I'm getting a Supertrapp IDS2 Quiet exhaust with header pipe and was wondering if anyone else out there had one. I will also be replacing the stock filter with a foam Uni-filter. Might remove the sorkel as well. Can anyone tell me what size main jet is required with these mods?

Thanks in advance for the information!

 

Most use the dynojet jet kits. Kawi offers obtional jets, I believe a #142 and #144. Cost is usually $4.50 each. I have tried the dynojet dj138 with the mods you are speaking of but using a stock carb and it worked graet, cost $2.00.

Try and get the jet kit it really goes well with a pipe and filter.
