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.

 

Pretty sure the stock is 64mm.

 

Thank you

 

In other words, they could have simply said its wicked fast.
