MX Tech AER leaf spring mid valve

Even a soft clamp can damage the rod ,if you use the base bolt you cannot damage the rod

So what's the recommendation then? I was thinking I could even use a piece of very hard wood to make a rod holder if needed.

you only need to remove the m6 nut that holds the piston on, just use the cap like Mog suggested.

Thanks, would you still advise disassembling the whole fork, or can I just remove from the bike and lower the outer chamber tube?

[bowser]

you have no choice but to strip the whole fork. Watch some youtube videos prior so you have a better idea of what to do 

[bikedude987]

only need a rod clamp if you're taking the mid stem off the rod...unscrewing the shim clamp nut you can use the wrench flats on the mid valve stem to hold...don't even have to touch the rod.

So I installed the MX-Tech Mid valve today, and have one question. It seems now even after proper bleeding there is a mechanical sound as soon as it goes to rebound, this happens everywhere in the stroke. I tried bleeding it twice, it can't be this. Is this due to the float in the valve or possibly the check valve?

 

Also I found this weird rubber cap looking thing on my bench, could be from a different project but thought I'd double check to make sure I didn't forget it somewhere!

yes that is normal, just the RSV closing.

 

No idea on that cap thing, not from AER forks

The rubber cap is for the rebound clicker.

I think you are thinking of the cap on the bottom of the fork, this isn't that. That one is like 3/4" diameter.

 

I'll call MX-Tech but sounds like this clicking noise on the rebound is ok. Thanks Bowser.

[Rider Eh]

MX-Tech says everything is normal. Thanks guys, look forward to testing this this week. Looks like I may need some shims for the base valve yet to match their settings.

[Rider Eh]

The clunk noise sounds like a loose steering stem, what's weird is guys on KTM talk and a buddy say there's don't make any noise. Can anyone else confirm? I'm a bit nervous as I'm going on a week long riding trip.

[Rider Eh]

Rode yesterday and the new valving is awesome, now I feel like I should do something with the shock. No concerns with the noise either, buddy I rode with is a decent amateur tuner and says his does it as well.

So to add my experience.  Bought a 2020 300 xc after racing a yz250x for the last 2 years. I was surprised how harsh these forks were. I ride primarily single track and the deflection on rocks and roots was pretty bad. I did the mx tech A48r kit cap and leaf spring mid valve with the enduro valving. The results are really good they feel very similar to the kyb spring fork. Nice and plush no more deflection

So im installing the mx tech mid valve leaf spring and its my first time messing with shims and stuff so i need some help or some re assurance my dumbass did this right

Im going to run the HS setting  the only difference between the enduro and HS is .05 on some sizes but that didnt come in the kit so not sure what to do.

This is my compression does it look right sleeve first then 10.1,24.1,10.1 and 10.2 then goes the leaf spring correct? 

This is the rebound there 2 stroke/ offroad setting the only shim im missing is the last 10.3 do i not run ir or just double stack the 12.1?

mid valve on

That top nut bottoms out do i run that big top spacer? thats the factory piece 

Bike is a 2019 TX300

[TCMB371]

Kinda jumping on this late. Is the MX-Tech leaf spring just a preloaded face shim via a cupped piston? Couldn't the same/similar damping curve be achieved by using a ring shim setup with a similar "cup" depth and using the stock midvalve piston?

Also, this would produce a vastly digressive damping curve. Has anyone put their MXTech Leaf Spring Midvalve on a dyno or ran the numbers in ReStackor?

[m78val]

I thought they gave a range of to be In 45.25mm down from top of check valve to nut on rod, you can add spacers directly under check valve

Im at 50mm no matter what that top check valve/nut bottoms out

 

So rode it around a few more times i guess it feels ok, i'll find out race day unless mc-tech replies and says something wrong

[m78val]

Pretty sure you want to be at what they suggest, or you have to change spacer out, if need be you can tell me what thickness it is, I can make you one a little shorter and get it to you 

[IronUA]

But where does the spacer go? It came with 3 different size spacers but the top check valve/nut bottoms out i cant get it under 50mm no matter what. unless im measuring it wrong
