Ah yeah, the sprag clutch only connects the crank to the starter motor when the starter turns (or not in your case) The engine is always connected to the gearbox unless the main clutch is disengaged or slipping.

All sorted now!

The flywheel puller required a fair bit of brute force and a good dose of WD40 and eventually came off. The puller bolt actually bent slightly in the process. The old sprag came out easily, and I could see the spring looked a bit tattered but all the blocks were still there with a little wear evident. The new sprag slipped in nicely and everything was back together in the 2 hours I originally predicted to perform the operation. How wonderful it is to have the right tools!

Thankyou all for your advice!

Anyone need a flywheel puller? :innocent:

Hi all. Anyone have any idea how much a srag clutch is going to cost me for my KTM 640? And I'll bet it has to come from Austria?

Last one I bought cost NZ$144, It was ex Austria, you might be better off trying to source one ex USA if you need it in a hurry. Have you tried a new spring?

Hi,

I notice you're in Perth. Have you tried the KTM & Ducati shop at Causeway? I think the KTM headquarters for Oz is based there.

I have a flywheel puller if you need to borrow one... I've now made Perth my home after 50,000km on the road on my 640.
