Where do you find one of those? :confused: I have never heard of that exhaust. I would guess it is pretty nuch the same as any other exhaust out there bud, so try a 165 main jet.

I am talking about a Keihin (stock type) jet by the way. I hate those DynoJet jets because they just confuse people. I always try to only use Keihin jets in a Keihin carb.

165? That sounds huge, my GF is running a 150 with an FMF slip-on.

Oops, I meant to type 160 before. :eek:
That still may sound big, but it is a full exhaust, and he has a K&N, and I am just trying to find him a good, safe starting point.
