I'll be PMing about that spring in a moment. Thanks, btw, for that guide on the tensioner--very helpful. Any ideas on what's causing the spring to pop out in the first place?

That spring pops out cause the tension adjuster has gone to its maximum extension. You can't just put in a new spring and away you go. Guide wear and chain stretch combine to over extend the plunger.

How many miles are on the bike?
What year?

Things you'll want to look at are...
wear on the rear guide,
stiff links in the chain,
any damage.

the rear guide can be replaced w/o taking the head cover off
but to replace the chain, you will need to remove the head cover.
both can be accomplished with the engine in the frame... most of the time.

When you check the chain, you're looking for stretch over 21 pins. Check several places around the chain. Also take and move every joint. If you feel one sticking, repeat ONE, I'd replace it.

Wear on the guide will be pretty obvious, there'll be a spot on the chain that's been eaten up. whereas most of the guide will be smooth and shiney. Quite common for the guide to have cracks in it. You can replace it later w/o taking the head off, but ask yourself do you want to tear it down again. and a worn guide will extend the plunger 3 or 4 mm's.

Mine's in the 1/3 as strong neighborhood and it wooks just fine and maby the cam chain will last longer this time ?

How did you do that? cutting a 3rd off reduces the preload, but increases the spring rate.

A bit of an education on spring lingo & spring basics would be handy.
Any links to what youre saying would be fine w/ me.

I agree that a softer spring would be okay. Im thinking the ratchet teeth are too close together, too.
