actually it's like 15 minutes, this is called 15 minutes idle reset after some major changes.
ECU should adjust, to a degree.
so why do people bother to buy a ejk,,thingmy...and can this trick be used a previuosly used bike...i am coming from a point of complete ignorance in these matters

this is the common misconception by people who never ridden off-road, because when doing technical off-road we are quite often at the low revs.

Besides o2 sensor doesn't read air/fuel ratios, it just simply generates few volts when there is difference in oxygen level between outside air and gases in exhaust. That's it.

Just a thought for you crf250L owners don't any parts fit from the crf250x? Especially suspension wise, the x model has great suspension, must be a good supply of second hand parts as its been in production for over 10 years.
Worth investigating (thumbs)

I was wondering this too .. as I have some spares from my previous crf250x which I owned for nearly a whole week before I got sore with it, in arrears. I read that the mudguards don't quite fit, without cutting, and of course the engine is completely different as the L uses the old cb250 engine.

the front forks are narrower by a couple of mm so the tree thingies (fork clamps) would have to be changed, at least. I doubt that the rear shock would fit? the seats are completely different ... in short, its a completely different bike?
