well I got it running better not perfect but pretty decent. I synced the carbs using the dead cylinder method, I know its not really preferred but it worked ok. then I played with the mix screws and I have my left cylinder at 2 1/4 turns and the right at 2 1/2 turns. that's where it seemed to...

so you don't think that the carbs popping out of the boot could knock the sync off then, right? I will do the dead cylinder method again when I get home tonight, but would you recommend double checking my sync before I start with the dead cylinder method? or not? and I think I remember reading...

alright I was thinking the same thing, I didn't think it would be right to have different floats settings. they were the same before and both plugs were burning the same, which is why I'm leaning toward my sync being off after my carbs popped out...I have measured/tweaked my floats both sides...

5twins that is what I was thinking, my sync being off, it was fine but I think when my left carb popped out it might have thrown off my sync.?? The left plug is rich and that's the cylinder that's backfiring, the right plug looks pretty good to me... I don't have electric advance

My mix screws are set at 13/4 turns out 1/2 less than stock. I have a set of the 32.5 jets but correct me if I am wrong I am still learning but if I am already rich on one side with my mix screws where they are would I need bigger primaries? Or should I just try adjust my floats first? And is...

1978 xs650 pamco, PMA, cam chain good, timing good, valves good. .30 pilots, 145mains, slide needle 2nd notch... carbs were synced, if not very close, both plugs looked the same (good). I had a flat spot off idle (lean) and slight popping when cruising. floats were set too low (27mm):yikes: so I...

yes they do, and i would try mikesxs.com for new springs.

Running it with a battery at 3000rpm I had a max reading on 13.8v at the terminals. Haven't tried with the capacitor yet but my guess it's shot, considering when i hooked a battery up to the capacitor it ran fine but without the battery it went crazy.

Thx for the reply pamcopete, I'm pretty positive it is wired correctly, I didn't have any problems like this until that wire let go but I did notice I didn't have the best ground when running hooked to just a battery, so I fixed that. I will try the capacitor again with the good ground. With a...

Bike was running good up until I stopped for gas, when I tried to start it I had no spark. I then did some searching and I found a wire came off my fuse panel and I'm assuming the wire that came loose arced on another fuse terminal and it damaged something. I checked for spark after reconnecting...
