Amazing! He’s a great coach, straight forward and honest. Even though my time with him was short, not one second of the whole hour was wasted. He gauges where you are skill wise and adjusts as needed. Got my list to work on. The videos are great!!! He is truly dedicated to helping riders in this industry.

Thanks for showing me the process of how to learn; having a ‘map’ of how to approach it. I understand it is a process and a dynamic one over time and changing conditions but now feel I have a better understanding of what/how and why each setting should be approached. I like starting with one thing and changing it 25% and then another +25%, making notes and arriving at too much one way or the other and then working back and forth in smaller increments to find the right setting. As my understanding grows and the fear of unknown goes away with experience I am now confident I will soon have a setup that both works and gets the bike geometry with me on it to work in balance. Today’s ride after two days worth of stop/settings change/start/stop was fantastic, best the bike has ever felt.

Dave set up my bike the improvement is unbelievable, I’d recommend anyone who rides get it set up by dave.

Good afternoon,

I really just wanted to say thank you for sharing your knowledge with the community and I wanted to share my experience over the weekend at Barber Motorsports Park with a rear tire issue I was having. Your videos and wealth of knowledge helped me troubleshoot and solve a tearing issue...not before needing to buy a new tire (that was a me problem), but hey, at least it was fixed for the new tire.

It was a lesson in 2 things, you can't always trust the manufacturers recommendations
and dual compounds sometimes make it difficult to determine the type of tearing that's occurring.

Bike: KTM 890 Duke R
Tires: Michelin Power Cup 2 180/55
Group: Advanced
Track: Barber Motorsports Park
Weather: Mostly sunny, mid-70's

Running warmers Michelin recommends 24-25psi (24.65 to be precise). By the second session I was running into what I was identifying as a cold tear.

I dropped pressure 3psi for the following session and took it easy, and as implied it didn't fix anything.

What I think I've determined is that hot tear on a dual compound tire can look a lot like cold tear (relatively narrow patch with deep tears that overlap with virgin rubber underneath) Note the red section below highlighting proper wear on the harder section (sandy beach) of compound which indicates it’s operating within the correct temp range. If it had been a true cold tear due to over inflation, the harder section would’ve likely shown no wear at all (I think), and the softer section still showing something similar (perhaps narrower and deeper).

So I swung the other way with pressure, 26 (waste of time), then 28 (Some improvement), and ultimately landed on 30 to finally clean up the tear. Unfortunately by this point I had very little rubber left on the right side of the tire. It was done.

After finishing off that tire, I switched to a 190/55 (they were out of 180s). Inflated to, what I now knew to be safe, 30psi off the warmer. Now with no tearing, and I probably could have dropped a pound or 2 without issues, but I wasn’t having grip issues so I left it alone.

(No, I didn't compare tire diameter compared to the 180 and/or adjust the front end accordingly - please forgive me for my sins)

Anyways, if you made it this far, thanks again. I was just really excited to be able to apply the knowledge I've gained from your site, and thought you might find it helpful to see a real world example of tearing with the Cup 2s.

Hi Dave,

I would like to share with you that we were at the track on the last Friday and the feeling was amazing!!!!
I glad to share with you my tires

Chris Dick, Tennessee USA (Remote Tune)

Hi Dave.

I’ve plugged in the new settings you recommend. I have to say the my pace has improved dramatically. I went from having chicken strips to draggin knee on left hand turns.

This is all being rode on the dragon/deals gap. I’m including some pics. I just want to say thanks a lot for the help you’ve sent me.

Help us serve you better and take our 30 second survey!
