I have a 1980 cb750c. I got it from a guy for 575 dollars and he told me the carbs needed cleaned. Cleaned the carbs and found a vacuum leak. Got new boots and now there is no vacuum leak. The problem now is that it doesn't idle very well and if you rev it it will hang up at about 5 rpms and won't come down. I tried turning the idle down and the bike just dies. So I'm not sure if it's just a carb sync problem or if there is still a vacuum leak somewhere. If anyone can give me some advice I would really appreciate it! Thanks!!!
