Hey guys. Here’s what happened. Driving home a while back, 6th gear pegged for about 30 seconds, then wheels lock up and I come to a skidding halt. Tore it down, and nothing was moving, pistons, crank, kick starter, nothing. Oiled the cylinders, played with the crank and eventually everything was rotating as it should, in neutral. Once in gear, no movement again. Got the wheels to rotate in gear eventually, compression good, all seems well. So the whole quad seemed ok aside from some internal scarring maybe that I couldn’t see. I never went deeper than removing the head aside from the case covers and external stuff. Put it all back together, flushed the case three times with oil, and nothing came out. Clean oil, no metal. I said “this thing is ready to run”! Put it all back together with new gaskets and seals for the head(pro-design). I fired it up, and instantly knew something was off. It has a very scary sound coming from the case. It sounds as if it’s rotating with no oil. Just like a hollow metal whirling sound. A lot of white smoke coming from the right pipe and none from the left.(crank seal?). Kick starter actually binded up once during the startup but not again, but it’s never done that before either. I was pissed after all those hours of wrench time so I said hell with it and took it for a spin. She still pulls hard, just as hard as before. Seems to run tip top, pops into neutral good, hits gears good. But that sound is still there and so is the smoke. I’ve parked it until I figure this out. It’s a fully custom banshee from the frame up and I don’t want to blow it up. I won’t get lucky twice lol I assume it’s a stock crank, I built the engine from the jugs up. Never had the cases apart, I bought a complete bottom end. I’m leaning towards a crank seal or something in that area. Long post, I know. What do you guys think?
I just had purchased a banshee recently. The right side pipe smokes a BIT more than the left (yes it is a noticeable amount, no its nothing crazy. it also has no smell). It leaves the right silencer wet and it also spits oil were the expansion chamber and silencer pipe meet. It smokes more at idle when cold but not so much when it warms up...It spits oil regardless of temp. The right side pipe does not warm up near as fast as the left. The left side seems to "ping" alot harder than the right as well. Right side plug was wet/black when checked. I know no one here can tell me just based off this what is going on.... but im looking for educated guesses and points in the right direction.... Just praying its not a crank seal on the right side......
