Suspension Examination:

I must be getting lucky, the trail tech on my '11 was perfect, and touch wood the one on the '14 is behaving as well. The '13 unit is completely different though isn't it? The one fitted to the bike I test rode wasn't working properly either.

The one on my 2010 lasted a long time before it went loopy. The one on my 2013 I am almost certain is over volting. The way its wired it receives unregulated voltage from the stator. Why?? Who knows. I need to splice it into a 12V circuit.

Can't remember how that affects things though? Jake help a brother out?

Haven't measured it but I've got about 4mm play roughly

Went and rode the test track again today with the new suspension settings.

The first few laps were spent trying to dial in the rear shock, in the end surprisingly I ended up using almost the same clicker settings as what I did with the 6.0, although I'm further in with the LSC, running about 4-5 clicks out on LSC now, seems to offer the best balance of keeping it up in the stroke at the same time as allowing some squat to grip when needed. Rebond is the same as what I used with the 6.0, it's a very fine line at the moment between letting it rebound quick enough not to skip over the acceleration bumps on the track to then not pushing on off camber and slippery rocks. No doubt when I next ride a rock garden I'll wind the rebound in a few clicks...

Now the forks, my goal today was to dial in the clickers to where I was happiest with them, then play with the PFP to get a feel for it and see if I could use it to keep the forks up in the stroke whilst being able to wind off the comp clicker.

The rain storms interrupted my testing so I didn't get a chance to do much apart from get the clickers close. The new rebound stack worked well, the clickers are now at 10-11 out (they were at 1), and while I could add a click or two they are close.

The comp clicker is still pretty far in, about 4-5 now, any further in and it stays too high in the stroke and starts deflecting on trail trash. But they are pretty good where they are.

What is much improved is the forks blowing through the stroke and bottoming out, it still happens on the sections where it was doing it in the video that started this thread, but not as often and not as bad. Whether it was the extra shim or increasing the outer oil level to 350mm I don't know, but its better.

No video today as I was on my own, no camera man to film me

10cc of fluid is noticable. Adding 50+cc will make a big difference to bottoming resistance. Good feedback re the rebound!

Jake, I just now watched the video and wish so bad that I had slo-mo of mine. What is happening to the rear on the piece at about 2:38? That is how I would have described my suspension on log hits. Hard lick and see it took his feet off the pegs as well

[n_green]

Yep it's nice now. It ramps up right where I wanted it to but doesn't get stiff or jar through the bars. I may still add a few clicks of rebound, didn't really need it as it wasn't climbing ruts if I was on my game but I like slower rebound up front, feels more settled to me. If I do it will only be a click or two.

What are your thoughts on pfp? Theoretical could you wind it in a few turns to firm up initial travel and hold t up in the stroke and would this allow less comp clickers??
Hmm more testing to go yet...

[Jakobi]

By increasing preload on ICS you are increasing the force required to set the IFP in motion. This is felt in the intial movement of the stroke. One the preload is overcome the spring rate is in effect. Same theory as a shock spring really. The purpose of the pressure spring is to reduce cavitation, the same way that the reservoir works on a shock.

The comp clicker is a bleed/bypass circuit which is active all the time, however based on its size it can only flow at a certain rate before its overhemed and the comp stack has to contribute/flex more.

So really, both effect low shaft speeds speed/smaller forces on the shock. The PFP is probably just a bit more position sensitive in that once the fork is half compressed the shaft displacement has already put a load of preload onto the spring regardless of where you have set the PFP.

Rode my bike for a proper ride yesterday (didn't get to ride down vicco) at cessnock. Super happy with the terry hay shock, totally settled the bike down , makes the front feel better too. Lots of grip, we'll needed at a vey wet cessnock yesterday. Combined with new jetting it was the end of fiddling for me I think.

I spent two days riding at Dalmeny NSW in some prime terrain. Everything from super slow techy rocky climbs, off camber moss covered root infested trails, rocky creek beds, flowing 2nd/3rd gear bermed up single, twin trail with drainage jumps and 4inch to foot thick logs were encountered. My suspension was freaking unreal. It ate everything up. Sensational grip and plushness all weekend.

Still get a bit of a kick from the shock when going over bigger drainage humps but careful body position and throttle blip prevents this.

Not sure on clicker position, the shock rebound is roughly halfway out so that's good, LSC is roughly 5-7 out of 25.
Fork comp is roughly 5-7 out same as rebound so while I could hunt for perfection and shuffle shims to allow the clickers to settle at the halfway mark I don't think I'll bother.
