hello everyone new to the forum . and have a few questions about my banshee . i bought it not running so i tore it down and discovered i had two different pistons in it one is a wiseco with a part #9439 67.92mm and the other one says 68.oo and that is it . my question is can anyone tell me what bore these numbers are? and also on the crankshaft i only see a 29L on the rods, and im curious to know whether there is a way to tell if the crank is stroked or not . thanks for any help in advance
