Yfz shocks

[Speed37]

I seen some members on here with yfz shocks. What did you guys do to make them fit??? Cause my neighbor has a pair and I tried it on and the bottom mount is good, just the top mount on the shock is too wide. So is it a certain year shock or do u modify it?

Take a bandsaw, cut off wheel, etc and cut off about 1/8 from each side of the top mount.

They work fine after that, do make the quad sit a bit lower tho.

Did you do this mod cjm?

there is a video on youtube of what you need to do to make it fit. Seems very easy if you have the tools for it.

he used 450r shocks. use the search bar and theres numerous threads on it. :muscle:

No finster I'm trying to use yfz shocks. Not trx shocks

[CJM]

If you search you will find it.

But like I said, you need to cut the shock eye area of the shock down to fit. 1/8" each side if I recall and they fit.

The spring rates actually rather good and you get kinda dual rate spring setup.

i meant it like no CJM didnt but you can search for the yfz shock install.

i have a yfz450 that i'm putting float evols on and i was wondering if the stock yfz's are better than the stock honda 450r's?

i have the 450r's on my 400 right now and they jsut seem hard and stiff. Is it just me? i have adjusted them but for some reason the yfz's seem to work better.

the 450's are a definetly an improvement on the stock 400ex but the stock 450r shock is stiff!

Spent 10 mins grinding the upper shock eye holes skinnier. I loved how they made the quad handle and sit. But after putting +3 arms on the shocks valving was way to soft.

read this from nick@jet

Sorry , but there are some problems with stock shocks in stock form, that is why we do what we do with them.
Fronts are generally too stiff initially, and too soft on G-out, quad too high in the air, rear rebound too fast even if you screw all the way in, motion ratio of the rear linkage isn't great and compression adjusters don't do much when you dyno them. I am lucky to feel a noticeable difference between full hard and full soft. Rebound adjustment is a different story. All of these are addressed except for compression adjuster when we do our JET mods.

Spring preload adjusters adjust ride height - not sure how much you weigh but for woods and trail riding stock shocks, I would back off the preload adjusters until there is little or no preload on the springs (you can feel when quad is off the ground and just pulling down on the spring itself to feel the tension on it). Rear - the same unless you weigh above 225. This lowers the quad and gives a softer ride.

S = soft / H = hard (i'm sure you knew that)

Front and rear shocks, back off compression all the way until you get them modified.

Front rebound - slow enough so when your pushing down on the front with you hands it doesn't spring right back at you.

Rear rebound - screw all the way Hard easily (don't cram on this or you will damage it) then back off toward soft 1/2 to 3/4 turn. You never want to run the rebound all the way hard since this closes off the bypass needle inside ...which affects low speed compression as well! and we need the compression free so it can absorb all those little hits, rocks, cross ruts and roots and still maintain some plushness.

That is about all you can do with stock since they need some work, but the shocks themselves are a good platform with the steel tube and are fairly easy on oil for stock shocks.

KEEP THOSE shock bearings lubed!! You need help further, you can email me. Now I got to get back and build some shocks...
