Alright all. I've got a new build coming on. Today, I finished my engine. Here are the specs. Anyone have an estimate on the HP for something like this one?

155cc build from Base RCM engine

56mm bore x 63mm stroke

Akunar high dome piston, machined custom

Akunar +6mm stroke kit fitted to a GPX crankshaft

Zongshen BVH fully ported

Custom ground camshaft (mimics closely the Z40 but a little less lift)

Takegawa 28mm intake

Mikuni TM28 flatslide

Yoshimura Dax pipe

Flywheel and Oil Sling shaved

All this will be mounted to a 1975 Honda CT70 in metalic sparkly green. The build of the bike starts right after my kitchen is in and will be documented in the Vintage Honda section. But since I had a china engine for it, here we go.
