[QUOTE="El-Senor, post: 976308, member: 61664"] Hello all! New guy here.... I have 70 or 80 hours on my 04 CR250. I ride only trails and haven't really noticed any problems. I want to put in a new piston and top bearing so I bought the stock size Wiseco replacement 801M06640, the Wiseco top bearing B1003, and a Cometic top end gasket set. My bike has a few mods for trails: Phathead head (1 over dome) Boyessen rad valve and flange FMF Gnarly pipe and Q silencer Steahly 11 ounce flywheel weight Clarke 3.2 oversize tank Talon sprockets/ DID ert gold chain Kouba lowering link Renthal Fatbar Trail Tech computer DeVol rad guards Magura Hydraulic clutch and a W/C skid plate I run C12 50/50 with 91 octane at 32.1 with HP2 oil. I would like to have Swain tech coat the new Wiseco piston but I don't know if it will increase the diameter too much? All I've read here states that the Wiseco is universal for A & B cylinders and drilling the bridge holes is optional. If anyone has any opinions on the Wiseco/Swain tech, Drill or don't drill theories I would appreciate the help!! Thanx for reading...
