2001 ZL 800, low power and knock then dies
I have a 2001 Zl 800 it has flatside not efi. It ran fine, over the summer I would start atleast twice a month to run fuel through. I went on 2 decently long rides this year (10-20miles), and it ran and rode perfect. I went to take it out for the 3rd ride, rode about 1-2miles and it started dieing, feathered gas for a bit to keep it running then it died. Got it running and got it home(died again on way back), and started it the next morning and it now has a very loud knocking noise. The sled will not stay running without throttle. If you start driving it, it has no power but starts to feel normal with high speed, after a while it just dies again. I dont know what this is any answers will help. I can answer any questions. Checked y pipe, and power valves.
