevort and yes it's performing like a different bike all together.
Yes I am still running the AIS system. I wasn't sure what that was so I googled it..lol will removing or bypassing it help and do you have it removed on your bike? If it will run better I'll remove it though I might need some instruction.

I've been meaning to take the seat logo off I just don't have any brake cleaner..lol but I'm getting ready to replace the shoes when they get here from ebay, so I'll do it then. I do use the pegs and grab bars so I have to leave them on.. Though I think it would look better w/o them. I'm still running factory gearing.

Great idea on the locking nuts for the exhaust, I'll defiantly do that. I've just got the exhaust rigged on for now.. My neighbor has a metal shop and I'm going to have him fab me some nice brackets. Wish I could find a way to extend the pipe 3" then the silencer would bolt right up to the original bolt hole.

[09Fx200Q]

I'm thinking I should remove or disable the AIS system from my bike thanks to Trevort. Though I am not sure how to go about it?

http://www.chinariders.net/showthread.php?t=5175
This link shows a couple pics, the system I have on my bike is the first pic. The links says it could possibly give me 2hp by removing it? Is this true and could it possibly damage my bike by removing it? I could use some input on this before I mess with it. thanks

Hey Trevort I removed the Qlink logo from the seat..lol

[trevort]

Pics of this logo removal or it didn't happen.

As for the Ais removal goto to the local autoparts store and buy an assortment of vacuum plugs, it should come in a kit with assorted sizes. 1st remove the hose coming from the steel tubing at the front of the engine just beside the exhaust and put the proper size vacuum cap on it. 2nd remove the line going to the top of the carburetor right in front of your air screw and then cap that. 3rd remove the hose going to the top right side of the airbox on the exhaust side and cap it. 4th unbolt the Ais unit from the frame mount under the right tank side panel and then throw it in a box and forget about it and hope that you never need to use it ever again. You could always make a professional looking plate to replace the steel tubing or leave it as is

[09Fx200Q]

Lol.. here you go Trevort!

I should have taken a few pics while I was removing it..

So did you see any HP gain with the removal of the AIS? Just wondering.. I'm defiantly going to remove it anyway it makes horrid noises from around 3800-4800rpms..

:thanks: for the AIS removal walk through man!

I removed the AIS, I capped off the steel tube @ the front of the engine. But I didn't cap off the carb and air box. Instead I removed the "Y" fittings and ran the hoses straight from the black cylinder thing "I'm not sure what it is? An air pump?" to the carb and air box. The bike seems to run the same. Should I cap off the carb and air box? And if I do that should I cap off the black cylinder thing as well?

[trevort]

Remove the air injection system pump/the AIS from the bike and cap off the carburetor and airbox. You should be good to go after doing that

[09Fx200Q]

Cool thanks I'll cap the carb and air box. I said the bike runs the same, but I forgot to mention that it no longer pops and backfires on deceleration.:tup:

Btw what is the "black cylinder thing" that the hoses run to? It's strapped to the frame under the seat.

[katoranger]

Sounds like part of the emissions stuff. Charcoal canister?

[09Fx200Q]

Thanks katoranger. Do you think I should remove it? I'll post a pic here after a bit. I have to take the seat and side covers back off.

[Weldangrind]

Without seeing it, my guess is oil vapour catch can.

[09Fx200Q]

The small module in the upper left looks like it comes from the gas tank, maybe a vent? I'm not sure because I haven't pulled the tank yet and I can't tell by just looking. The bigger hose connects to the air box and the smaller hose under the big one connects to the carb. If this cylinder thing is just a charcoal filter I would like to eliminate it. But I'm still unsure. Any input would help, thanks

[09Fx200Q]

I had to google oil vapor catch can, to figure out what it is and does..lol
It seems semi important to crankcase breathing and overall life of the engine.
But that was just my take on the article I read. How important is it? Do I even need to have it hooked up?

If it comes from the tank, it is indeed a vent / charcoal canister. It's not hurting anything, so I'd leave it unless you get an air lock. If it gives you trouble, you could delete the system and place a fuel filter on the hose that comes from the tank. Make sure that you route the hose the asme way it is now, and zip tie it to the frame.

It doesn't look like a vapour catch can, but I'll respond to your question.

During normal operation, pressure builds in the bottom end of an engine, and it must be allowed to vent (or it will find a way out). Most dirt bikes simply have a vent hose that goes from the top of the transmission (just under the carb) to the ground, routed between the engine and swingarm. The problem with that design is that dust will be drawn in to the engine.

A catch can allows the oil vapour that is forced out to be collected in a reservoir. It is also usually connected to the air box, and that can turn an air filter black due to oil vapour contact.

The simplest way is to use the dirt bike method, but stick a filter on the hose to prevent dust from entering the engine.

[09Fx200Q]

Hey thanks Weld. I'll just leave it alone it doesn't seem to be hurting anything.

[SpudRider]

I'm betting it's a charcoal cannister to collect fuel vapors. Trace the final hose and see where it leads. ;)

[trevort]

Remove the single bolt for your gas tank and dis-connect the fuel line then pull off your tank and inspect where this line is going to, my personal Xf does not have a separate vent line connected under the tank anywhere just a vented gas cap. Remove the charcoal canister, air pump and all the extra hoses as they are not needed and are not going to damage or affect the engine if they are not in place.

[Weldangrind]

If 09FX200Q's cap is not vented, he'll need to retain the hose and at least put a filter on it. He might be able to get a vented cap through Taobao.

[09Fx200Q]

Yeah I took the tank loose and it is an air hose. I removed the charcoal filter and capped everything but the air hose to the tank. Added some extra hose back to the breather hose and it's running great. Thanks to everyone!:thanks:

[Weldangrind]

Is your tank venting with that hose now?

[david3921]

But I'm still unsure. Any input would help, thanks

What you call a small module is a check valve for the gas tank. You need this to allow air into the tank as you use fuel. The cap is not vented. Check inside the gas tank lip and you will see one or two squares. These are for any overflow. If you over fill the tank, the gas will go down the vent line and possibly dmage the check valve. My XF had all of this stuff also. I took off all of that stuff but kept the check valve and line. I could have just installed a longer line and routed it to the bottom of the bike. My Kawasaki has an overflow line that does this. I would suggest you do the same. I put caps at the carb and airbox and removed the rest. I also made an aluminum plate to block off the air hole at the head.
