any valve mods for a ktm 08 530 forks

Recommended Posts

My 08 530 exc which i resprung for my weight doesnt seem to have the same plushness as my 09 300 exc again sprung for my weight, did ktm make internal changes between years and is there a general mod that people are doing with their 08 models... and just to clear both bikes are oc type

thanks

they altered the tubes on the cc forks to make them flex more in 09, but i dont know on the oc forks, ktm valving will be very different, the valving will be very different IMO.

wp send out pdf files of stacks to tuners, not to the general public. The suspension world is very secretitive.

The 09 forks changed cartridge diameter so the are much nicer the 08 which really suck.

Here's some stuff I did the might help:

lower oil level down to the 140-130 range

change oil to 2.5wt

revalve to remove 8 24.1 shims from base valve.

I will also soon be swapping out fork seals to SKF and Kyb bushing to help remove the excessive stiction.

its not that expensive to upgrade to the 09 internals, bluerider may still have the part # no list I sent him, if not i'll dig it up in the morning

That's about $375 US worth of parts for a set of forks. You might be better off just sending them out to get revalved by a pro shop.

the upgrade to the smaller cart diam nets better results than a "pro tuner" can coax from the 08 stuff, just MHO

hey bush , looking at the setting list would you think that just to change the comp stack and leave the 08 rebound stack i would get good results
