200 Beast + Mikuni carb= Joy!
 
Hi guys! Mikuni carb got delivered today... Bolted that sucker up and what a difference!! Out of the box it runs 100 times better than the stocker did! Messed with all the settings endlessly on the stocker and couldn't get it to stop flooding... Must have been the float setting or the needle. Mik works great though, no more flooding and no more stalling. Still have to fine tune it, but at least I have a good running starting point... Sooo nice not to have the stall/bog everytime I try to ride it :). Okay, I'm doing gushing, we will now return you to your regularly scheduled forums...

Regards,
Stew

Weldangrind 10-26-2009 10:17 PM

Awesome news! I'm getting ready to bolt on my Mikuni, and I'm looking forward to gains. The truth is that my stock carb runs pretty good, but I know there's more in there. 8)

MICRider 10-26-2009 10:23 PM

Makes a huge difference! Even the quality of the piece is apparent when comparing them side by side. I didn't bother with the handlebar choke cause I like the choke on the carb better. I think you would have to bolt the cable holder bracket from the stocker onto the Mik to use it anyway. I think for the price it is a worthwhile mod... Now, I just need one of them Uni filters! Hope you get good results with your carb switch :).

Regards,
Stew

Weldangrind 10-26-2009 10:37 PM

That's funny; I was hoping to report a measurable speed increase with the Mikuni, but the existing carb is good for 65 km/h (40 mph) and that's fast enough!

:lol: You need flat ground not narrow paths with 1ft drops in them.

Another way to be quantitive with your upgrades is to modify yours, and then race me on mine. :) We seemed to be similar powerwise, other than your carb is better than mine, and I'm a bit heavier.

MICRider 10-26-2009 10:52 PM

Lol, never got a chance to wind mine up so I don't know if there is a difference in top speed, just happy the "throw me over the bars" bog is gone :). Idle seems a lot smoother now too, even though it still needs tweaked. They should put this carb on from factory.

Regards,
Stew

P.S. Now, if I can just get it to not handle like a drunken sailor on stilts...

Weldangrind 10-27-2009 12:02 AM

Better front shocks help a lot Stew.

I was thinking more about quantifying speed, and ther's no reason I couldn't go flat out in a lower gear. Let's say I determined that the quad as it sits will do 40 km/h in third; all I'd need to do is repeat the test after an upgrade.

Ok T, grab your helmet. We have testing to do. :D

Stew, its cake. I did it with the Mikuni on the bike because I had read somewhere it "couldnt be hooked up" but then I started looking at it and it looked about the same. I bet it took less than 10 minutes, you can get a stubby phillips right in there.
That being said, if you like it the way it is, heck, leave it ;)

Both Weldangrinds and my Mikuni came with the needle on the lowest (richest) setting. With the exisiting 2 large holes in the air box, the carb made the bike run rich.

This took me a little time to figure out. After drilling another 8 holes (that FORCED me to adjust fuel screw) it runs way better and the plug is ALMOST tan...not quite, but almost. Problem is I'm at the stage where its so good i dont want to mess with it again until I get a proper filter.

Anyways, i think I ended up 1/14 turns out, but as we all know every one of these things is different. Our Mikunis have the screw at the "front" of the carb which makes it a fuel adjustment screw as opposed to having a screw at the back of the carb which would make it an air screw.

I have found some manuals that are close to our carb, but maybe they make so many different types the manuals are purposely generic.

It IS a neat upgrade though! :)

That could hurt the bike if you have the no rev limiter CDI (and believe in it). Even without it, just winding the snot out of it one gear...why risk it?

What do you think of timing it instead? Maybe an 1/8 mile, or even just "from here to the stop sign" type of thing? Most every cell phone made these days has a stop watch function and you & Stew could work in tandem, one on the bike, one on the watch, thens vice-versa

Just a thought :)

Did you hit fourth gear in yours?? I think I only was in third on that stretch you hit 65/km. Even when I risked life and limb driving through that dark patch with the leaves I was only in third gear. Fourth seemed equal to suicide with those shocks on mine. :)

Hey D,

Wouldn't staying in the same gear still top you at 40 km/hr? Does the gear not determine how fast it'll go regardless? ..or would the fact more HP per RPM push that level higher?

Weldangrind 10-27-2009 01:25 AM

Much better idea Pete. I'm glad I started spitballin' the plan; eventually a better one came to the surface. 8)

BTW, I'm not inclined to try a different CDI. I'm satisfied with the stocker and my other upgrades.

Anybody else try an NGK wire? The Crappy Tire part number is 026-2714-0, and it's cheap there. You get the entire wire with plug boot, and it will replace the stocker all the way back to the coil. IIRC, mine was a 1000 ohm improvement. BTW, it will fit on any single cylinder with a stud type plug, including dual sport bikes.

Ahhhh...i was wondering about this..I have an NGK with boot and bare coil end but the OD looks ( I say LOOKS) bigger than the boot that holds the stocker in the coil. The stocker is such a tight fit it almost looks molded on but i dont think it is, I could move it with my fingernail.

So..you got that (8mm?? maybe??) NGK in the stock coil boot? Just pull it out?

Any tips? i just havent got around to prying mine apart yet but would love to know what awaits when I do.

Oh, from my limited testing I expect this thing will do 50mph plus. I'm sure of it. No more comment until i have a GPS pic to prove it. :) :)

EDIT; Every computer i use has a trashed keyboard...sigh.

Just a thought :)

I think time would be challenging. If you think about drag cars over a 1/4 mile, a second improvement takes some pretty good HP increases, if you reduce the length of the 'test strip', how much time improvement will you see? Then you need to factor in driver error. With no tachometer, tough to know if your shift points are similar etc..

I think the answer W&G is an accerormeter like we discussed. :) Cool toy and the high end ones would give you 1/8, 0-60 times etc.. Not exactly a cheap way to do it.

The 'fire road' at Nickelmine would be a good dragstrip if not for the nasty bumps.

It's making me wish I still had access to Pemberton and the runway!! ..but I digress.

Sorry for the damn post flood and hijacking this thread on carbs, I'm feeling wordy tonight.

Weldangrind 10-27-2009 01:36 AM

Whoa. 8O 50mph is too much for me on a Beast on a dirt road.

The coil wire simply unscrews from the coil. Peel back the boot where the wire meets the coil, and unscrew the wire. There is a stud inside the coil that the wire screws on to; no tools are needed. The 026-2714-0 fits great.

True, true...easy to get a car in the 12's...50X harder to see 10's...but realisticly this is all seat of the pants stuff unless we haul out a Lidar gun or something....was thinking of the easist way on the machinery ;)

I hit 4th and let it go for about 5 or 6 seconds til the pucker factor hit. I have no proof, but it seemed like 50 (or close) to me. It was buzzing pretty good. For now I'll just call it 45mph, but those front tires were getting AWFULLY tall looking ;)

Is your NGK wire fatter than the stocker I guess is what I'm asking?
Thanks for the stud info inside the coil!

I just remembered: I once read an article about how surpisingly accurate the Hot Wheels radar guns are (yes, really). We could easily pick a starting point and a finish line and check for top speed at a specific point without reaching actual top speed of the quad. We could do several runs with a particular setup to establish a baseline for each combo.

I can't believe I just said all of that. I'm taking this waaay too seriously. :lol:

Hey, I just thought of something. I think my GPS might be the answer.

It has a 'trip top speed' function, you can reset it manually.

You just zero it, do a run, stop and look at the information. It gives you like "moving time' , 'stopped time', 'top speed' etc and it's accurate. I did this on my YZ in Pemberton wondering how fast I was going. I even think it'll tell you how far you travelled, even without being on a road.

You can stick it in your pocket, do a pre determined run, record your times and speed... change your settings, reset the GPS, and do another run.

Anyone have a Blackberry? Even if you dont have a GPS app you can still use BB Maps for rudimentry functions.

Stew, your GPS device is much better suited to this than a Blackberry come to think of it. Garmin?

Hey Pete,

You're getting me confused with MICrider, who is Stew, and who started this thread we've so eloquently hijacked into a speed testing discussion. :) It got a little hectic so easy to do! I try to keep my real name out of the public forums, (for reasons I still don't know just do :)) but if you check our PM you'll jog your memory! :)

I do have a Blackberry with the GPS ap, but where W&G ride there is no cell coverage, and when I tried to load it there it flashed at me that it wouldn't work without it... it struck me as odd at the time, since GPS should be seperate from cell coverage.. I'm thinking perhaps it locates the maps via the cell network as to not store them in the phones memory, and just shuts itself down without the coverage.

My GPS is a Garmin yes, and it probably does way more than I use it for.. but I know it has the functions I mentioned before and is quite accurate.

PCD chap, if you ever get out to BC all three of us need to have some pops and a laugh. :)

After I thought about the cell/gps thing it made sense to me, so you can chalk Telus up as a cheater on the GPS ap. Or perhaps its Blackberry itself who's cheating with their programming.

Sounds like a plan if I can swing it one summer. Best thing is I can buy a bike, have it delivered to one of you, run it for a few days, then sell it half price. What colours you like? :)

W&G: Yes, it is a real NGK as far as I can tell, with Chinese labels all over it. Package looks same as C/T, wire looks identical...probably has bailing wire for a core knowing my luck.

Mostly clearcoat in my wallet lol.....well, I know liquor is quicker, but I've stuck to beer for the last...oh.....30yrs or so. A Ceaser is nice now and again, but the hard stuff was becoming a little too tasty in my early 20's...the mornings, afternoons, and evenings were getting a little rough. However, I've been known to knock back a few beers here and there ;)
