I have a 1971 Honda CL175 that I have been working on the past couple months. I've gotten to a point where I'm stumped and I need help. After the bike warms up on a ride it seems to drop to one cylinder or lose power. I can stop for a little while and start again and its fine. This led to think it was the coil. So I replaced the coil thinking this was the problem but it still does the same thing although it does run a little better with the new coil. I also replaced the condenser while I was at it. Before this I went through and cleaned the carbs, adjusted the floats, cleaned the tank, and checked the points and timing. The bike runs fine when its cold, its just after a little riding when it acts up. Any thoughts or ideas would be much appreciated!
