Hi all, It had been a while since I started the Buell but I've had a few issues getting it going again. Firstly I could not get it started at all regardless of what battery I used. I did a bit of digging and found that it could have been the grounding wires so I cleaned them up (just between the battery and the frame) and that seemed to finally allow me to start the bike with the jump pack but it may have been a coincidence because it wouldn't start again doing the same after I came back from a 30 minute ride. The check engine light kept coming on at high RPM then disappeared as soon as the RPM dropped. The bike seemed to run completely fine once going. I know slow cranking is a bit of a characteristic of these bikes but it seems a bit excessive at the moment. It really seems like it's struggling to crank the engine over. I put up a video to show what I'm experiencing so i hope that can give some more clues as to what the problem is. I'm using a fully charged, almost brand new jumper pack. I thought that if the check engine light is related then it doesn't seem like it would be the starter itself so I'm thinking maybe it's an electrical issue? Is there a way I can create an auxiliary ground using a a jumper cable or similar?
