Time for new chain & sprockets. I'm happy with the ratio but are there any worthwhile alternatives to the OEM parts?

You can shop around for rear sprockets, but make sure you buy OEM front. There are lots of horror stories around.
Ask me, cost me R12500,00 to repair after trying to save R200 on a cheap front sprocket.

You must have been quite irritated with yourself!

What happened?
Sprocket stripped the "keys" on the output shaft.

The keys...  :imaposer:

anyone know the bearings sizes for
Steering head,
Front wheel bearing (found this , NSK #6906DDU2CG23 or probably just referred to as a #6906 bearing.)
Rear wheel bearing (found this, (KTM P/N 0625032067 Description BALL BEARING 3206 2RS1))


also , what fork oil would you recommend for a fat kid? should i stick to the 5w and add a smidge more, or go to a heavier weight and still fill up as required?

its for a 2009 White with black swingarm

Go to Bearing Man or the likes and ask for this

6906 2RS
3206 2RS1

Will be much cheaper than KTM. Just make sure they don't give you cheap Chinese bearings. ASK for SKF or FAG etc.

One of the main reasons that the bearings fails is that they get water and dirt into them, as well as lose their lubrication through worn seals. Make sure that you replace the seals amd use good grease.. the "expensive " bearing sets at KTM contain seals and all of the necessary bits to keep the ugly stuff out.. so when you compare prices, ensure that you add in the seals that are required...

The "good quality" bearings will last as long as if not for less time than any cheapie if the seals are defective..

Are you aware of the 15 min idle ECU reset/self tune of the ECU?

Try that first.

Okay glad you mentioned this 15  minute reset thing. I actually thought it might be a hoax. Is it a real thing? Anyone done it?

It's not a joke. That's how the ECU re-calibrates itself.

Do you have a shop manual. It's in there.
I wonder where that road goes? And that, has usually made all the difference. Appologies to Mr Frost

howsit guys

just some advice pls.  There is a 950 for sale that has idling and backfiring problems.  the current owner seems unsure of what's causing it, ranging from inlet valves to carb settings.  anyone have similar issues and how were they resolved?

thanks in advance!

So, do you simply start the bike and then leave it idling for at least 15 min?

No less than 15 min and no more than 16 min. Bike must be cold, on center stand and then you start it and let it run for the time mentioned, do NOT touch any controls or throttle.

So, do you simply start the bike and then leave it idling for at least 15 min?
