Have any of you guys had your 99 carb go bad. I ask all these things because my yz is running stupid.
About 2 months ago I went Riding at Gorman. It was a cold wet day so I thought the bike was just running rich because I didn't change the jetting for the alltitude. So after changing some jets and messing with the air scew I was able to at least ride it.
So I get home dismantle the carb clean everything the silencer was repacked clean air filter and so on. Rode gorman the next weekend same thing.
So the bike hasn't had a top end since I bought it so I figured I would do the top end. Mind you the bike was running fine first kicker everything.
The piston was good cylinder was good reeds looked like they needed to be replaces one side was warpped
So new parts
Top end OEM
new kill switch
Different coil Thought that might be the problem
Rejet back to pro circuts reccomendations.
And then a ton of other parts not related to the motor.
Its not sucking tranny fluid
The power valve is functioning
It revs to the moon not under load
But under load at about half to full throttle it bogs.
Not enough fouling to kill the bike but it totally kills the power say if i am in 5th gear pinned I can't go faster then maybe 45mph and that is with a 50 tooth rear sprocket.
I have a new kehin carb 39mm is what they reccomended coming from sudco that should be in on monday it dosent have the little solenid to lean the mixture at top end but I don't think that will be an issue. Considering most guys disconnect it that I have takled to and this year dosent have TPS either.
Any thoughts would be appreciated.
