Xt660x cutting out ?
 

Hi all I've a x it's got 18k on clock , every now and then it will cut out on slow down , it's got microns on it and k&n , I may ride for 2 hours no problem then it will cut out but restart no problem, and sometimes not at all over a3hour ride ,
Any thoughts from you guys ?

Most of the time this sort of behaviour can be attributed to a low idle speed. Check that the warm idle speed is around the 1450rpm mark.

On X/R models you need to get a rev counter displayed in the bike's dash to set idle speed, so follow this procedure:

First set engine run/kill switch to 'off' (and ignition to off).

Press both 'SELECT' and 'RESET' buttons and then switch ON the ignition. Keep 'SELECT' and 'RESET' buttons held down for at least eight seconds. The dash then changes to show 'DIAG' in the display. Now release 'SELECT' and 'RESET' buttons.

Press the 'SELECT' button once so 'CO' shows in the display. Now press 'SELECT' and 'RESET' buttons again and hold them down till 'CO1' appears in the display.

With 'CO1' showing, switch on the run/kill switch and start the engine. The revs will now be displayed.

I'll give it a go tomorrow thank you for your help so far

One point I adjust throttle cable to up revs , it's not via computer?

You adjust it with the throttle stop screw (with red paint on it in my case):

Clockwise to raise idle and anticlockwise to lower. Make sure the engine is up to full operating temperature before making any adjustments.

I must say on tick over every now and then it seems to miss a beat , maybe me just looking for anything

That's pretty symptomatic of a low idle on any single cylinder engine.

I will come back tomorrow with more information, but sounds like you have answered my problem

It fluctuates a fair bit but turned it up 1/2 turn will see when out if any better
If not can I pick your brains a bit more

See how you get on. Just out of interest, do you know when the spark plug was last changed? A slightly off/old/worn plug can cause rough low speed running on singles.

You are welcome to pick what's left of them! ;)
