Joel swung by my house in Oakland,CA on his way to Oregon late last year on this bike. Truly experienced XL600 guy here to be able to pull stunts like switching heads out, carbs, seeing how they go...shit. can't imagine.
Please indulge me with my XL-600. I'm taking it backwards in time in one smear, and then pulling it towards the future in the next:
Oh yeah, as you will find, Adam, your chain is too tight. It should have the most slack when unloaded like it is in the photo. When the suspension is compressed, the chain tightens, so you should adjust it so that the chain still has a little slack when the suspension is bottomed out. A few minor tests should get you in your comfort zone.
Not that you will be riding anytime soon.
