Iv got a 74 cl360 that runs, but feels like it won't open up. It is allso backfiring when i shift gears. Any suggestions?

 

bad fuel ? u check ur plug /wire possibly carbs need cleaning

 

New gas, and the guy i bout it from said he submerged the carb in some liquid. I guess i have to take the carbs off.
Runs good intill 4-5 rpm then falls on its face, then picks back up
around 6.5 rpm. New pulgs, one is brown now (looks like it was firing to early) and one soft black ash (to late)

 

Order up a carb gasket kit and a new float valve, take the carbs off and bring them to a motorcycle shop and have them dip them in their ultrasonic carb cleaner for a little bit (it will eat the gaskets up), take them apart, replace gaskets and float valve. When you're putting it back together make sure the rubber intake manifolds are still in good shape (not hard as crap), if they're in poor shape then replace them. Install everything, resync the carbs and ride.
