I've tried all the cheap parts and had to conclude they're uniformly BAD! Read the Amazon user NEGATIVE feed-back comments, for example, and you'll get a feel for how bad the cheap carburetors are! Even the jets are bad (they're not sized). I've tried cheap starters, too, and most work, but they're noisy and not totally dependable. I use them because my Kymco has a kick-start. Not recommended if you don't have a kick-start. Cheap gaskets mostly work OK. Cheap belts are OK, but there's no real deals on belts. Cheap exhaust pipes get all rusty within a few months. Cheap tires wear out fast. I've even used cheap gy6 engines, which work OK for maybe 10,000km, but the crankshafts break at the flywheel end. Cheap mirrors are awful - they're too small and they vibrate. I'm now trying to stick with Kymco parts but, yes, they're expensive.
