I can do porting on most any cylinder long as I can get my tool in the ports.Hey i know that you do a lot of work on quads but i was curious if you are familiar with newer dirtbike motors. i race a 2005 honda CR250 and have been looking for someone that could do porting for me. have you done any work on one of these motors or is there anyone you could recommend?
What is it your needing out of the engine, not enough power or not enough rpms.
The 04 cylinders are nikisal plated bore & if any port changes are needed, the plating will need removing before the work & then re-plated after the port change. Cylinder bore re-plating prices start at 179.95.
If the cylinder has been used or damaged enough to have been sleeved with an iron sleeve, then porting changes can be done any time a bore job is needed.
My porting prices start at 250.00 & will be porting like a sponcered pro rider would need.
Thanks for asking,
