First, I have watched the Dave Moss videos online but I can't find the one which addresses this question.

I am very close with my suspension settings, just looking for some minor refinements. I ride a 600 F4i on Q2s and have found about 30psi, front and rear does well for me. I have my springs right now and the ride height is working to make the bike suit my style. I get good graining on almost the whole tire after a spirited session.

I am still refining my rebound/compression settings though and I need to know what a slightly lower (more worn) front edge of the tread sipes indicates? Is it too much or too little rebound dampnening? This is not a big radical difference, but the rear of the tread figures have a tiny raised ridge and the leading edge is slightly rounded down into the tread...

I am guessing I'm really close and just a quarter turn or two away from right on... at this stage I'd like to go the right way because I have a track day coming soon and I'm about to mount another fresh rear, then hit the track...it'd be nice to have it perfect....enough....

Thanks, if anyone can answer....

Disregard the dirt. Pics taken following a 200mi. twisty road ride to Fossil, Oregon at a 'spirited pace' but not race pace.
First two are the rear tread...


another rear


the one below is my front tire, right side, taken looking straight down. It is showing more wear on the rear edges of the sipes..

Looks normal to me. You're on the gas while turning, which is good. The feathering is from torque of the wheel twisting the tire as it grips. The lower pressure twists the tire more. Increase your pressure to help the wear, but not so much that you lose traction.

I'd leave the pressure where it's at and be proud of your technique. Mine look the same....

 

Thanks, the settings seem real close but

...still, someone....Which way does Dave Moss suggest the settings go? I recall but can't find, in all the hours of online videos he has...(with lots of ads and lock-ups on my connection) the one in which he says..."When the back of the grove is higher than the front, it means you have......" I am close enough that I am now changing by quarter turns on my settings...I'll have a hard time quantifying any results by actual observation, I think, so I thought I'd just ask first...

Most track day providers will have a suspension guy or gal there.I would pay the $20.00 or $40.00 that they charge to get it perfect.Dave Moss does all my suspension work,best $20.00 I have spent.

 

Pressure related I'd think. Those tires shred alot for street riding, reminds me of BT016's.

 

I believe this is the video you're looking for.
