Nicest 950/990 saddle I've seen in quite some time

Wattner is a really cool guy, couldn't have had a better buyer.

I found a good resource on chain wear after I asked. I guess the issue is that mathematically it puts the same link in the same tooth every few turns, whereas even/odd spreads out the contact.

Issue? Theoretically it would wear some teeth/links worse than others and shorten the life.

Reality seems to suggest unless you're running a chain oiler and getting 50k out of your chains you won't see the difference.

Anyway, I like to be a rolling experiment....it's science and shit!

Look at an even number front sprocket, the inner plates wear the same teeth and every other tooth is missed by the outer plates. I think if you had odd number teeth on both sprockets, then each tooth would alternate between inner and outer plates.

Seems to me for that particular roller to hit that same tooth on a regular basis, the number of rollers on the chain would have to be divisible by the number of teeth on the sprocket and the result be a whole number, otherwise, that tooth would hit a different roller next time up to bat.

I think that makes sense or I'm comparing your chain to the contact patch of the jeans posted above...

Wow, I guess I have put on some weight since that photo was taken. Sorry bout the plummers crack.

Yeah, something like that I can't stop thinking about asses now....so math is like, unpossible.

Maybe this will take your mind off asses, Advr skinny400...

Geared...




Missing some gear...

Anyone know?

Hmmm. Not sure if it's true or not, but it's something to think about.
The right gearing is very important & new sprocket/chain sets ain't cheap.

Swingset, have you seen this?....

I'm mulling over gearing choices for my old XL250 right now.
From the XL forum....
[QUOTE=jitterymonkey;]

Hate to keep beating a dead horse, but I'm gonna

The wheels are done & the new Pirelli MT43s are mounted for my '72 XL250.
But, I can't decide which sprockets to use.
Mainly be commuting on paved back roads (35-45 mph) during the week &
dirt roads/trails on the weekend.

I have these new sprockets to try...14/15 front & 42/48 rear

15x42 (2.80)
14x42 (3.00)
15x48 (3.20)-Stock gearing for my '72 XL250 (45-50 mph max)
14x48 (3.43)

Of course the 42 rear would be great for my on road commute.
But will it work in the dirt & Ohio/WV mud?
& (of course) the 48 tooth would be better off road.
But will it put to much strain on the motor trying to keep up with traffic?
(even if it's just back roads)

Anyway, writing it all out kinda helps (thinking about trying 14x42 first.
Thanks for reading & any advise.[QUOTE]

You all are lucky, I've tested my KLR with the following sprockets
15/43
14/43
15/45
14/45
13/45
All I found was with a 13/45 I could pull a wheelie with only half throttle. Chain ware was not effected to any obvious amount. Currently I think the 15/45 setup in on there.

Interesting. Found this link:

http://www.gearingcommander.com/

According to this, with a 16/42 combo, and 112 links in a chain, my front sprocket has the same link in the same tooth every turn, the rear every 3 turns and both sprockets at the same position every 3 turns....that's opposed to the stock gearing being 17/41 which means the front goes 17 rotations, the rear 41 rotations, and the combination only lines up every 697 rotations.

That's quite a difference. I'm not sure how it affects wear, but that's not a marginal difference in mating surface time over the course of thousands of miles. The math works out to every mile traveled, my current gearing would have the same link in the same tooth 200x more than stock gearing. Apply that across 20k miles? I could see that affecting things.

Dunno, I'm not a structural engineer so I guess there's more at work than just the math on same/same contact, with regards to faster wear...would probably depend on tiny differences between one link/tooth and the ones next to it and the same goes for the links.

Geesh, my head hurts again.

Just ride it, Craig.
