My YZ250 has 2mm of a friction zone. If it had 5 mm, I think I would make sure the linkage and swing arm pivot are greased well. The shock length can change with a pre-load adjustment? The rider is in a slightly different position, (or ate, took a dump, etc.), for the other measurement. Have you ever read the "Motorcycle suspension bible" by Paul Thede? lol

Why worry about pulling a measurement from the center of the axle? Unless the end of the tape fits snug its going to be hard to get the center everytime. Clip the axle nut seems much more logical, but I'm not the "expert". I hope they rebuild bettter than they set up.

How about free sag? I've been setting my sag up for 35 years and was scratching my head when the expert was calling out numbers? What was he talking about?

I can't believe i have never seen this. Thankyou sir this video will become a weekly watch for me and my son!

Great info thanks RACE TECH

I need a stiffer ride. to much sag in rear suspension. I’m 225 lbs so I don’t know if I need to buy a stiffer spring or just do the math and adjust accordingly. Also need to adjust the front suspension for a an overall more sporty ride. Any help much appreciated. I have a 2022 gas gas Mc 450f with WP suspension.

Go ahead🤙

Great explanation, thank you.

Thanks Paul! Disappointed that you don't make one small enough for a set of XR100 forks!

I am 220 pounds. How do I calculate my SAG number? How would I calculate it for somebody who is 150 pounds?

this guys explains it very well ill be sending my suspension to race tech!

Is this asfalt only or would that completely change these settings?

Ok this still doesnt answer where your sag should be set at 😅

Yes

/sF(x)= p'''(z= bcvR'''itTn) + {sfr : frqs} < labx id mtrx cvIIIr'R''' abv 4/ /cF(y) int = avn cg(xz) sM(R'''cvk)//> P'parch id mtrx(II ljz' + III ljx int= sF(x)) dbl paavlow || kon/

RT'TECH' = MOHYK' - RKN'TN'-- Learned in! That mean: "You will be, damn destroyed!"

And my PHAMZ, and I, "Own KTM!" Cannot claim - any of thee - ABOVE! YZ= frame || HRC motor! They didn't mention - any YZ chas? Not even - them crazy AMA! AMA = "I attacked eu!"

You should at least mention checking the static sag after doing the rider (dynamic) sag. Status is the sag from extended to compressed just by the weight of the bike, no rider. If your manual says the bike is equipped with a rear spring for say a 165 lb rider and that’s not you, then you go adjust your dynamic sag, then your setup may end up too far from acceptable, because you’re too light, or more likely too heavy, say 200lbs.

Paul 86rm 250 article I remembered him modifying thr Suzuki withe highly resistant linkakage he had polished and harden .but I was wondering if thehe knows the kx250 2005 Aoss kyb mid stroke shim positions since mine fell apart with it coming off

I wonder if it would make sense to put a series of smaller additional holes in the damper rod higher up on the rod (rather than two large holes right next to original ones), to progressively increase compression damping (and decrease rebound damping) as the fork gets more and more compressed. Seems like it could provide additional protection against bottoming out while not affecting handling in the middle of the suspension travel.

Can you tell me the setting on these emulators please. Eg: tightening the spring = ? Loosening the Spring = ? Cheers

wow,no wonder why they charge 2k for a pair of forks on the bigger bikes

What about rebound damping? Does drilling the damping rod make rebound quicker? I'm installing heavier fork springs so I also need more rebound damping.

Thanks

I started doing my own suspension and I wonder: how much air is trapped under the seal head with this method? And how can I bleed the last bit of air from the shock?

Put your richard on your bike

This vid would have helped me in my 80's racing days. Especially with mental attitude. I was a different (and slower) guy on race day. I could beat or keep up with my buddies on our practice tracks, but had a real hard time riding to my actual level on race day. But I am happy to say I did win a couple races,---with no confidence. lol

3:55 Good saying. I have another similar. "The day you think you know it all, is the day you have a lot to learn." :)

After much thought after riding again after 18 years off a bike, it seems to me there are 2 was of setting up your bike today. 1) The new way, people ride more forward with handlebars rotated forward, and to compensate for that, they are running more rear end sag (105mm or more), and more static sag (about 35mm). I don't like the way the front end feel in corners with the bars up that high so I went back to our old set up. 2) rotate the bars back down so the ends of the grips are pointing down a bit, (corners so much easier for me), and get the sag set between 95-100mm, with the static sag at about 20-25mm.) I see a lot of amateur kids with go-pros on the modern tall bikes with high bars, who can't corner worth a crap, and pretty much have to have a berm to turn at all. Even in the C class in the 80's, there would be a couple of slow guys, but I have never seen so many slow guys in the corners as I do today. Like everybody.

I have a 99 vmax with progressive spring. I know racetech sells flat rate springs but my progressive springs are practically new. Researching i find mixed results on in the cartridge emulators are compatible with a progressive rate springs. Are they compatible?

Thank you for having these videos online and free to view.

I understand that you guys are the suspension gurus... but what about free sag? This should of been discussed so that other people have an understanding of whether they have the correct spring rate for their weight.

How about the front?

My sag is 55mm. I just ordered Race Tech 5.4kg shock spring. I weigh 155lbs. Am I going in the right direction? Should I get the gold valve also?

Who are you who are so wise in the ways of the science?

I have this on DVD 😁

Go ahead!

I watched this almost every day after school for a long while. Still talk about it to this day.

Could you do one on front spring pre load? KYB.

Glad to see fresh tips here. Love my gold valves and set up. Keep em coming.

He forgot to tell you that in competition first place is the first loser (in life).

Ktm triple clamp Fork pinch bolts 106 inch lbs lower clamp bolts & 150 in lbs for the upper. Honda lowers are 180 in lbs, 192 upper. Yamaha 168 in lbs lower, 204 in lbs/17 ft lbs upper.

Good stuff. 🤙

Good stuff Paul. I just saw this after all these years and it’s still valuable and I’ll bet overlooked..

Some YT techs (lol) are saying to plug the tiny rebound hole at the top of the damper rod. True??? Racetech says nothing about the little hole.

Too the MOON! THANKS PAUL!

Dude,,,,, genius. To make something "simple" to address something so complicated..... and guaranteed. Thank You for sharing.

Hmm, no talk about rebound or the effects of rebound vs improvement to compression with this device

When I replaced the springs in my wife's bikes and was offered this option. I turned it down. Now that I know more about what they do... I will say yes
