I have a 2013 yz450f that I’ve just installed a wiseco pro lite piston and rings stock 97mm bore into and I’m have trouble getting it started. The bike ran great before he rebuild, it was for maintenance because I was blowing a little blue smoke/oil out of the exhaust as it was running. Anyway, Piston went in just fine, installed all new gaskets, set it in time correctly, and put it all back together. Went to start it and has great compression, good spark, and seems to be getting fuel and air well. But it still doesn’t even attempt to start. I’ve kicked hundreds of times to no success. Every 10 kicks or so it will pop loudly as if backfiring and shoot a blue flame out of the exhaust about 5 inches long. Can anyone tell me what’s going on?
