10.8:1 Compression JE Piston
Edelbrock 39mm Carb
xr400r cam
Ported and polished
3 angle valve job

LRD full exhuast system
modified air box

 

How much is the XR cam. Was there a lot of power increase, top or bottom?? Was there a core charge, was it from Honda. Does the XR and EX have the same rocker arms or would they have to be hardwelded.

 

If I had the money I would have close to the same set up. I think it is great.
