Wibbly , bravo on the old school style!
OP, "bump start it", is good advice.
you'll need a couple of friends, or a steep hill.
these bikes need a stout push to get them started...!
watch youtube vid's to learn how, and try it ?
When the plugs come out, you'll be able to see or smell the gas going into each cylinder. Then you can test the plug while it's out.
Careful when turning the engine cuz I once got sprayed in the face with gas. Also, make sure you touch the plug to a ground where it won't get hit with fuel.
if the pump is priming and it's cranking, chances are it's trying to start.
maybe you fouled your plugs pretty badly.
before going through the pain of pulling them. try bump starting it. the starter motor doesn't turn the engine too fast, so a bump start can often help.
i'm just giving you the easy options here. diagnostics can get miserable so it's best to start with the easy stuff.
Thank you. I attempted to bump start the bike today and it did SOUND like it wanted to start, but it never did catch. I got a good run (bike got up to 10-11 mph each time), tried first, second, third. None of the gears worked for me. There was a distinct smell of excessive gas coming from the bike the first few push starts so I'm guessing I knocked some gas out.
After wheeling it back to the garage I tried the WOT trick again and still nothing.
Could it be really badly fouled plugs? If so how did my bike go so suddenly from working to super flooded? It doesn't add up at all. I've pulled the radiator off. I'll either get to the plugs later tonight or early tomorrow and take a picture of how they look.
In the mean time - any other things I can check? I checked the PGM-FI fuse, the fuel cut off relay, and the hacked-up replacement grounding thing I made for it. Everything seems okay. I can definitely smell gas now so the injectors are probably fine. I'm just not sure how the engine flooded... aside from cranking it too much when it didn't want to start (by accident) - it still didnt start initially after sitting for a week. It just doesn't add up.
EDIT: Are you suggesting with the plugs off I kick the back tire or something to get the engine to turn and try to force the gas out?
