I just bought an 1985 Honda Rebel 250. The seller has the engine started before I came to his place.
When I got it home, I try to start the engine again, it didn't start, then I found out that the gas was set to off and the kill switch was on, then I corrected those problems and I could get it started. (newbie problem)
At first, whenever I start using the throttle, it stalls (carb problem?). I let it run for a little bit, then put some of the fuel injection cleaner (which I bought for another bike) into the gas tank (about 1 oz), then let it run for a little and I can use the throttle just fine.
When touching the mufflers, I found out the left side is cool to the touch and the right side is hot. Checking the engine, left side is cool and right side is hot. Both side has sparks.
When I pull the plug on the left side, the engine still runs the same. When I pull the plug on the right side, the engine dies.
I don't know where to start, please help, thanks.
I would first try swapping the coils and plugs, if still no fire on the left side I would check compression. If the bike sat with the intake open you may have something blocking the intake on the left side and no fuel getting to the left cylinder. Maybe a stuck valve or broken cam, hopefully not a busted rod. Should be easy to troubleshoot with the engine in the frame, the valve cover is easy enough to pull. Hope this helps, Chef

I tried swap spark plugs, coils and have the same result. I took it out today and it ran just fine at 35 MPH, didn't try to run faster.
The problem now is the left side running cold when the right side is hot
Remove the left spark plug and I still feel the puffing
