hmm, i may be interested in the slipon..i sent you a pm

 

Back at you.........

 

If you arent going to jet it, then just leave it stock. Do it right or dont do it at all.

 

The point of an aftermarket exhaust is more power.

 

You race lawn mowers...no one increases their fuel requirements??

 

When I bought my Yoshi, jetting instructions set, if I don't make holes in filter lid stay with factory setting. But after I started, head pipe was glowing and turn blue and red just on idle. Was to lean, at least try rise needle and turn out air/fuel mixture screw 3 full turn. I em switching to Edelbrock. Jetting this twins is a pure nonsense. IMHO

use like 165 and 170 jets and buy a k&n and take off air box lid......trust me you'll like it w/ more power instead of losing it and just the sound

 

get a dyno jet kit, and do it right

 

I understand and agree. And since the power gains are best achieved by allowing more air/fuel into the engine, its kind of like putting a nitrous bottle on and not installing the hoses. Minimal increases will be had with a stock jetted slip on, and you may be hurting the engine by running too lean.
