Re:Air/Fuel Ratio 1 Year, 10 Months ago  
Apparently my woes are not over. Took her out for a ride this morning, got about 2km from my house and she died while I was going down the road. Now it won't idle at all. Starts, runs for 20 seconds and quits. Can't even get it to run long enough to ride it home. Not entirely sure what to do now.

Have you tried bypassing the fuel pump?

No, not sure how either?

follow the fuel. out of tank other end of hose put a connector. disconnect carb hose at the fuel pump and join to the tank hose.

I didn't have a connector kickin around, but I disconnected the fuel line from the carb, and turned the ignition on and it definitely pumps fuel, and a good quantity of it.

Just weird that it ran awesome and idled awesome yesterday, and now today it won't run.

I can fire it up, and it will sit there and idle, real poorly, for a bit, and then it just quits. If I rev it up, it will idle up, but it coughs out the carb and tries to die.

When its sitting there idling, I can see a bit of fuel coming from the needle port into the throat. Not sure if that's normal or not.

Where is the idle at? Low or high? Air cleaner clean or dirty?

Hard to tell where the idle is at because it won't idle properly, but when I shut it off yesterday the idle was good. Haven't touched it since.

Air cleaner is clean, and even running the bike with it off doesn't change anything

No, it almost seems to run worse with the enrichener out. I tried with it all the way out, then half, and then slowly pushed it the rest of the way in, but still nothing changes

Perhaps a piece of trash broke loose in there and is now blocking a passage or two.
Remove the carb again and blow out those little passages with compressed air. All that will cost you is a little time.
BTW, leave the settings where they were when it ran well yesterday.
