I changed the stator, regulator, plug caps and plugs plus did some re-wiring on my GS450 last year. Since then, it's been nothing but problems. Went back to try and get it to work this week after taking a six month break. The bike started pretty quickly considering it had been standing for so long but then I noticed that only the LHS cylinder was firing. Checked if a spark was present and sure enough, no spark on the RHS. So I removed the ignition coil and found that the EHT lead had a break. Soldered it as best as I could just to keep on working on the bike while I buy a replacement. Put the coils back on today and the bike would not start. Tried another known good battery but still no luck. Both plugs are firing when I placed them touching the cylinder head but I'm not sure if the sparks are strong enough to actually start the bike. The plugs are gapped correctly. How can I tell if it is a weak spark problem? Could a faulty igniter cause a weak spark? Another thing I noticed was that I could not detect any smell of fuel from the spark plug hole after trying to start the bike for quite a few times. Is that normal? Thanks for any help.
