  1. Bike Won't Stay Running

    Carbs and Fuel System
    Hello all, so yesterday I was riding home from work when I stopped to fill up on gas. When I got back on the bike to start it ,it wouldn't start. The starter was spinning just like normal, the voltage on the battery was good, petcock was in the on position. I couldn't seem to get it started...
  2. Oil in Radiator

    Engine / Exhaust / Cooling
    I have a 1986 VN750 with what appears to be straight motor oil in the radiator coolant reservoir. I am wondering how bad this is. Do you think just draining the oil, flushing, and refilling will take care of it? Thanks for your thoughts. The rest of the story, if you are interested. I had...

  5. Changed coolant, gauge doesn't register

    Engine / Exhaust / Cooling
    So I changed the coolant. I never could get anything to squirt out the bleeder valve under the tank though I put 3/4 a jug of fluid in it. I did rock the bike back and forth on the center stand so any bubble would get released. I rode to work yesterday, it was 39 degrees in the morning and...
  6. How long does the radiator fan stay on?

    Engine / Exhaust / Cooling
    I just purchased an '86 Vulcan 750... love it!... but has a couple of issues. The fan is kicking on, and making a noise that sounds like an electrical 'buzzing', and keeps going for quite a while. I actually disconnected it to stop it so it wouldn't drain the battery. The temperature gauge does...
  7. Refilling coolant

    Engine / Exhaust / Cooling
    Hello all - My radiator drain plug decided to end its life, was leaking badly, and I am now going to have to replace it. That's no big deal really. My question is, after the radiator drains out from taking the old plug out and putting the new one is, is there any 'easy' way to refill the...
  8. Hyperlube and 20 degrees cooler

    Engine / Exhaust / Cooling
    Changed my coolant and added Hyperlube's 20 Degrees Cooler to the mix. To work out the bubbles, I let the engine run at high idle (1500 rpm) for 10 minutes w/o the radiator cap on and the fluid was hot. Shut off the engine and let cool for 20 minutes (+ or-,) capped the radiator, and started up...

  10. Coolant Pipe Leaking

    Engine / Exhaust / Cooling
    I have a 1986 Vulcan 750. I recently pulled the motor to fix some timing problems. After reinstalling the motor, I have had nothing but coolant leaks and issues from the right side cover and that P.O.S. coolant tube that goes from the cover to block. I ditched the stock felt gasket and have been...
