To realize this is the tightest the chain will ever get, over the suspension travel, imagine the rear moving up or down from this aligned position. Since the swingarm pivot is between the sprocets, you can see that the distance between the sprockets (labelled 24" in the above image) will decrease to less and thus the chain will become more slack.

Hence, if the chain slack is set to a minimum acceptable value, just loose enough to not be under tension, in this case about 1/2" of play in the center of span, at the longest distance between the two sprockets, as above, then the chain will be properly tensioned for full suspension travel. It should be not sloppy but not under any tension in this position of max tightness.

It should not be guitar string tight but shouldn't have any slack. Once you set it at that point you can check the slack measurement when you are off the bile and you will know where to set the slack when you are not compressing the suspension.
Another way is to pull the shock out of the bike. Send it out for new oil and a service, then move the swingarm through it's arc (with the tire and chain installed of course) and measure it as described above. After shock is reinstalled, put the bike on the stand and push the bottom of the chain up towards the bottom of the swingarm. Take a photo of the resulting distance and stick it in your owner's manual.

Hey, for you guys riding in Colorado in the summer, it wouldn't hurt to read up on a bit of lightning safety. This paper on backcountry lightning risk management is excellent:
http://www.nols.edu/nolspro/pdf/Ligh...rintmaster.pdf

For example, did you know that 40-50% of lightning fatalities are due to ground current and only 3-5% a result of a direct strike?

When hiking July and August you generally want to be off the summits by noon. There's more leeway when riding because you can get down a lot faster or sometimes go around bad looking clouds, but you're still exposed like a hiker.

When you're above 11,000 feet and the lightning starts... hooooollllyyyyy shit!

When michael.brat came through, he had a pad on his seat that made him more comfortable. He also got me one kindly. Denis used something that involved jugs of water... http://advrider.com/forums/showthread.php?t=494589

Sorry if I made it sound too easy, but most everything is easier to read about than do.

I get on the right side of the bike, pull it up off the stand and balance it, press my chest into the seat, with my left hand grab the swingarm near the bolt, pull up on the swingarm while putting my weight on the seat through my chest, and checking the tension/play with my right hand.

I can do it a little easier now than the first time I tried it...

True, except that you never studied anything that cool, except of course fermented beverages and female anatomy.

True, but those two almost caused me to fail out!

The Harbor Freight website lists the price as $89.99, but my coupon indicates the price is $69.99. This motorcycle lift is heavy; it almost weighs 70 pounds. However, if you have the shop space to store it, you might enjoy buying this motorcycle lift this weekend, and saving $50 off the regular price.

You're not making me spend anymore money Spud, because I already have one (BTW, my tire changing stand showed up yesterday). I bought a Craftsman like this a few years ago and it is identical the HF one. I like it a lot, though, as you say, it is a heavy mofo.

I'm sure you will enjoy your tire changing stand, Teach. Here's another nice video on tire changing by Jay Clarke.



The tire changing stand allows you get up off your knees, and stand on your hind legs, like a man. That stand might be the best $85 you will ever spend.

I'm probably late to the party, (been at work all day) but reading this I wanted to share that at 300ft stock pipe/UNI/snorkel removed I tried a 58 pilot and it was so rich that when I slowed down to make a turn to another street and pulled in the clutch, the bike would die, so am surprised yours can run so well at such a high elevation maybe your pipe is really making up the difference?

We were with several locals and had been warned. One of the bikes was having issues and we got stuck for several hours up there. Never saw any lightning but I was very worried. The sky was black right over us and I was glad to get going for sure!

We were dodging that stuff the whole time we were in Colorado last time. Afternoon storms can really come up quick out there.
