What causes vacuum caps to pop off?I cleaned my carbs again and installed them back on and started the bike.It warmed up easier and faster than before and i heard a noise and saw a vacuum cap come off rather forcefully after i gave it throttle.What causes this?Also where can i get replacement caps that fit more snug?

I have spring steel bands on mine to hold them down petty sure it's factory. auto parts store should have a pretty good selection of caps.I hate signatures. Too many cars and Bikes to list here. -

Engine backfire will cause the caps to blow off. This shouldn't happen once the carbs are properly adjusted.2H7 (79) owned since '89
