well i have 2 race ready blasters, the one i bought and then burned the clutch out in practaice at budds(well call this one orange), so i took the carb and intake off the orange and put it on my primary race bike(well call this one blue) when the carb was on orange it ran fine, but when it was on blue i had a similar problem as i have now, so when we went to va beach the problem still remained but i had tryed about 4 jets smaller to try to correct the problem, wrong the rings and piston were shot on blue and i dident have time to have it bored or order a new piston, so we ran home that night to get the motor off of orange, got it brought it back took oranges intake/ carb off blue motor and put it on orange and put it in blues frame now we have the same engine and carb and intake with the same type of pipe(have the same one on both bikes) so it should run the same wrong, the problem is that when the throttle is wide open it wants to cut off like it cant get enough air or something, me and my friend(former ama bike pro) messed w/ the fuel screw which helped a liltle bit, and just for refrence it runs best with a br8es in it, with a br9es it will barely run, with a br7es its better than a 9 but not as good as a 8, not sure if it has a air leak(possible suspect) also it smokes even after it warms up(im running amsoil synthetic 32:1 4 oz to a gal) also could this be from the pipe leaking? not sure, knew there was the experts at bhq so came here some body help me!
thanks
