How's it going everyone, here's the issue that I am having. After I installed a 100cc Big Bore Kit on my IceBear Mini Max (50mm Piston/Head/Cam and Aftermarket Ported Carb 20mm) Everything was working great! Bike was awesome, happy with the performance upgrade. However, it appears I did not add enough oil/cheap piston rings in the kit may also have burned oil, resulting in the moped overheating to the point where it died out on me. After getting to my place I added oil and started it up. Burning lots of oil from how much smoke was coming out of the exhaust, so I figured the cylinder walls may have gotten scorched. I essentially rebuilt the engine replacing the head,new cylinder wall, new piston, new rings (clocking them correctly and facing correct orientation), new gaskets. After attempting to start again it was still smoking excessively. So I replaced the valve seals in case they got damaged when the engine overheated, cleaned up the valves, all good, made sure the timing was correct for the engine. And still when I start the engine it starts to smoke excessively. There is not too much oil and I'm using 15-40w. I'm completely out of Ideas as to what is causing this issue, any suggestions would be very appreciated and I'll answer any questions in case I left out any Info. Prior to the Overheat, the bike ran great with no issues at all, little bit of smoke but didn't think anything of it, nothing like the cloud that it is now. Thanks in Advance.
