I got got a 450 r I come quads I owned a few 2 stokes notting bigger then a 125 This compression is a lot different. I’m having trouble starting a bike if I empty the carburetor out let the bike sit and I turn the gas on the next day choke on it start first kick and then I’m able to get it started here and there maybe two more times if I leave the gas on and I come back to the bike in like 45 minutes trying to get the bike started again the bike won’t start, I don’t know if I’m slowly kicking it and I’m flooding the car I don’t think I’m hitting hard enough sometimes it has white Kimble exhaust valves and intake I don’t know what’s good with this bike
