Rebuilt my first e50 and installed the 72cc airsal kit. I have been breaking in the kit for about 1-2 weeks right now and everything has been great so far. However, tonight, I was riding the moped home today in the rain and I cracked into WOT. About 3 minutes later, my moped started sputtering and bogging so I pulled over. My engine (at spark plug) did not reach more than 270 degrees Fahrenheit. It was kinda sketchy and I thought the piston ring got caught on a port (even though I smoothed out all my ports). FYI I am also running no air filter on my carb (if this has anything to do with the sputtering). I ended up riding the ped home at like 15-20 mph.
If anyone know what possibly happened just holla,
