5-0 Bait,
Take plenty of pictures, wish I would have done a better job when mine was apart for the benefit other inmates.

I understand that different year LC4 engines require a different magneto puller in order to get to the sprag and fix it. Can anyone verify that this part number: 58429009000 is correct for a 2001 640 Adventure?

Brad,
That's the number for the puller I used on my '02 640 adventure.
I own it. Pictured on the previous page.

Want to borrow it?

That would be awesome. Let me know how to handle logistics.

Brad,
First swear an oath on your Owners Manual.

"KTM, grant me the serenity...."

Send me a PM with your address.

I will mail the puller to you, you pay me the postage and mail it back.

I swear, under penalty of flogging................

By the way, I killed a printer by printing out this damned manual. Would have been cheaper to source one on fleabay :)

Maybe someone will have an idea about this here:
Last winter, my bike got rebuilt, the whole shebang, crank bearings, piston, cylinder hone, etc. I took the starter clutch out and tightened the sprague clutch spring, and stopped the screeching noise it would usually make, too. So the bike runs great. Also, rebuilt the carb with new parts from Derek. So the bike runs great, usually starts with just a couple kicks. . . . but the damn thing won't start from cold on the electric start. Once it's warm, the electric start will fire it right up. And the weird thing: the starter turns the bike over just fine, it just doesn't fire up. Probably a carb issue and not a starter issue, but maybe someone has an idea?

Oh, and I'm also running the Denso spark plug that Derek recommended, sometimes I wonder if the spark isn't quite strong enough when the starter motor is working. . . .

Any ideas?

Slack,
Last few posts probably a good place to start.

Yeah, I've been following that. I think you're right, that's where I'll start: I mostly just reset the carb to previous settings when I put it back together (like I said, once it's running, it's great. . . . wheelies in third, and 50mpg all the time).

perhaps you should replace that sprague? thats where I would start..
