cb750k running problems

mattwrx
hey guys. I have a 79 cb 750k. it starts up and idles pretty good, but when im riding and it warms up it starts bogging and jerking then shuts off when I pull the clutch in... Im guessing it needs the carbs synced? Any ideas? thanks.

Try opening the gas cap first and listen closely. Your symptoms sound like a clogged fuel vent or fuel filter.
The ride IS the adventure. The destination is just to get gas!

Even though it is a new petcock, are you sure it is working properly?

Try replacing the fuel filter and pump. If that doesn't work it could be the coil packs.
