Re: THE TWTex XR400 Thread.

Drain tank also and start all over with new fresh gas.

Re: THE TWTex XR400 Thread.

Carb cleaned and reconnected, still no go. Best I get is a super loud pop followed by some smoke from the exhaust.

That sounds like symptom of a valve slightly open, check your manual compression lever/cable tension and adjustment for smooth operation. You may have an exhaust valve hanging open.

When you removed the pilot jet, Could you see daylight through it?
You said it ran for a few seconds then pops on subsequent attempts to start it - so we can assume spark.
So if you got a fresh plug, fresh gas, clean carb. It should start.

Some will cringe here but try a shot of starter fluid into back of carb. (Probably best to remove air filter cause if it pops back - as in tight or open intake valve - it may catch filter on fire with fluid) so be ready for that!!

Otherwise you may need to dig deeper and check compression, check valve adjustment.

Fuel, compression, spark - it should start!

Re: THE TWTex XR400 Thread.

Took the carb off, re cleaned it to be sure, got ethanol free gas, tried starter fluid in the back, still nothing more than a ringing ear from the bang I get about every 3 tries. Compression lever and cable are operating smoothly.

Re: THE TWTex XR400 Thread.

Only thing I haven't really toyed with is the idle screw on the carb. Would that be giving me any trouble? It's got the TM36 pumper carb on it, anyone have a guess as to how many turns out that should be?

Re: THE TWTex XR400 Thread.

When I bought my current XR4 it had been sitting for at least five-seven years. I could not keep it running for more than a few seconds even after multiple carb cleanings. Each time after cleaning it started perfectly then sputtered and died with any opening of the throttle. Finally my simple brain realized I was sucking something into the carb from the tank. Careful inspection revealed some flaky, white stuff in the tank. Cleaned it several times with a pressure hose and installed an inline filter. The petcock had deteriorated into almost nothing. Bingo!!! Never any ethanol since. Since '07 it has had less than 100 miles on it and still starts and runs perfectly with never more than three kicks.

Re: THE TWTex XR400 Thread.

Update: RUNS AGAIN!

Finally sucked it up and took it to a buddy, who noticed that I had disconnected the stator among other things when I took the carb off to clean it. Back to a 2nd kick bike.
