i have read in threads that to measure preload u have to take stock springs out put in new ones and screwthe fork cap on and measure the distance between top of spring and bottom of fork cap.is it the same to just measure from top of spring to top of tube then subtract the length of the cap that goes intothe tube??? thanx by the way i have an 01kawasaki kdx200 and the springs r .42 frp
yep got them three days ago it says to use stock every thing but not oil. if i dont change the fork oil what will happen will i gain som of the stiffness back if i used more preload. i want to jump what would be good for that in means of fork and shock adjustment i weigh 190 lb if that helps
The oem oil is generally considered to be junk. Besides, seal life and general fork action will benefit from an oil change. MX-tech recommends mobil1 ATF for home use.
Adding preload is not much of a way to add stiffness. You would be better served using a thicker fork oil for that (buy some belray oil). Fill to a relatively high oil level, say 90mm or so.
The best option for making the kdx a jumper is to excise the 'd' in the middle. Which is to say, buy a bike in the first place that's more of a jumper.
