Hello, I am getting ready to do a full Port and Polish on my 2003 Shee. I already have the following mods. Toomey T-5's,Reeds,Boost Bottle,Cool Head. I am trying to decide to go with the full race port or just a mild port. I do alot of dune riding and racing. I am also going to do a clean up bore and install wiesco pistons, lighten the flywheel and advance the timing. Will I need to purchase a racing clutch with all these mods? Is there anything else I should do to avoid headach down the road? Thanks for any advice you can give me.
