400 Yoshimura Jeting sizes ??
« on: March 18, 2012, 10:14:08 PM »
Anyone know what mod's you have to make to your jets or carbs to run have a Yoshimura Cyclone and not run Rich on the fuel.

Mines a 92 Japanese import, with a full Yoshi Cyclone and she runs rich. I do have adjustments on the needles, they are set half way and my pilot screw is set 1 and a quarter out, i have stock main jets and pilot jets and my O-rings are good. Pulled apart the carb completely and they are all in good shape. Just running rich because of the needle height, the pilot screw or the jet sizes..

So what set-up does everyone who has a yoshimura use ?

heres a photo of my bike so you can see if you have the same system.
