If you have a Q-2 dump tube in them, you need to order the Q-0 dump tubes, and change them out. That's one thing I had to do to mine, to get them to run right.  Talk to Jeff at Fast Racing.  He can steer you in the right direction.

q2 dump tube?

I dunno where you got those carbs but I think 360 is much bigger than what we ran in 34mm flatslides. Talk to Jeff at FAST if you want but if I remember right 250 or 260 mains were what 34mm flatslides. As far as it not idling down that may be the slides not going all the way down.

I got some 34TM's I using with twist throttle. I found that these carbs need just a little more cable than my stock carbs. Try adjusting your cable, then sync again

yeh 360 is massive.

250-280 is where they run.  what size motor ?

bike will still work with q2-389 dumps tubes (emulsion tubes( they are the brass jett the needle slides into)), q0-389 is what was recommended to me from wildcard racing. 

 

 

 

who did you buy the stuff off ?
