Porting Questions

[ZillaRider02]

I am planning a top-end on my Shee in the next week or so. The setup now is as follows: Standard bore cylinders with Patriot MX porting, Timing +4, Lightened Flywheel, T-5's, NOSS Head (18 cc domes), Stock carbs (Tors removed), Pro Design Intake.

 

 

I ride 99% sand and like everyone else, would like more power. I'm considering sending them back to Patriot for the Dune port, bore and pistons or another builder. Since the cylinders are already ported, how will this effect further port work? I've heard great things about F.A.S.T. and RB lately. Does anybody have another suggestion for porting? Later down the road I would love to have a set of Cubs, but not this time. Thanks guys.....

Most likely they can be worked with. It's hard to tell exactly what was done to them in the start, but MX ports usually don't take a whole lot of port timing changes, it more in the shape of the ports.
