Hello everybody this is my first post and I am a new user. Just thought I'd introduce myself and show my bike. It's a fixie from Walmart the kind with the flip flop hub I put the sprocket on the fixed side and run the freewheel on the crank side. I like this frame because it's very tall and uses 700c rims and had room for axle tensioners. It has a SkyHawk Gt-5 from 2011 that came on a partial build I found on OfferUp along with a dellorto clone carb everything else is stock. It runs okay I can cruise 20-25 and top out about 35 the only issue I'm getting is it running very hot 300 degrees and up on a long ride and I'm not sure what to do about that I've tried a number of jets and fuel ratios the only thing I haven't tried is a different sprocket as mine looks to be a stock 44t or more. My crank seals are not leaking into the case and I'm not getting air leaks it just seems to lean out at full throttle. Thanks for looking
