Rain is good! Hope you get to ride on that good dirt! I also don’t blame you one bit for being on fence duty. Wrangling cows all over the place is not fun. I grew up in Fort Sumner and it’s one of the things I don’t miss too much about living in the ... more »

Suzuki, if your listening. Produce a new 350 with Kyb suspension. You won’t regret it.

I vote long bed gasser. Close the tailgate and work on it when you need too.

That’s out of my league at the moment.! I have pretty much blown my moto budget for the year already unfortunately. I’m hoping by the middle of next year can pick up a leftover or a clean used one.

I've done a lot of work on suspension and frankly it's not difficult if you know some of the design stuff and what changes do what to the feel. I did have the opportunity to learned a few things from Jim Lindemann back in the 1980's and others. Jim did the new shock valving spec's for Bob Fox at Fox Racing before leaving. I had Jim do some work for me long ago… And others. Infact Jim and I were going over the valving put in a CR125 by Jake Thompson many a moon ago. Jake was at Honda - probably before Mike Batista. A buddy of mine also ran the power sports division @ Fox Shocks for 20+ years and he taught me a few things. If you know what shims do what in the stack it helps a lot. Then you have to know what it is YOU like. And from there what buttons you have to push to get to what you like. There isn't a set "formula". There can be a lot of experimentation. And infact I started doing my own stuff when I kept having to take it back to guys I paid to do it and it didn’t work…..If there was a formula the factories would setup a bike and it would just work for everyone in a given weight range. But there is no such formula. IMO it's all about setting up the bike for the specific rider and knowing what button to push when you get certain feedback. Should you change the low speed compression? High Speed? Pivot shim? Spring rate? ICS spring? Mid valve float? Piston? What about linkage?
Infact, relative to this thread, I struggled getting my KTM 350 XCF to work how I wanted. I went super light on the low speed compression valving to get the square edge compliance that I set my bikes up for…only to have bottoming problems. I started to put more HS compression back into the shock and was starting to play around with a bigger pivot shim on the shock when I read a description from Luxon discussing the EXACT issue I was having. So I realized it wasn’t just me…
I also had these two kids move into a house down the street from me who had a garage full of dirt bikes and several Alta’s. I was thinking… hmm.. you don’t see a lot of Alta’s around but their garage was full of them. So I stopped one day and started talking to them. Turns out these two were the chassis engineers at Alta. So I brought up the KTM linkage issue and he looked at me and said “you know who Dave Arnold is”. He explained how Alta hired him to work with him on the chassis. From there we got into a detailed discussion on the linkage design KTM is using and why they are using it…

So, buy the knuckle. )

I always do them as a pair so they are tuned together. The shock is a huge improvement from stock. The feel is kinda firm but extremely plush. It has no harsh spot anywhere in the stroke. Square edges are very common here in New Mexico and I have to ... more »

Yes. Mine are very good. I actually prefer them to the cone valves I had on my last bike. I’m on a 350 as well. Was worth every penny.

Thanks! I tend to gravitate towards the stock look myself. I honestly think some OEM rockstar edition plastic along with a white frame and gold wheels would be super cool though!.
