The TVI 720 I bought from Punisher has a Mikuni 45 on it. The accel pump is not functional. The idle air screw can be removed without any change in rpm. The bike runs great everwhere but on a snap throttle from idle. I am thinking about hooking up the parts to make the accel pump work but am wondering if I might have to change the pilot jet also (because of the 'no effect' of the idle air screw). Anyone with a big bore/mikuni combo care to tell me what pilot they run with the accel pump working? The bike runs very well off idle all the way up so I don't think I will have to do any needle or clip adjustments. Any help or advice would be appreciated.

 

My 720 seems to like a lean pilot (40 or lower) when the pump is hooked up. Remember to use the 50 accel. pump jet and set it for a short burst, not a drawn out stream. Main should be in the 140-145 range.
