At wits end

[fishman10]

i still have the occasional stalling issue,,,that seems to happen only when coming to a stop sign or redlight,,,,installed all the new parts supplied by csc,,ran a dose of lucas fuel injector cleaner thru it (per csc tech) adjusted the valves,, an also checked battery voltage per spud;s advise ( its fine),,,isnt anyone else having this problem? Could it possibly be something to do with the clutch safety switch? Oh btw the bike always starts right back up after a stall.

When is the last time you checked the valve lash?

I think it might be normal for some bikes with EFI to stall in this manner, occasionally. However, my problems disappeared when I put in a good battery, and adjusted the valve lash.

Mine has done it maybe 3-4 times in 3200 miles. Not enough to figure out why and not enough nuisance for me to worry about yet. It seems that if I've given it some throttle then chop the throttle off for a stop sign is when it has died. I can usually hit the starter button quick enough to save face though. rj

The new, Honda CRF250L motorcycles have fuel injection, and they exhibit the same behavior.

Today I once again checked my valve lash; it was 2,500 miles since the last inspection/adjustment. I am happy to report my there was no change in the valve lash for any of the valves. All four valves had the same valve lash I had set at the last adjustment.

I had an occasional stall for about the first 500 miles. It would just quit when I cut the throttle approaching a stop. Sometimes it would stall when first opening the throttle from a start. I got a bit used to blipping the throttle to help avoid this. But the problem seems to have cleared up, possibly after completing my first valve adjustment. My exhaust valves were loose -- roughly 0.15 mms or more than twice the spec of 0.04 - 0.06 mms. Once I set them closer to spec things got quieter and a bit smoother. And it's stopped stalling. But I can't be certain that the valve adjust had anything to do with the stalling.

i just did the valve adjustment last week,,,so only 200 miles ago ,it definately runs better since then..The intake valves were screwed down tight ,could this have hurt it? mine stalls 3 or 4 times in 100 miles just like others have said when coming to a stop or at a stop and trying to start off again.

Switch the key on and off, three times in quick succession, as described in post #17 of the thread linked below. Then watch for an error code.

i tried the key on off on ,,3 times an dont get any lights blinking in the dashboard,

The lack of problem codes makes me suspect the battery or the valve lash.

The valve lash is very easy to set too big, since the valve cover openings are relatively small, and bend the feeler gauges. As with my Honda CRF250X, I need to insert the feeler gauges from the opposite side, or I bend the gauges, and set the valve lash too high. Perhaps you might want to try my technique, and see if you get the same readings for the valve lash.

Me neither. Does that mean no faults diagnosed? Theres nothing wrong if you own a no fault Zong . rj

Perhaps that could be interpreted two ways. Do you end up with the key in the off or on position?

Indeed, one must follow the directions in the post.

...open and close the key for three times, namely, open —close—open—close—open the key, the fault light will come to a flash code corresponding to the fault.

One must also perform this procedure quickly.

If you don't get any fault codes, the ECU believes the EFI system components are in good condition. If you have a genuine problem, then the fault must lie elsewhere, with the battery, valve lash, spark plug, et cetera.

Please bear with my ignorance. To me, open means to disconnect a circuit, or switch it off. Is that what you're saying, or by open, do you mean key on?

It makes sense to me that the key must finish in the on position.

I didn't write the instructions; I copied them from a Chinglish manual at the following link.

Indeed, the key must finish in the 'on' position. You must turn the key on and off quickly, namely, on — off — on — off — on. If the ECU has detected a problem, the engine fault light will then flash a code, as described in Chinglish at post #17 in the following link.
