Designed for the
Cruiser Magic
Cruiser Performance
 Thunder Air Kit
and other inlet mod systems.

This is THE Factory Pro quality TUNING KIT as recommended by most every online VT750 guru.

Rather than try to guess at jetting that "works for everybody at any altitude, humidity and temperature" (a.k.a. = impossible!) - This kit includes jetting specs for a bike jetted in standard air temp, pressure and a pressure conditions.
It ALSO includes OPTIONS so that you can jet YOUR bike in YOUR location so that it runs as perfectly as possible - This is not some unrealistic "put this main jet in and put the clip in this position and everything will be perfect at every elevation, any temperature with any exhaust" kind of jet kit.
We are tuners - not "sell'in da dream" marketers.

This kit was developed on the Factory Pro designed EC997 dynamometer - the only dyno that was designed to tune for best power and maximum smoothness in realtime - not a common dealership level dyno. A lot of the one jet, one needle, one setting jet kits were done with dealership level mass market dynos.... So - that's not a first choice in products.

This kit contains long life Celmat30 alloy needles and Steel Allen Screws for the float bowl and it adds more low-end / midrange, if the proper main jet is selected, the best top-end power. Easy to install and tune - no slide drilling.

It includes #42 pilot jets and a range of Keihin Scaled main jets - including proper Keihin scale 132, 135, 138, 140 and even the "way big", 142 main jets -
