110 steel sleeve CG

It's the way two different countries do engine size calculations. We call them 66cc real displacement, other places like china they mathematically figure them as a 80cc or something like that. Lol
 
I think they refer to the 110cc head as a trapezoid style cylinder head. Maybe some of the professionals can chime in.

I have 10 good running CG's right now and have built around 30 over the past 3 years. These 110cc engines are Duds!
 
You can preorder a smolik head supposedly for the cdh 110cc, so I got to look into that 1st. I'm going to try & get a degree wheel on it this week some time & get port #'s to run by you guys, I'm thinking from playing around with it, the cylinder needs raised 2-3mm & then decked with some port clean up. Then with smolik head it should be a good runner! Just me thinking out loud!
 
I like the rdm cranks but dont have $300 to throw down on 1 of them yet, plus I think you can have them build it where it uses a ktm50 magnet & ignition set up which I think is adjustable.
