Answers:
- Gas:
That Bendix has been on there for a while. It's probably leaking air at both throttle-shaft seals and chances are you have air leaks at the intake manifold o-rings. Fire it up and spray a little WD-40 on the throttle shaft seals and see if it changes rpm. Same thing at the manifold clamps, but wait a while after you've sprayed it at the throttle seals, first.
Electrical:
1. Check your plugs for carbon and correct gap.
2. Check the ohms resistance of your coil. With a point setup it should be from 3.5 to 4.5 ohms.
3. Pull the point cover and your point plate and check the condition of your advance weights. More than likely they're worn out at the post support and the whole assembly needs replaced.
4. If you can't remember the last time you replaced your points and condenser...then do it anyway. Points are perfect the day they're installed. From that day forward they're on their way out.
5. Check your battery for condition and charge. Battery should read over 12V. Batteries rarely last more than two riding seasons.
6. Check your charging system. With a full charged battery, start your ride up and check the voltage at the positive post. At 2000 rpm it should read 13.5 to 14.5 volts. Any less and it needs further testing.
