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?

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).

Finally@Bike Work...

OMG...

I finally did the Sprauge fix but something else is wrong now???
Yes I'm slow @ getting anything done!

Pulled everything off & out last year, but had to pack up the garage for the season!

...9 months later and here I am...

buttoned everything back together and waited for some guts to hit the e-start. Guess what happened?

Nothing, LOL.

Well that's not true, starter motor got REAL hot, headlight went dim...

Stopped at that point and decided, I must have assembled the sprague assembly backwards, the new spring was installed and all the odd shaped pieces installed with somewhat smooth finish.

Checked this afternoon (yes I pulled all the covers off again) and it seems to match the picture in post 1 (way up there) and I'm (yes I'm not very mechanically gifted) wondering what I've screwed up???

You all must be laughing your A55 off at me today...it's ok, it's good to laugh..LOL

The main gear that inserts into the sprague assembly, is turning in only one direction, that is (excuse my poor mechanical lingo) clockwise turns shaft (if the shaft key was removed) but counter-clockwise turns freely.

ok...when your all done laughing...tell this sparky where I went wrong!

Duh, you do realize if you woulda bought an XRR you wouldn't be having this problem!
When you figure it out you'll be happy to not be kicking it.

Did you try to pull in the compression release first?

I'm sure a real mechanic will be along shortly.

Good luck
