LF200GY-2 Year 2007 *Help*

[Diggy]

Hello, Im new to this site and also new to riding moto/dirtbikes.
I was able to pick up a LF200GY-2 from someone from around my area.
I brought it to my father in-law farm to ride around and it took me 30 mins to get use to it, and I love riding.. Very dangerous but exciting at the same time.

I am having a problem having it idle, Ill pull the choke out all the way and turn it on by the electric starter and it starts up good Ill try to let it warm up a good 5-10 mins before the ride, problem is that I have to hold the choke up and when I hear it start running a little higher in RPMS ill close the choke but it will shutoff with in 10 secs - 3 mins.

I tried the choke out totally by holding it up and it runs forever until I let it go. Also I was thinking of just updating the bike and is it even worth getting different mods for it and can I? Should I change the plastic pieces, because some people say it rattles when riding on it, also the carburetor is 7 years old and I don't know if the last person owned it drained the carb when storing it for winter time, I live in Canada:) do I have to stay with the same thing or can I get better pieces.

So should I change anything on it at all if I have the money, is it worth it or not? The manual I got with it shows that there are headlights and tail lights and turning signals but mine does not have any of that, is it hard to get a head light put in the front of it because I may want to do some night time riding, any suggestions? also the front shocks looks like the basic shocks I do see other people having better looking shocks probably better quality... can I put any on this bike? is it worth it or not? Also why is it sometimes I hear a funny noise with the brakes when I pull it backwards sounds like vibration or maybe sand in the discs? have you ever heard of this before? what else could it be, I pressure washed the bike and I don't really hear the noise anymore, so I'm guessing its sand..

Thanks a lot if someone can give me some good ideas.
It would be much appreciated,

Kevin-Diggy :)

Welcome, fellow Canadian! :D Where are you from?

You would have earned extra points if you posted pics. Please show us your bike. Once we see it, we can make headlight and other recommendations.

In the meantime, this is the cure: http://www.ebay.ca/itm/Carburetor-Carb-ATV-Dirt-Bike-Quad-Honda-MIKUNI-30mm-/151151031299?pt=Motorcycles_Parts_Accessories&hash=item23314db403&vxp=mtr

[Diggy]

Im from Canada, Ontario. This is my first moto/dirt bike and very excited.
So much fun to ride in the bush and on the road. I would prolly do most of my time riding at night since I have kids and they need a lot of attention :). Im not sure if I should even add a front light/back light or even make this bike road legal. I use it to have fun in the dirt and learn how to drive a moto bike. I need to know from the experience, what should I add to the bike or is it even worth doing it. Can I clean the carb I have in it now and put it back in? or buy a new one? The shocks are they good shocks or should I get different ones?

So would that carb. be the same as what I have in it or different? Please give me some good ideas what I should do to the bike to make it much better?

Here are some pictures of the bike and it was bought in BC, Canada.

Thanks,
Kevin

U can fine tune the stock with http://mypitbike.ru/downloads/PZ22PZ26.pdf

Awesome information about carbs. I will keep this a read up on it and figure out how it all works. Is that the same carb as Weldangrind posted me the AD to ebay? So this would be the best carb for my bike? are there other carbs out there that are better or better quality? I do not know nothing about carb, I would like to look at the different types out there...

Thanks

[Weldangrind]

Nice bike!

The carb I linked to is a Mikuni, and your carb is a Keihin. Nothing wrong with a Keihin, but jets are hard for us to find in Canada. Mikuni jets are easily found, including at your local Yamaha dealer. I'd buy the Mikuni, buy some larger jets for it (which are really cheap), and enjoy the bike for what it is.

You might be able to dual sport the bike (which means to add lights and a horn to make it street legal), but it depends on the laws of Ontario. We used to be able to dual sport our dirt bikes in BC, but not anymore.

The stock front forks are just fine, but they could benefit from an oil change. That's easy.

Can you show us a pic of how the front number plate mounts? We can likely recommend a headlight from there.

[SpudRider]

Welcome; we are glad you joined us. :hi:

As usual, I agree with Weldangrind. ;) I suggest you clean/tune the carburetor, change the fork oil, and enjoy the bike as it is. After you have ridden the bike for a while you can make better decisions regarding modifications, et cetera. ;)

[Diggy]

Okay sounds good, Ill take a picture of the front end to see about head lights. I'm a newbie at this so when you explain things please explain everything that Ill need to complete it. I did not know about Jets when you told me about them if I buy the one from ebay.

The front forks are good? why does my forks look so old and ghetto compared to some forks out there, the oil in them I should change your telling me, is it really hard and how often should the oil be changed in them?

Another question is about the plastic pieces on my bike im not a big fan of, I got cracks on one side and they will prolly not hold up for long, is there away to find a better plastic or whatever you guys recommend if I want to change the two pieces for the gas tank and the two side pieces on the side, Im not liking bluish / yellow color.

[Diggy]

So I have some pictures of the front end let me know what you think.
I'm going to go buy the new carb from e-bay!

So when I get it in could you help me learn how to install it properly?

Also would it be a good idea to get anything else?
example something like a cable, break or throttle cable?

I don't know, not experience in things breaking with bikes yet.. I just wouldn't want to be so far away and something small breaks..

Nothing better then getting some info from the experience. What usually goes a lot on a bike? cables?

Thanks again for the help guys, more people the better.

I am pretty sure that you have a dirt only model. Likely that you will not be able to register it for road use. Really depends on the local laws in Ontario. I know that it won't happen in Kansas or many of the US states.

[Diggy]

Hmm the manual that I got for it shows that I can install different mods on it, and it would be nice to have a light in the front for night time riding. I don't really need to make it street legal but comfy night time driving would be nice with nice headlight.

I have cracks as well in the side plastic pieces ill show you pictures of it, is there away to get different better quality pieces that will fit good and not rattle /squeak etc.

TIPS ANYONE: I got the new carb from ebay link downbelow.. Is there anything else I need to get once I get the new carb here in 10-20 days.. Should I buy new jets? how many jets do I need and if there is anything else let me know please.

Aswell, the manual I have for the bike does not show how much liters of oil it takes, does anyone know how many liters I would need? One bottle or two?

Thanks for the info.. let me show you the cracks I got in the plastic areas.
Any tips would be great, can I re paint these pieces? or should I get new ones? let me know if anyone has any good ideas.

[Weldangrind]

So many questions! :D

Let's break it down a bit, and just deal with a couple at a time for now. Yes, you should buy new jets for your carb. I can provide eBay links if you need.

You'll need about one litre of any 15W40 oil, even diesel oil from Walmart.

Most decal are made from ABS plastic. That "acetone" trick works if u knows how | "Re-weld" trick using soldering iron/ heat gun …

[Weldangrind]

You can also glue the plastic back together from the back side using ABS cement.

[Weldangrind]

Slow jet: http://www.ebay.ca/itm/Mikuni-VM28-486-Pilot-Jet-25-VM28-486-25-/151075777977?pt=Motorcycles_Parts_Accessories&hash=item232cd16db9&vxp=mtr

You can certainly get them for less in Canada. Just remove your jets and take them to the local Yamaha dealer. If they don't have them, they can order them. They'll ask you what type of bike, but don't answer that question. Tell them that you don't know what type of bike, and that you bought the Mikuni on eBay. Once they look in their catalogs, they'll find the jets.

[Diggy]

I went to a motorbike garage in my area to ask them about different things and how much they charge for labour etc to get some info as well from them. I asked them about changing my oil in my bike and my manual tells me to use 15w 40.

The person from the garage told me that 10w 40 would be ok too.
I have a picture of the oil I bought from them.
I just want to make sure from the Lifan group of people that this will be ok, or should I run different oil that you guys recommend.

Thanks for your input guys much appreciated.

[SpudRider]

The 10W/40 engine oil you bought is fine. :) However, I prefer the excellent quality, and low price, of 15W/40 engine oil. ;) You might enjoy reading these two essays on engine oil for motorcycles. :)

[Weldangrind]

X2 on Spud's comments. The oil you bought is fine, but it's expensive. Regular 15W40 from Walmart is all you need.

We can certainly guide you on changing your oil.

[Diggy]

Great, it only cost me like 10 $ for it. Thanks Spud for the tutorial on different oils out there and how it all came too. Very interesting. Ill remember next time about the good old Walmart oil:)

I have a window at the bottom of the engine showing a little darkness.
If you have time, tell me how you change your oil the proper way and also what else do I need to keep my engine good and running for the next season. Im keeping my bike in the garage, my wife wont let me bring it in the house! haha.

Is there a filter? should I check out the screen if there is any? and where is it? do I start the engine and just idle it for 10 mins then drain or does it need to be moving in gear etc. I cant really take it for a spin out my neighborhood because I don't have my M licence and I still need to get the bike if its even able to drive it on the road. Would be nice tho:)

So many things to do and I don't even know where to begin.

Let me know how you do things.

Thanks

**WAITING FOR NEW CARB ** very excited!

[Weldangrind]

Put your bikie on the kickstand. Look near the gearshift, and you'll see a very large nut; remove it, and a spring and screen will pop out with it, followed by a litre of oil. Make sure you have a pan under the engine.

Once it has all drained out, clean the screen. Use some carb cleaner or WD-40, and place it back in the hole, rubber end first. Place the spring after that, and then screw the large nut back in place. DO NOT over tighten the large nut, ot it will crack; ask me how I know. Once the nut is secured, fill the engine with oil through the dipstick hole.

The dispstick is not to be trusted. Stand the bike up as staight as possible (get help if necessary), and check the sight glass on the right side of the engine. The oil should be at the upper line.

Have a cold beverage.

[Diggy]

Thanks for the info, I will definitely have a cold one after that! haha

[Weldangrind]

Happy to help. let us know how it goes, and feel free to post pics of the process.

[Diggy]

When taking most items off the bike now, I was looking at the carb that I will be replacing. Im trying to figure out how to replace it without taking more stuff off. If you own a LF200GY-2, do I need to take the motor off to replace the new Carb?

How much stuff would I need to take off the bike to replace the new carb?

Thanks

[katoranger]

You do not need to take the motor out. Remove the airbox and it should come out that direction.

[Diggy]

Awesome,
Yeah this is my first time doing this so I may need some step by step help.
Im waiting for the new jet to come in, and I will have to play around and learn from the old one. If I get into trouble Ill ask for help here.

Thanks for the help..

[SpudRider]

Before you remove the air box, I suggest you try the following procedure.

Remove all cables from the carburetor.
Completely loosen the hose clamps on both side of the carburetor.

Pull the carburetor out of the intake manifold of the engine, pressing it backwards into the hose from the air box. If the hose from the air box compresses enough, the carb will separate from the engine. Once it separates from the engine, pull the carb out of the hose from the air box.

When installing the new carburetor, repeat the procedure above, in reverse. ;)

[Weldangrind]

The airbox will require removal, since the carb is bolted (not clamped) to the intake tube. Remove the airbox hose clamp, remove the air box, remove the two nuts that secure the carb to the intake tube and slide the carb out.

That is, after removing the cables as Spud recommended.

[SpudRider]

I should know better than to give Hondoid advice. ;) As usual, Allen was correct. :tup:

However, I am curious. Does the air box have a hose leading to the carburetor? If so, why can't you merely unbolt the carburetor from the cylinder head, and then pull the carburetor out of the airbox hose?

[Weldangrind]

Depending on the airbox hose design and material, it might be too tight. Also, you risk damaging the hose.

Lifanda's hose is too tight, and I must remove the airbox to remove the carb. I've since gotten rid of that awful box and switched to a pod filter.

[SpudRider]

I understand; the air box 'hose' on my Zongshen Sierra was made of plastic, not rubber! :wtf: I replaced this hose with the equivalent Yamaha part for the TW200, and removing the carburetor is now an easy task. :tup:

[katoranger]

I was going by memory. Also switched to a pod filter. There is not alot of space in that area. Airbox removal was simple.

[Weldangrind]

I understand; the air box 'hose' on my Zongshen Sierra was made of plastic, not rubber! :wtf: I replaced this hose with the equivalent Yamaha part for the TW200, and removing the carburetor is now an easy task. :tup:

The other part I didn't share well is that the intake tube has studs screwed into it, and they support the carb. The carb needs to be pulled back off of the studs, and the intake hose doesn't allow any lateral movement. Super annoying.

[SpudRider]

Indeed, that is an annoying configuration. :ohno:

[Weldangrind]

The pod filter totally resolves it. As well, the pod is protected from water on Lifanda, due to the rear fender design.

[Diggy]

Okay I got the jet in the mail now, two pieces. Im hoping its the right ones because the picture that I seen on ebay kinda looks different then the ones I got in the mail. Here are the pics of them.

Could you give me some info on where they should go and how to install it properly.

So when I take the old carb out is there anything else I can do to that area to clean or to take care of somethings before installing the new carb.

[Weldangrind]

Do you already have the new carb?

[Diggy]

Yes, carb is in and I got those two little pieces witch is the jet.
I just don't know the proper way to install them.
What Ill do is, take out the old carb and do some research on that old carb, then when I get some info from you on where and how to install it and the proper way with the Jet in the High or Low position, what would you recommend....

Let me know any info that you know what I should do when installing this carb..

Thanks

[Weldangrind]

Jets are super easy. Just turn the carb upside down, remove the four bowl screws and remove the bowl. You'll see the main jet screwed into the emulsion tube, which is screwed into the carb body. Just hold the tube with a small wrench and then unscrew the main jet. You should see that the main jet says 100 on it.

The slow jet is next to it, down a deep hole. Insert a small flat blade screwdriver into the hole and unscrew the jet. You should see that it says 20 on it.
