Alright so Im jetting my carb, all I have is a fmf head and powercore 2 pipe and a k&n filter. At 230 it was deffently lean so I bought a 290, 280, and 250. It seemed like the 290 was too rich and it just bogged out at wot, and the same with the 280 and 250. I sort of pops and backfires and it just makes the quad unridable.. I can't figure out what to do, help please. Thanks
 
I dont think thats the problem, my air screw is 1 1/2 turns out but I was curious if something else was wrong so I put the 230 back in and now its doing the same thing as the other jets just not as severe.. I can't figure out what to do now...
 
Anyone?.. Also I pulled my jug off and everything seemed good, the only thing I wasnt sure of was when I looked into the top end on the inside at the top there was oil is this normal? Could a bad crank seal be causing these problems? I really dont know too much about this stuff help would really be appreceated, thanks.

If you run Ur bike rich.Have u rebuilt this blaster lately?I can only help only on how much info i get.
 
No, also I noticed the reeds and the manifold that connects the carb to the reed cage was soaked in gas, is this normal?
 
I rebuilt it about a month ago and it was deffeintly lean, so I got new jets a couple of days ago and thats when all these problems started
 
I rebuilt it about a month ago and it was definitely lean, so I got new jets a couple of days ago and that's when all these problems started

Did the blasty run alright then or was it making ur plugs wight or if you still have your tor's
 
Tors is gone and I should of mentioned I bought it not running and rebuilt it about a month ago, it was running fine I just knew it was lean because the main was stock and it had a fmf head and powercore 2 pipe and k&n filter, so i decided to richen it up and thats when these problems started, I went from 230 to 290 to 280 to 250 and had these problems so I put the 230 back in to see if it would go away but its still happening, it really just seems like its not burning all the fuel or not getting enough and sputtering and bogging out at wot to the point that it dies.
