If you don't fix the spring when it goes "gronk" it will make the whirring noise of impending death.
Then it will look like this when you take it apart:
All the bits you see on the back of the flywheel are former spring.

it's a good thing I change the spring before
Good to know

It works like a charm

so! looks like i cooked my sprag bearing too, its got the horrible noise and the engine doesn't crank over yet the starter spins up. taken it apart and doesn't seem to be much wear that I can see, but the spring is definitely stretched.
I went to the local for the CR 19778 seal, they didn't have that exact one on hand, so supplied an "identical" seal of another brand. it might do the same job for what it was built, but the spring inside it is too large a coil diameter for my purpose! waiting on the CR 19778 to arrive in stock and hopefully it will save me a few dollars. ducati australia want $270 for the sprag bearing, the KTM equivalent is $140, the oil seal is $11-$14. lets see what happens!

Correct seal picked up today. Spring looks good. Will fit in the next couple of days!

Can confirm the CR 19778 seal spring is a winner!! Fits, sprag functions again, and costs two parts of fvck all - it’s only $15 instead of $270 AUD!!
