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.

Hi Dave,

The tires are fine as I performed the test you mentioned. After making the adjustments you suggested the bike has completely transformed into a laser! This is exactly what I was looking for.

Your advice was crucial to getting my bike set up correctly and it is now up to me to stay ahead of my skill with Suspension tuning and I will be watching and learning from your videos!!

Thank You!!

Sincerely,

Randall

Hi Dave,

Great to see you again even if you prolly don't remember me since the last time I did a track day was 5 or 6 years ago but you can't imagine how happy I was to see your trailer! As I get older I'm finally appreciating all the things I don't know and I'm a slow learner.

So, Hyper springs... I had a 450 lb/in in there and it turns out it was at 3.9" installed length or 1.1" preload which is 25.5mm vs the 8 you recommended! that tool over 10 full turns on the ring nut- yikes. That's what it took to get 40mm rider sag. The rear total travel is advertised at 150mm and 25% of that is 37.5mm. I'm not sure how important that is but with the current ride height it handles very good and I think I should preserve that?!

I just installed the 500 lb spring and with 8mm spring compression at full drop the rider sag becomes 60mm.
That is 20mm less rear ride height and I think I would want to preserver that to get the same geometry. I can achieve that with adjusting the ride height adjuster or adding more spring preload. I'm not sure that I can get 20mm out of the ride height along but I'll try...

My shock has a ride height adjuster which is a giant heim joint. I measured it previously and it has 14 turns of max engagement so I'm assuming I can go 7 turns out max for safety and keep 7 turns in the shock... do you agree with that?
I was at 3 turns out and now with 7 turns out the rider sag is just over 50mm, so 10 more that before. I'm happy to say that the static sag with no wider is about 15mm right now. So long story short, I have the 500lb spring in, 8mm of static sag and 50mm rider sag, only problem ins I's like 40mm rider sag. I can do one of 5 things-
a) leave it alone
b) lower the front more
c) add rear spring preload
d) reduce the heim engagement another turn or two
or e) get a heavier spring.
I actually used to have a 550 spring but it felt so stiff that I sold it, I wish I had it now to at least try it :)

I may be at the April 15 Fun Track Dayz if I can swing it, looking forward to learning a little more.

Hi Dave,

It was great to meet you on the weekend at Hampton downs raceway.

Watching you working with Dillon Telford & then seeing the difference in the way the bike handled after your advice was awesome It certainly gave our team a lift we needed. Hope to see you again at Manfield!
