TCS / Racetech to the rescue.......
sure would like to know what front springs are on it, and if they are 1.88" mains how they squeezed them on............i've seen a racer at the itp quadcross with pep revalves. it had different front springs. i talked to the guy and i think he said wayne charged him somewhere near a grand for all three.
FINALLY validation of what I've been saying all along.......... the stock setting /set - up is crappola........ raer springs are 8 - 9 KG/mm, 7.5 is whats recommended for 200 lbs.......Wayne at PEP was heavily involved in the development of the quad (as well as many pro riders) and claims KTM over-valved and over-sprung the hell out of the shocks. Seth @ SF actually laughed when I told him my weight (about 150 - I know, I'm light) because the shocks are known to be way, way, way too stiff for anyone under 280lbs:angry: (not a mis-type, 280). I could barely believe it but I guess it's true. I find this to also be very interesting because I do not find the shocks to be that stiff, but I think I am just convincing myself that they are not because the manual says they should accomodate my weight, therefore I should have no reason to complain.
The Pro Racer who won the Pro and Vets OZ MX National in 2007 (A Honda ATV NRG set up with Outlaw LSR Swinger and LSR A Arms wit Ohlins PDS ) He is 250Lbs and loves these WP shocks out of the crate ! :lol: We did another 20 sets to Racers here and PEP got 1st and 3rd Pro and 1st ,2nd and 3rd in Vets here at the 2008 MX Nationals just gone .FINALLY validation of what I've been saying all along.......... the stock setting /set - up is crappola........ raer springs are 8 - 9 KG/mm, 7.5 is whats recommended for 200 lbs.......
My valving guy made mega changes in the valving department. We have changed all the rear springs, and the front is next, I guess PEP machined down the front bodies to get 1.88" springs to fit, no one makes 2"ID springs suitable.........
If I lived in the US i'd have Wayne do the work based on wmat I've spent and still have to do the PEP price is on the money. Either that or bin the useless POS............... and fit up either PEP ZPS / AXIS PRS.

I need to talk with you tomorrow in aus, send me your details. Yeah at 250lbs he probably is getting things to move, it will still benefit from significantly from alterations especially in the low speed valving.
Zero preload, Wayne would like you to beileve that no one else has this, but that isn't correct,
TCS has race series - No preload
AXIS has Plush Ride System (PRS),
Fox has the Evol chamber on the Floats - ride height adjuster
and Elka has a similar setup ? sag control ?,
they just can't call it ZPS / Zero preload as Wayne has a trademark on the name, but no patent on the concept I believe.
All the major shock suppliers have a zero preload type system on offer, even Works offer this in there OEM upgrade spring kits as an option.
I doing a truckload of work on the WP's the details of which will go to KTM NZ, which is linked to KTM Australia and the new KTM race team just announced in Aus.
I agree that the no link system has challenges, but the WP and Ohlins shocks have a secondary internal piston which provides additional progressive damping resistance as the shock compressed past 2/3 travel. Combine this with a well though out proper dual rate spring setup in the rear (the stock SX setup is way off the mark, i'll post why over in the suspension section) and there will be a huge improvement. ZPS ride height adjustability will be the icing on the cake...........
