Hey guys,
I am in need of some help! I would really like to get to know motor[cycle] mechanics more by doing it myself, but I think I need help on this one.
Here's the story: (1975 Honda CB360, 10,000 miles, daily rider for the last 1,000 miles.)
One day, riding home from work my bike doesn't react to the throttle as it should. I noticed I was missing a lot of power, but I didn't feel/hear a misfire. I rode it slowly down the rode and finally pulled over. I revved it up to 5k rpm or so and it seemed a little slow, but fine, hitting on both cylinders atleast. I slowly get it home and ride it the next day. Same problem. Seemed to ride fine the first few miles then I lost power again. It idled fine at the normal level. I head home that night and it is definitely only firing on one side. I check the plugs, one is black the other is fine. I changed the plugs, start it, same issue. Clean the plug, change the oil (not filter) with a mix of Marvel Mystery oil and some good Shell Rotella. I did this in case a valve was getting stuck or it just had some old oil as I had never changed it. No luck, same problem.
I have Tony (MrDontPlay) come try to help me check points and of course the soft screws on the covers were butter and I stripped them to hell. Couldn't get them off. Ordered a new bolt kit. Still could not get the covers off, so I get frustrated and take it to Twin Motorcycle. They keep it for 11 weeks, 10 more than they said, and after harassing them enough they get it "done." They supposedly boiled my carbs, put in a new slide, a new accelerator pump, and sync it. I pick it up (in rough shape), but it rides home okay. It backfired, which it has never done before. Backfired all the way home, figured it was just some tweaking I could do to the carbs. I try to ride the next day to work, get it out, takes more kicks than normal to start, and once it does I let it warm up for a few minutes. Get on and head down the road only to find that I have the exact same power loss I did before. I'm pissed I missed the best riding season because Twin could not get to it, and then proceeded to not even fix my problem so I'd like to do it myself with some help.
Does anyone have suggestions/advice or time to come check my bike out?
Any help would be appreciated! Thanks a lot.
Joe
