I currently have Paul Turner High Rev pipes on my Shee. It also has Patriot Racing Ported cylinders (MX Port, Tats4life's old cylinders?), Noss head with 18cc domes, stock carbs, TORS removed, Timing advanced 4 degrees, Lightened flywheel, etc.
The bike runs hard as it is now, but feels like it may be missing something on the top end. I was considering swapping my PT's for some Toomey's. I ride mostly sand, so low end type power is not really a necessity. I'm leaning towards the T-5's pretty heavy, but still checking my options out.
