99 ZR600 EFI Trouble
I'm having trouble getting this sled to run right. I've thrown a bunch of parts at it, and it wants to run but not quite there yet. Here's what Ive got into it.
Throttle body boot
I've gotten it to start and idle, but it idles at about 2500rpm, backfires, and it takes quite a few pulls to get it started. When I'm pulling on it, it'll fire but won't stay running, and it gets progressively better as I continue to pull on it. I didn't have the belt on so when it was idling I revved it and it would sputter then pick up again. There were also sparks coming out of the exhaust but it hasn't run in 10 years so I think it was just some gunk built up.. Anyways, my buddy says 'let's put the belt on and see if she rips' so we did, but now it won't start up again. Barley even fires until you wait a while for it to cool down.
No start when warm, hard start when cold, and high idle with backfire... Any ideas?
