Hi, have a 17 TC250. Also have a 18 TC125. The newer 125 fork seems better on small bumps. Which upgrade to the 17s - MXtech mid-valve with shims $140,,,stock Husky 18 midvalve for $66,,or ???
Thanks for feedback.
The Shop
And he told me the best way is to make a Service and Update the Suspension with 2018 Parts.
A New Air Piston and a New Seal Head on the Cartrige.
New Seals on the Seperating Piston for Low Friction
replace two thick O-Rings on the Shock and 2018
Setup.
He told me i will be surprised how good the Suspension will work.
Even more crazy they say air forks are too complex so they add in an extra chamber or 2 that requires yet more setup

for the new mid valve, air piston with better seal less friction, and compression seal kit for less friction14,24,26 ????
It’s a two stroke, set your sag and hold her wide.
For the air side, the stock chamber has a very progressive ramping up of resistance, not a smooth, linear increase like a spring does. The A48R chamber helps make the air side more linear like a spring. Similar goal of either Enzo's remote reservoirs, or the old Yamaha speedo/tach forks.
The stock '17 AER fork's midvalve is a very simple design, and doesn't have any float. This makes for a harsher ride. I believe the '18 changes address this issue. Changing to the '18 midvalve or the MXT midvalve would both help the action of the forks.
That said I think It's over reaching its a performance upgrade. In hindsight I would have probably swapped out the new upgraded oem metal piston.
I've also got the tank, I bought it for practical reasons since it was supposed to come with a Schrader, but it didn't lol.
James Dunn won a emx250 round on revalved stock stuff so that says a lot.
Thanks for inputs

Karl Anderson (KAS Suspension) really does work miracles with these forks.
I think he updated my forks last time and my forks feel amazing and it’s a very comfortable bike to ride thanks to the updates etc.

I maybe on hold with OEM vendor for months.
