you did say it runs,albeit badly, in your first post.

if you access to a bike tech can they not sort it or at the least find you some cleaner?

Very badly. Without Quickstart only seconds at a time. I'm working on getting a tech here over the weekend.

Engine not idling, surging, hard starting, stalling
 

While you have the fuel tank off, check the wiring loom that runs there. Sometimes this rubs against the frame, exposing wires and creating all types of problems. There's a thread on that somewhere over here...

So I got a can of fuel injector cleaner with a courier, put the pump in a bucket of gas, with the injector connected with a pipe to the pump, and connected everything to a battery.

Now I don't know anything about injectors, but I would have expected a fine, powerful spray, like what I'm used to from diesel injectors. Instead I'm getting a very coarse spray, not very powerful at all. Without a pressure gauge it's difficult to say what pressure I'm getting from the pump, but it's very easy to hold the pressure end closed with my thumb. Most pressure then escapes via a coupling between the two halves that houses the fuel pump. Surely that can't be right?

The greatest sound ever, an XT idling. Well, the second best, the best is when it's revving. Apparently there is a second fuel filter, besides the teabag, in the fuel pump assembly. I sent the pump to the agent, who cleaned out that filter and also assembled the holder correctly, apparently I made a half-assed job of getting the o-ring between the two halves properly positioned. She runs!

Glad you got it sorted - and thanks for sharing your experience.
When you were running the pump an injector in a bucket of fuel, did you just connect the pump directly to the battery? How did you trigger the injector?

I connected both directly to the battery, being really careful to cause the sparks on the battery side, and not the bucket side. I was concerned about the injector overheating, but it remained cool for the entire hour.

The /"�&!!! gremlin is back. After getting the bike started, and after driving it for a short trip on that day, the ten started to huff and puff it's way down the gravel road a day later. All hopes that it would disappear by itself are gone again. At least it starts, mostly.

When it's cold, and I mean really cold in the morning or having stood still for six hours or so, it runs normally. But as soon as the engine gets hottish, after maybe half a mile, the misses and surges and mild backfires appear. Which leads me to think it may be the coolant temperature sensor?
