Thanks Elliot, W9 FTW!
Mid range feels good, a bit rich warming up but pretty healthy after that.
WOT w/ 90 jet 4-strokes for the first 10 minutes or so, after that it really blasts at WOT but feels lean like it has an air leak, but I've checked with carb cleaner... do air leaks pop up suddenly when you're going 40mph? Cause I can't find any leaks at idle. Honestly, it could be that I don't know what a 70cc engine feels like at full rpms, cuz this is my first kitted bike. But yeah, seems like if it 4-strokes for the first 10 minutes, and there isn't an air leak, it shouldn't be lean at WOT.
almost done, siiick.
