I just bought a 1974 honda CL360. The motor was actually replaced with a cj360 but I believe the engines and carbs are very similar. The main problem I am having now is the bike seems to be running bogged down. It will still ride and I can get up to about 50mph but it seems like there is very little power. However,every once in a while, the bike will randomly take off and run very strong for about 20-30 seconds. It shot from 50mph to about 75 really quickly. Then it will start to run with little power again. I have all of that'll I exhaust and air filters on. I just don't know what could be causing it to randomly start running really strong for short bursts. It has happened I'm both 3rd and 5th gear. I'd appreciate any help!! Thanks!
