I'm boring my CVO 103 out to 107 and I have bought and installed s&s .625 gear drive cams. I've been told no one makes a 107 high compression piston that will raise the compression high enough in
the 95cc heads.
What are my options? Does anyone know if someone is making a piston that will work?

 

Call Fuelmoto.

 

Thanks, I'll give them a try.

 

We'd have Wiseco/J&E manufacture some, once the cylinder head work was performed, and at that point, cc the chamber volume.
Bondo mold of the chamber, along with precision dimensions is how we have established this many times.
Our 6cc, 143" pistons are an example.
