I just installed a Yoshi Slip On, Pro K&N kit, and dynojet kit at 146/148, 3 turns out on the mixture screw, airbox with two 1-1/2 holes in the back (2000-2200ft). It runs fine, but it seems like it has lost some top end. I had another thread on this but it has disappeared. Should I try it with the 144/146 mains like Dynojet reccomends or would this be even worse?

 

I have some issues with the dynajet and yoshi system also...it rocks in 1-3 gears but no top end. I talked with yoshi r&d and they said try going up a jet size...I havent tried yet, so maybe tomorrow

 

Do you have the full exhaust or just the slip on? Let me know what you find out.

 

ttt for one last try

 

well.... i got a white brothers R4 slip on... and i had to go up on my main jets to a 160, and 165 before it ran good. might wanna try that... or at least 155, 160

 

i went up to 148/150 and it seems ok, but I havent opened her up yet...need to go riding [img]i/expressions/face-icon-small-smile.gif[/img]
