Fork preload adjusters

2008 RK with a Showa 41mm fork

I am redoing my suspension and want to use pre-load adjustable fork caps, simply to make set up a one time easy adjustment rather than play with spacers. This will also allow me to increase preload when the bike load changes

This is a conventional design Shown fork so I do not see how it would be any different from an aftermarket cap for a Jap bike.

My bike is halfway around the world right now and it seems likely that Showa used the same thread on all their 41mm fork tubes. - Does anyone have the thread size and pitch
I am hoping it is M37 x 1mm

Those won't work on your 08 RK. Your Top Tree doesn't clamp around the Tube.

Serves me right for not looking at the manual first!
If it was this easy everyone would do it.........................

Does anyone made an adjuster that will work?

Several people use these for improving the front end suspension. They are adjustable at the time of installation, but cannot be changed on the fly...

I have cartridge emulators and looking to adjust the preload. In any case the fork cap is unaccesable so a bad idea and stupid question to ask without looking at the manual first
