oil for TM400 forks

[Marc.com]

Anyone got a hot fork oil set up for the TM400. Is it worth doing the PDS valve thing, I had some Racetech ones in my Harley and it handled worse.

Bullshit a harley couldn't possibly handle worse no matter what you did to it 

As for your TM just get out and ride the thing  hold the gas on and it will handle fine as is  after those hardleys you like it will seem like a factory racer even with flat tyres

I fitted Yamaha forks to my TM......Solved everything.

So let me get that straight if I fit the Harley forks it will work better.

Any thoughts on oil quantity ?

thanks Bill 190cc of Hypoid it is then    Harley Davidson actually does a performance fork oil that flows like Golden Syrup so I might go with that.

You should end up with around a 105mm air gap
