YES SIR
can I wait till it stops pouring rain out?

Finally got a day to test the new spring. I believe I Finally got it set good to start. I did find out that the tires I have on are junk in the sloppy mud after 4days of rain here in western Pennsylvania. Hopefully the farmer doesn't get pissed from me sliding across the one field just once. Lol

PS. Thanks for the insight folks
Was servicing this fork the other day
It's a good reminder: no matter what fancy coatings you have in the fork or shock, if you neglect the service for too long, you will ruin it.
Keep the oil fresh and change those piston bands and bushings in time before they wear out.

I have lowered all of my bikes in the last 8 years. Lowering links change the leverage on the shock, so I always go with internal spacers. It is a good idea to lower the front a similar amount, so you don’t change geometry too much.
Hi everybody, I'm a fork hoarder.
But as we all know, one can never have too many CC forks. I already own a couple but when I came about this I had to buy it.
The fork is from a 2015 SX-F 450 so it's the last year of the WP closed cartridge (with all the updates) and lugs for the small axle.
The fork is practically unused and it has never been opened. With a slight shim shuffle it'll be perfect for enduro for many years to come.

Good find 👍
Found quite a surprise when I took the CC fork apart.
The mid-valve compression face shims were not properly centred on the post before assembly so they were all mangled.
Maybe this fork was assembled on Monday morning right after the Oktoberfest

KTM still has serious quality control issues. About like ChevroletFound quite a surprise when I took the CC fork apart.

Beware racetech's suspension recommendations are typically .......questionable. Specially when it comes to springs.

They tend to go overboard, just by their configuration tool, leans WAY to the side of too heavy.

Suspensions are like chess though, easy concept BITCH to master.
At a fundamental level its get the sag right, and if you can't get the sag right ...re-spring.
Once you have the sag right its a matter of tuning how fast or slow the stuff moves. This is compounded by triple circuit (high/low speed compression) and things like air gap which are style/art type decisions.
You can actually math it out with relation to the spring rate, its literally cm/kg or inch/pound (easier in metric).

That’s an excellent book. Makes my brain hurt (in a good way) every time I read it.

Yeah, so at that point. Time to get new springs.

Compare Spring Manufacturer Recommendations, and be honest about how actually ride the bike with all your gear and supplies for a weight analysis. I see you dont MX, but some air time in CO can be fun gonig across Stony Pass et. al.
When I was shopping to sort out the CRF450L, opinions varied a lot.
- Racetec calculator 6.3
- Cannon Spring tech on the phone 6.8
My first ride (literally) on the new set up was at the start line of the AMA Ozark 200, and what a difference it made, in a good way.
We have a natural tendency to think that stiffer springs are going to give a harsh ride, so we aren't truthful about weight. Yeah, an empty 1 ton truck rides a bit rough, but that's not how bikes work. Probably the most common cause of a harsh riding bike is one that is undersprung and blowing through the valving.
I'm 220-240 lbs depending on gear. Every time I increase spring rates ( every bike for me) the ride becomes so much smoother. Then you can start fine tuning the damping.

going to much heavier springs with proper dampening made CRF Plush. Night and Day difference. I now could use the Full suspension travel.

That's a good one. Does a pretty good job of making complex subject look simple.
Although why "Springs control ride height" and "dampers control suspension speed" needs a whole book is beyond me.
