Jetting

I am thinking about getting Keihin 13 series jets in the 160 -170 sizes and i am wondering if they will fit without an adapter or anything like that.:confused:

yes, the 13 series is the same series as the stock jet. all you need to do is unscrew the stock one and put in a different one. i hope you have some mods done to the bike or it will do nothing but slow you down.

I put a 168 in with the full system and airbox lid off and i think it runs great it just hesitates a little in a mid idle but runs good. Does this sound good??? or ok???

go down to a 158 or 160 and it should run better.
