Sorry I'm frustrated but let me elaborate alittle more. So I did the rebuild has brand new crank and bearings and once I put the cases together the crank seemed stiff and not wanting to spin freely so I banged on each side of the crank and did nothing so I bought new bearings again and tried it all over same thing. I said screw it maybe that's just how it is finished the build with a brand new weisco piston started right up took it on a quick ride 3 times and let it sit for a few days and today I started it let it idle to warm up heard a pop it shut down and now won't start. So what happened or what did I do wrong?
