Nice job guys! Thanks for doing this

Do I smell a TWF-Spec V3 in the future?

TWF

Yes Steve, will try couple things. Than do dyno run and see what we get and go from there. I don't have dyno but have friend with one.
It would be nice to know what difference is between two so if you don't mind I would love to open it, if you get them.

So if I got a set and got them sent to you how long do you think it would be until I got them back?

TWF

Few days.

Steve, if you send in your ClubSports we'll finally be able to see if they are really valved stiffer than the V3. We've heard yes and no from KW USA techs so we're not sure.

yeah....I'd just hate to find out they aren't any different and I paid all that extra for nothing (except for the solid top hats) but if that's the case I could get my own tops and springs for less than the difference. I like just blindly believing they are stiffer

Here's an update on what's going on with our KW V3 revalve project. TWF revalved the high speed rebound of my left front shock. We had it dyno'd to see where we are. I'm going to send my right front V3 to be dyno'd before it's revalved so we'll have a before and after. Here's the dyno of the revalved shock:




Click on the chart to enlarge it so you can read the legend.


Compression (bump) is the top half of the chart, rebound is the bottom half.


The chart's legend shows B for bump (compression) and low speed setting (sweeps or 1/4 turn), high speed setting (0 since it's not adjustable), R for rebound and the low speed setting (in 1/4 turns NOT clicks), and the high speed setting of 0.

This shock has not been rebuilt because KW USA will not sell us the main wear item--the piston rod seal at the top of the shock. Its valving was altered and it was reassembled with new oil and the nitrogen bladder was inflated to 60psi.

The red line shows compression set at 5 sweeps out from full stiff (1 1/4 turns) and rebound set at 6 (1 1/2 turns out).
The dark blue line shows compression set at 5 sweeps out (1 1/4 turns) and rebound set at full stiff.

It's my best guess that we have gained some adjustment in rebound but we won't know for sure until we get my unaltered shock dyno'd.

so if KW USA won't sell the wear items, can TWF source replacement parts?

TWF

I did not try to call KW and order seals yet, Rob did not need one. I will try and go from there. If they don't want to sell there are other options.
Other seal in there is common and I had that in stock and did use new one on assembly.
