Dk, the Saito 100 exhaust routes right out of the bottom of the cowl, you will need an extension to get it fully out of the cowl. I'm quite sure the 120 can be routed the same though. On the Kangke Cap I would definetly recommend replacing the fuel tank, with a dubro 14 oz square which fits right in the existing opening even though the opening is round. My kangke fuel tank just split the other day, it split right in front by the stopper, if you really want to use the existing tank, dont tighten the stopper screw to tight, that will help.

The Vertical performance with the Saito 100 is excellent, I couldnt ask for any better, I am very pleased with this setup. Daz...
