I bought a 1988 GSX-R750 a few months ago, and so far it's been giving me quite the headache. So far I've redone the brakes, master cylinder, and rear shock. I took it into the shop a few times but the carbs were still leaking and the bike was stalling when stationary. I took it to another shop and right away the mechanic said one piston isn't firing. It has new sparkplug wires and he tried a new plug but it still wouldn't fire. The carbs were taken off and opened up, there was a brown film in them along with remnants of carb glue. They're telling me I need new gaskets, o-rings, float assembly, and float needles. Will fixing up the carbs solve these problems? Are there any other possible reasons? Any advice would be greatly appreciated, as I'm running out of cash to fix this thing! Thanks.
