I'm new and need some help. I bought an R1 and can't get it running it sat for a few years before I got it. It wouldn't start and the harness is a little chopped. I found a few issues I have fixed but need help. Can I put an R6 wiring harness on my R1 if I put the computer and rectifier with it? Second it's a slow crank like my battery is dead but the battery is fully charged.
