chain tension on Katooms

[rollingp]

For those who dont know watch your chain tension on ktms.
Forget about the manual.
Take off the shock and while the bike is on the stand raise the swingarm making a note of where the chain gets tight.
Use this as a guide. KTMs need more slack than the average
jap bike.
A good rule of thumb is three fingers just behind the chain
guide on the top side of the swingarm,
One reason some guys are breaking hubs and going through
sprockets is the chain is binding.
This also screws up the rear suspension action.
Even if you get a little chain noise dont frett.
It wont hurt a thing unless it is super loose.
This also mkes the rear wheel bearings last much longer.;)

Servus,

When using the 'correct' slack there is a lot of noise and the possibility that the chain hits the frame beneath the swingarm axle. KTM has a fix for this, but it only comes stock on the 2002 SX models. Instead of the lower chain roller they use a chain block which protects the frame and cuts down the noise. Works fine on the EXC models too :)

Your right on the money Michael but the new set up sure doesnt last very long.
I bought the 02 520 in Nov and the guide is ready to be replaced.
They are allot less noisey.
