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?
thanks

I can do porting on most any cylinder long as I can get my tool in the ports.
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,
Neil

its basically a matter of not enough power. i want to make sure im at no disadvantage from the 450's. I will think it over because i'm not sure if i want to spend the money to have the cylinder replated. The intake port on my bike is on the cases, not the cylinder, so will i still need to have the nikasil removed in order to port the exhaust port?

Even though it is a case reed engine, yes you will need to have it re-plated.
Any time you break the edge of the plating between the cylinder bore & a port opening the plating will soon start to flake off. Once it starts doing that, its not long before the cylinder & piston destory each other as well as the crank.
