ok I am a NOOB to atv's, but I recently bought a 1996 Yamaha banshee. The papers stated that it is ----------> "Trinity bored 82.5mm and port polished, wiseco power lite pistons, shaved heads 210psi is the compresion, hot rods crank, 42mm kehin carbs, vito reeds with equalizer tube, barnett dirt digger clutches, ball bearing clutch lock out kit, 110watt ricky stater with timing adjustment plate, k&n pod filters, vito fat bastard pipes, works gas shocks, new plastic by laker customs, motion pro twist throttle
can someone please tell me how much this atv is "bored over". I am a Noob, thanks so much for the help.

 

Unless it's a misprint or has a big bore kit shows to have a 64mm standard bore for the cylinders on the Banshee.Shows 66.5 max over size bore at Wiseco.
