Adventure Bike Rider Forum

I do not know why people ask technical questions on this forum.........If robson just writes a SHORT sentence saying what he does not know, then we can PM him directly!!!

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)

It can't be any harder than taking bits of this
To fit this
To make this

There both honda, use your imagination (thumbs)
Same cc, same make, half way there (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?
