I have an SP1, it runs or ran beautifully. My brother left it outside overnight. I tried to start it with the choke on, it started twice but died. Tried starting it over the rest of the day and killed the battery. Put in a new battery, it cranks over, kicks once or twice and runs occasionally but only on back cylinder. What could be the issue?
V twins are very spark plug sensitive.
Throw a new set in and she should go.
I had an Sv that wouldn't go, turned out the last owner had mismatched plugs in her.
A new set and she started every time.
