1999 900 won't start after low-speed wreck
I've got a '99 900RR that was in tip-top shape until I wiped out in my front lawn (grass was wet, I was stupid, my dad was watching from the living room couch, it was awesome). I was only going about 7 mph but managed to break the brake lever, windshield, and crack a couple fairings. Immediately afterwards the bike would start but sounded like it was only running on 2 cylinders or starved for fuel or...?
That gradually turned into not starting at all. It turns over and it sounds like it's trying to start, but never grabs.
So now I've got it in my garage, partially disassembled, and am trying to diagnose the problem. I've verified the following:
1. Fuel flow from the gas tank. I hooked 6' of fuel and vacuum line to the tank sitting on a bench and when I run the starter I get fuel coming out all the way to where it branches out into the carbs.
2. Spark. Hooked a new spark plug to each wire, grounded to the frame, verified that I get a nice spark
3. Alternator. Nothing's knocked loose inside, stator and everything look good.
4. Pulse generator. Again, nothing knocked loose inside.
5. Vacuum. I've gone over all 30' of vacuum hose and don't see any obvious leaks.
Any tips are greatly appreciated. I don't even mind if you poke fun at the fact that I wiped out in my front lawn. I've got a Clymer's but it seems to be kind of half-assed, can anyone also suggest a better manual?
