Agree. Pretty. That's some nice work there. I'm always in awe of the beauty of machine work. This craft took the USA to the moon and back. It's sad that we're now tolling out everything to China / India / Dumfukistan, sacrificing quality for price and disposability. Then again - does a hammer need 0.1mm tolerances ?

More power to ya' in your endeavors. (and lose the orange... ).

Those are very good rough percentages to start with, spot on.

Usually you set the race sag and if your static sag isn't right, you have the wrong spring. Adjust accordingly.

After setting race/rider sag if your static sag is too little, you need a heavier spring.

Sounds counter intuitive, but if you reason it out, you'll come to the same conclusion

In other words if you have to crank in way far to get the correct race sag. your bike won't settle the right amount when you aren't on it. With a heavier spring you don't have to crank in as much preload and the bike will settle farther, as long as it isn't too heavy..

I'm not sure its excessive with the right spring, but links are there to modify the leverage ratio that the axle applies to the spring. OTTOMH, I've think I've seen the DR link quoted as 2.8:1 AVERAGE. This is the interweb though But it doesn't start or finish at 2.8 though. Some links have rising and some have falling, and some combine rising and falling changes in the ratio as they go through their travel. I haven't got or seen a plot of the DR's link.

I should also add that the %s I mentioned above are for off road use. As you go more road and sporting they get less, say 5-10% static and 20-25% laden.

[QUOTE=acesandeights;22358455]To piggyback a bit. I am considering new footpegs. Are Pivot Pegz http://www.pivotpegz.net/ the cat's meow? I am looking for a more offroad oriented peg and don't know if the Pivot Pegz offer much advantage over something like the ProMoto Billet

FWIW I use Pivots and they suit my dodgy old ankles which are also inside MX style boots for support. Also have lowering plates which put them 1" lower and to the rear and further out by the thickness of the plate. Works for me. And you can buy them cheaper in the US than we can where they are made.

If this makes any difference, one of the reasons I'm looking is for traction, but another is that I broke my ankle many years ago and I can drop the front of my foot, but I have a difficult time picking it up (past a certain point) at the toe area (if that makes sense). I can down shift easy enough, but especially when wearing heavier boots, lifting the front of my foot to upshift is more difficult. The DR shifter is placed just at such a point that it's difficult to get under it and be able to lift it (sounds worse than it is, but it makes for slightly slower up shifting). I'm wondering if an aftermarket peg will offer better performance, but maybe also allow for better shifting. I have an insane amount of arthritis in the joint as well and riding a motorcycle causes extreme joint pain after the ride. I don't know if having a solid peg (less joint movement) or one that pivots (probably allowing the joint to flex/move more overall during the ride) will be better.
I shattered my Right ankle when I was 16, I am now 52, I broke my Tibia and fibula and tore many ligaments and shattered my heal I spent 16 hours in surgery this was old school surgery back in 1978 it took me a year till I could walk with out a cane, No rehab back then. so I now use the Pivot Pegs and love the Movement I have with them my right foot has lost 30% movement. Paul.

Thanks guys, sounds like similar circumstance. I guess that's the way to go then.

No chit, my heart broke when someone cancelled our space program. Getting man to the moon was the greatest achievement in mankind's history.

Yes, a hammer needs 0.001 tolerances. Merica engineers don't do metrics.

No apologies necessary when I'm right.

I'm tired too and spending this week in the Canyonlands, however no motorcycle. It's still damn pritty though. Ok, gotta go to bed, more exploring to do tomorrow.

I wanted to get the bigger rear sprocket so I could in fact run "14/44" so when the heavy duty stuff comes along, become the John Deer DR650 tractor. But yes, I've do use the 14/41 setup and does work quite well.

But I really do like the 15/41 for commuting and the highway work that I do occasionaly, as the DR loves to coast along at 110/120 kph quite effortlessly with this setup.

Anyone reccommend going to a 13/41 setup for the knarly stuff. I've read the chain has to turn tighter and thus may wear quicker.

Anyway, I should have sorted it out right the first time but was a bit tight with the cash at the time.


Thanks for the feedback.
