i have a 2000 yamaha blaster that i traded for my old beat dirtbike i just cant seem to get it running right. it has 123 lbs of compression bypassed tors system and a bypassed oil injection system. it has good spark but seems to be getting too much fuel. i pulled the carb apart a few times cleaning and ajusting it each time and has done nothing. it wont stay running it will start up and bog out allmost immeadtly keeping it at full throttle seems to help a little but not much. when i pull the spark plug it is wet so thats why i belive it is getting fuel it also leaks fuel out of the over flow but i have had a few two strokes and they all did that so i dont think thats part of the problem. thanks for your time any suggestions would be greatly appreciated.

Jets? Clogged reeds? Water in the stator?

reeds are good jets are clean and how would i get water out of the stator if there is any because there is a crack in the housing i guess thats commen but its at the bottem of the case so i would think it would drain out no plus it has good spark but ill look into it thank you

my buddies blaster had the same problem ran fine, but when throttle was applied, the motor would break up, there was water in the stator. take the cover off. GET A NEW SEAL. Then apply something like heat silicone or something over the crack.

yea ill try that but no matter what i do it wont stay running at low or high rpms and to get that little spudder out of it you have to kick it for a while to just get it to do that. it allmost sounds like its being grounded out by something like you hit the kill switch. keeping it at high rpm maby will keep it running for another second or two but it never stays running. do i have to pull the flywheel to get the water out?

yea i tryed the new spark plug its got fresh gas in it im starting to think eletrical because i got it broken and the kid said the tors was the problem but i bypassed the tors and it ran at low rpm ok but when i got on it it just spudderd out and died i messed with it the next couple days and then one day it just wouldent stay running. also could it be seals for the crank case because i know two strokes have a pressureised case.

Due a leak down test. also your needle in the carb might be bad
also do a plug chop
