Tire Wear (is my tire just dumb?)

I think I remember seeing that brass screw.  I'll check into that.  The chrome looks nice, so I'll look into servicing it.  Is that something my dealer can do or should I rely on an independant suspension shop to work on it?  It's got a bit over 30K on it plus I replaced all springs front & rear at about 22K.

I'm assuming more rebound damping would mean turn the screw toward the "H" side?  Also, are adjust typically made in 1/2 turn or 1 full turn increments?  I'm not so good with the boingers ~

Yes, turning toward H is more.

There are all different theories as to adjustment.

You should figure where you are by turning all the way in either direction.

Then try a 1/2 or full turn more towards H.

On my 996 I went all the way to H and worked towards S

Don't forget to count the clicks, it's more precise that way ;)

Some dealers will service them, some wont.  If you service the old one consider a re valve and linear spring for your weight also.  Do price new after market shocks, like Ohlins an Penske since you will be spending a lot dollar wise anyway.

Not sure all the stockers 'click'

The Öhlins does.

They click, but it is barely perceptible.  Base setting is turn all the way to hard (clockwiese), then back off 8 clicks.

Hmmm..

I couldn't feel any clicks on my 996.

I'll check again.

Let me throw this out:

Any other models have better rear shocks that would fit an M750?  I could easily put my spring on a different, new shock of  a bike that's been wadded up for pretty cheap that might not be as worn out as my stock shock.  Anything you folks know of?

Mine's a '99 M750

The stocker on my 695 clicks. But indeed it isn't a real click, more a little dimple you come across.

DP, what's the reasoning behind the more rebound damping for this wear?

Keep in mind...

I'm no expert...

but I listen  and the suspender guys say when the rubber 'piles' up on the trailing edge of a sipe and the leading edge is gone away it needs more rebound.

Too much rebound will show as weird arc in between sipes.

Tire pressure is also critical because the tire is an integral part of the suspension.

Keep in mind I destroyed a track tire because I had too much pressure in it.

How much?...hard telling.

The gurus say Michelins are sensitive to 1/2 pound and I had mine set to recommended pressure...at noon.

The temp rose a bit during the afternoon and I was instructing so I didn't have the opportunity to adjust it as the day went on.

That's why suspension tuning can be viewed as black magic.   ;)

sachs shock adjusters click.  showa superbikes ones don't.  i forget about the ss ones.  888 frame based monsters all use the same shock, except the 900 special which had showa or ohlins.  888 shocks go straight in.  i haven't investigated whether the later ones fit or not, but i'd think the damping rates would probably be wrong given the different style of linkage.

i've seen tyre wear like that based on riding styles - the difference between high corner speed on a trailing throttle versus driving thru corners under power sort of thing.  one wears the leading edge, the other the trailing.

Wow, lots of great advice here. Amazing what a simple question about tire wear will garner. I just got a new Ohlins rear for my monster, and will a lot of fun playing with that come spring. It's too cold here now to do any real suspension setup. The road surface is always cold enough to make traction marginal anyways.

Anyways, just my .02: I switched over to Michelin Pilots a few years ago, and I know some people complain about them, and their lifecycle is shorter than some, but since then I haven't had any funny wear patterns, other than wearing more in the center from commuting too much.
