The carb is this one http://www.giobikes.com/Performance-...rchPhrase=1721 They usually go up on auction everyday.
As for checking the plug at WOT, you need at least a 30 second WOT run under load and then kill the ignition while still at WOT and then check the plug.

wow i dont think ive ever done a full 30 second run at wot.. that seems crazy, to run it at wot for 30 seconds...

esp cuz either mine motor is revving faster with the fmf pipe or its cutting out like crazy.. hmm just going to have to see this afternoon..

thanks for the link i am checking it out now..

Really, a quick boot up the road is all it takes.

mizke · 08-12-2010, 10:27 AM

i have to take it out of town to do that.. if i take it for a quick spin down the road here and a cop sees me.. its off to the impound lot for my quad..

Buy one at auction..........mine cost $30 landed (though I ship multiple items).

mizke · 08-12-2010, 10:32 AM

ya im watching the auctions, gotta wait till the end of the month but i have vacation time saved up.. so i will take a day off so i can watch the auctions closely and win the performance carb, cdi, and maybe some shocks..

if not then just the carb, and head down to tj's to get a set of pro taper bars for 80 bucks and some new bar ends, also going to order a gio gas cap so i can run a vented cap..

You don't need to be near the computer to watch the auctions. Just set up an account (I recommend your China Riders user name, so we don't bid against you), and then select as many items as you wish to watch. Once the auctions expire, you'll be able to view several at a glance and see what they go for. That'll guide you towards a fair price.

BTW, I found Keihin jets at Honda and Mikuni jets at Yamaha. Just sayin'.

mizke · 08-12-2010, 12:53 PM

the place i went to works on all brands.. but only had a select few for my carb.. im prolly just going to end up switching over to the mikuni beat upgrade carb.. jsut gotta wait for rmatv to ship the ones i ordered last night and see how they do.. got to today so im going to go out here in a little while and test out the 92.5 jet see what it does since it is 4.5 sizes larger then the stocker

mizke · 08-12-2010, 01:17 PM

92.5 is a no go, let it warm up.. go moving and then punched it and as soon as the throttle lever hit full throttle it started a really fast backfire and hesitated like crazy.. so will do a follow up monday after the 98 and 110 main get here

SpudRider · 08-12-2010, 02:47 PM

The engine backfired, and hesitated when my engine was running rich.

When I installed a smaller main jet, the symptoms disappeared.

mizke · 08-12-2010, 03:07 PM

it cant be running rich that would not make sense.. ok well in goes the 88 main and i will see what happens..

before i reinstall another main, im going to pull the needle back up one notch.. i lowered it a notch yesterday before buying the jets thinking i would have to neways.. i will see if that will make a differece

mizke · 08-12-2010, 03:40 PM

stupid needle jet was the problem, moved it back to the middle notch. then took it for a spin in the back yard.. no hesitation what so ever in the mid to wot ranges.. also explains why my plug was black. when with the stock muffler it was tanish brown. so i guess with the stock jet being a 88 having the 92.5 installed its safe to say its not going to be leaned out to much..
