Still running points?
If so, toss that shit in the trash. I spent a full year dialing in my carbs, redoing the points, new points, redoing the carbs, etc... to try and get mine running better. I even thought "Man, I really SUCK at this" and paid another well known shop to adjust the points and get the carbs right. No better. Bought new coils, new points (3x) and condensors, rewired the bike, etc... i was totally convinced my problem was carbs, but I could never get them dialed in.
Then, in a last effort to keep the bike, I decided to get a DynaS ignition for it, and ALL my woes went away immediately - I still have to get the carbs dialed in just right, but instantly the bike ran 100% better. That was after 3 points changes, and god knows how many times I adjusted them. The bike just never ran proper with them
