Hey guys, I finally got my carbs sorted out but now I'm having another problem that I'm hoping someone can point me in the right direction on.
The bike is a '75 with '79 carbs. I went for a ride and the bike ran great for the first 7 or so miles. Then it started to sound like it was going to quit for a while and finally it did quit. I suspected clogged idle circuit but put new plugs in on the side of the road and got it lit. It was tough to start but it did run. Again, it idled but sounded like it wanted to quit.
Here comes the problem. From this point on the bike started to backfire out of the right exhaust when ever I closed the throttle and the engine was between 2400 and 2900 rpm (i.e. slowing down for a light, etc.). I tried to adjust the mixture screw slightly but ended up with it back where it was. I also checked timing with a light when I got home and it checks out. I lubed the auto advance rod today too. Finally, the spark plugs were pretty white when I pulled them but not sooty. I can post pics if that would help. Any suggestions on what to do next? Weak spark/ compression?
