Gorr Big Bore Yamaha YZ 295cc & Wiseco Crank

Used 35 hours play riding age 53 owner. Looks perfect still. Gorr 295cc cylinder, head, piston, wiseco crank, three power valve pieces. All parts still look perfect after 35 hours of use. I would run a hone through the cylinder and put new rings on the piston and it should be like new again. But you don't have to. It is good as is. I might have new piston rings and gaskets also. I enjoyed this combo it seemed to add about 30% more power over stock. I think I used a smaller power jet to tune the carburetor. I can provide my jetting change information.
