    Help! Poorly running 750k

    Okay, so after months of boards studying and not being able to work on my motorcycle I'm finally done and was able to dive back in. I replaced the insulator boots with brand new ones and changed the air filter as well hoping that this would help with vacuum leaks that I definitely had. It...

    Help! Poorly running 750k

    Thank you so much for all the feedback everyone. In medical school and boards are coming up so motorcycle work has slowed down a lot for me. As for the carbs all four were separated so I had four individual carb bodies, I removed the main jets and imulsifier rubes from each, the pump from my 2nd...

    Help! Poorly running 750k

    It entailed completely stripping the carbs down and spraying carb cleaner and compressed air through every hole I could find on the carbs to make sure they were clear. Also very carefully went over them again because the first time I took them apart I found whoever cleaned them before I bought...

    Help! Poorly running 750k

    Alright I pulled the carbs off and took a look at all the insulator boots. They're not cracked and are stiff but still squish some when squeezed. I put everything back together as carefully as possible and really tightened everything down and the bike no longer revs when sprayed with carb...

    Help! Poorly running 750k

    -Update_ So today I drained my carbs and put all new gas in. Warmed up the bike and checked my compression; 120 across the board, plugs are brand new but do look like they are starting to get some carbon on them, guess the bike is running rich? I adjusted my valve clearances, my cam chain...

    Help! Poorly running 750k

    Bought a 78 cb750k last year and didn't get to ride it (beginning winter). Went to fire it up this year and found it only running on 1st and 2nd cylinder. After much tinkering found it was bad coils and replaced them. Now it runs on all cylinders, but idles poorly, sputters, and dies as soon as...
