I've used rayaracing and he does great work. Os rocket is also good, but if it were up to me, I'd go with ray. He would be my choice. Again, both do a great service to racers and bashers by allowing us to extend the life of the motors we buy. Before this type of service came out, you really had a hard choice to make whether to rebuild or buy a new motor. Now it's alot easier to justify spending 300-400 on a motor cause you can always get the sleeve pinched once the compression is gone.

Default Sleeve resizing Equepment

EVERYONE THAT IS ANYONE RESIZING SUCCESSFULLY TODAY is tooled by RayAracing. And my track record looks damn good with my reconditioning-resizing service. Defenitly worth the years income I sacrificed developing RayAracing tooling, and a the most prefered resizing process in the world.

There may be one or even two resizing guys not using my tooling, but not to worry, the accuracy is not is good. RayA

I haven't been able to run it much because of the weather but it does seem to want to run a little hot, around 240-250. Does anyone have any ideas on whats going on? I might have it just a bit lean on the top end. First race next weekend so I guess I'll see how she does.
If compression feels light but you can feel a notch at the top of the stroke then you likely have a little slop in your crankpin/con-rod bushing.
