Enduro Suspension Re-Valves etc

I am posting this here rather than in the suspenion forum hoping to get more response specific to enduro use.

I am considering having my forks re-valved, possibly the shock as well (certainly the fork) on my 97 KTM 300Exc. I see lots of positive on MX-Tech's work here, but am considering more local options with a Race Tech dealer that is just a couple miles away, and happens to be a friend of mine. Also - Enduro Engineering is here in Michigan, and Lansing Cycle does re-valve work too... and I am frequently in their area as well.

So - I understand there seems to be differing "philosophies" on how to set up suspension based on the searchs I have done here. But are they still minor differences, and a decent re-valve by about anyone better than stock?

What is it that say Race Tech, or EE would do that would really differ from MX-Tech? How do they approach things differently?

Perhaps the conclusion might be that MX-Tech is better than Race tech, but would the Race Tech or EE still be notably better than stock?

Any specific experience with these (Race Tech, MX Tech, EE, Lansing Cycle) that someone can comment on?

I bought my bike used, and as far as I know, the suspension has never been re-built or re-valved - so is likely very worn and in need of attention (actually what prompted all this was when my fork seals started drooling recently - if I was gonna have them done, why not go all the way!)

I do think a factor might be it is good to use the local guy when you can, he has helped me out quite a few times and is good to work with... BUT - if Race Tech's specs are gonna be worse off than what I have now... thats a different story.

TIA

Can't say anything bad about the companies you listed because I have never tried them.

I have used WER as has my stepson with excellant results.

Hope this helps.

I have used EE in the past for suspension work and alot of other products for my KTM I have had good luck with then. Alan is a wealth of info about suspension proplems.good luck.

A bud had is '00 400EXC done by EE a few months ago. Much improved, and their price is pretty darned good to boot.

Not sure if Factory Connection does the 'zokes or not. They do good work and are running a special right now.

Since your bike is going into its 6th season, you might consider sending the shock too...

As far as local Race Tech, unless you have lots of people saying he's good then I'd be cautious. Having the Race Tech blessing is like having a bellybutton from what I've seen. He better be good, independent of being "certified" by them.

My buddy and I used Race Tech gold valves on several Kawasakis. Through his trial and error our conclusion was that the valving recommended by RT for woods riding was far from optimum. Better results were obtained by going with much less high speed compression damping than the RT charts showed and increasing the low speed compression damping slightly from the chart, and this approach worked quite well.

My current ride is suspended by Factory Connection and it is awesome in the woods. My preference is for plush on the rocks and roots (light on the high speed compression damping) but can still handle bigger hits with fairly stiff springs and good low speed damping.

Mike,

I have used two companies in Michigan and I was very happy with both. Alan (EE and Lansing Cycle) did work on my shock. I bought my bike from a guy who works at Lowe's Racing. He did the work on my weeping forks.
I would recommend either one.

Thanks all for the replies. Keep em coming - the more i learn of the various options the better.

Regarding the local guy - he really wont have much to offer of his own experience with woods valving - he does a great job it seems with MX/SX valving based on his son's 125 sucess. My guess is at best he can do a good job of exactly what Race Tech specifies, and could likely modify from there if I had some specific recommendations. Tough call still - I hate to not do business with a local shop, not to mention one operated by someone who has gone to bat for me a number of times... but gotta get the thing done right...

So are you looking for the perfect enduro suspension setting, or are you willing to do some trial and error? If the local guy was willing to modify your suspension and then go back in as required to get the valving to your liking, I would go for it. If the local wants to do your suspension and not have any responsibility once the work is done, he is no real advantage over someone not local who may get it right the first time.

'Zokes are their own animal. Those Magnums from that era have a reputation for being hard to work with.

I'd want to make sure whomever worked on them had experience with them if it were me.

My experience with the '97 ecx suspension was good. The stock settings on the Marzocchi 50m RSU and the Ohlins were quite good from the factory for a variety of uses. All suspension units need to be serviced on a regular basis, loss of oil or nitrogen pressure have a profound effect on performance. IMHO, have your local suspension person simply rebuild the forks and shock to stock spec's, and go from there. If you don't have fork boots on those 'zokes, put them on, it really helps seal life. I see no need to revalve the rear shock. If you feel a need to fine tune the forks, experiment with different oil viscosities and oil levels.

I think my local RT dealer will be willing to do a reasonable amount of messing around with my forks - though i had hoped to have this done this winter - not much of time to test them out.

Tm-Enduro - you are about the first person i have heard comment positively about the zokes (seems most every one likes the Ohlins on the rear though). When I think about it though - the complaint with the zokes is the seals - dont really recall tons of complaints with valving. (or is there?).

You may have the best idea yet - rebuild as stock - spend less $ while at it - I am now more leaning towards having EE do it (be it the basic rebuild or the re-valve) - local is more MX oriented, EE is absoultely enduro oriented, and should definetly know what works here in Michigan.

Would appreciate any further comments on the stock valving of the 'zokes - setting aside the routine re-build need - is TM Enduro right here... forks not bad as is so dont re-valve? what do you think?

I'm going to also recommend that you just get your suspension serviced and see how you like it. I purchased my xr400 (used) this summer, and after racing it, and bottoming over EVERYTHING, I decided that I was going to have to get the bike revalved if I was going to ride it anymore. The guy at the shop (BBR) actually recommended that I start with a service, since I didn't know how long it'd been since the last service. Turned out that the oil in both the shock and forks were VERY dirty, and hardly allowing any dampening at all. And one of the gold valves in the forks had come loose, so all the dampening was being done on 1 fork leg! Just having the new, clean oil in there made a world of a difference. I'd give it a shot, it's a much cheaper option.
