I believe somewhere above was said the four M6 (8mm) should be torqued to 8nm

Please! stop calling the bolts M8. They are M6. The number refers to the thread diameter in mm. NOT the bolt head size. I'd really hate for someone to skim-read this stuff and try to torque an M6 up to M8 values.

Most M6 are 10 Nm.

So finally had the time to pull my flywheel off to inspect sprag clutch and it is definitely my problem... The spring is visibly stretched looks worse than loisus...
I was wondering tho if it would be OK to run the bike without the sprag installed back onto the flywheel as I'm still sourcing the oils seal for the spring...first one I bought was their skf#19993 interchange part but the spring was too thick ....I have on order an skf but have to wait a week and I'm jonesing to ride.
Haven't been able to ride cause kick start was turning starter motor and all and my quads are just not big enough ��

I'm about to tackle this project on my '02 640Adv. I just wanted to confirm that that it's okay to use the bolt from the front of the engine to lock the crankshaft in place when removing the flywheel?

And, will I need any special tools besides the flywheel puller?

No, the 02 has the newer ignition with a high flywheel torque value. Using the locking bolt may damage the crank

I can't get this 24mm nut off! This is reversed threaded right? I went at it with an air gun and it's not budging. I expected it to come right off... any advice?

I'm wondering if there might be some red locktite under the nut.

Yes it is reverse thread.. You may need to try a different impact gun, not all are created equal...

If I have a tough time to crack something with my craftsman air impact I just switch over to my big electric powered impact tool and it usually has little trouble spinning it off..

Yeah. I tried my cordless impact and the pneumatic. Nadda. I think I might push the bike down to the tire shop a couple blocks away to see if they'll give it a "shot."

Try a little heat then hit it with the impact again. 200 degC is enough to soften Loctite, a heat gun will do it.
