My bike has travelled 27000klms should the fork oil be changed,what would you reccomend as to what oil,change frequency is not in the service data

SOURCE: oil change frequency

I change once a year, which is more or less 3000 miles for me. I use a Purolator Pure One 14612 filter and Amsoil Motorcycle 20W50. Other people do differently, just search for some oil threads. I can't imagine that changing your oil more frequently than recommended would violate the warranty.

its 120 mm or 4.7 inches from the top of the fork
Some measure the oil quantity and fill the fork up, some fill the fork up and measure the oil level. The most correct method is to measure the level, I guess, but many guys measure in quantity.. both ways work well.

SOURCE: How much fork oil in a 2002 KTM 400 SX

White power allow a 110mm air gap with springs out and fork compressed as a general guide ,adjust from there according to prefrance . Thats probably,from memory about 600ml or so.If you overfill the leg ,cut the tip off the fork oil bottle , mark out on a clear piece of fuel hose 110 mm from one end of hose with a permanent marker, attach other end to the tip of the now empty fork oil bottle nipple, squeeze bottle,insert hose down to 110mm mark,take hand pressure off bottle and WWHHAAALLLAAA!!!!!!!!. Magically the excess oil is sucked back up into bottle.....Don't you just love the forces of nature. : ] ride on DB ......Hope this gets you out of trouble ....Flabbycat

SOURCE: how much 5w oil goes into each fork?

Using 5w oil with stock springs, your oil level should be about 100mm from the top with the fork fully compressed, damper rod pushed all the way down, and the spring out. I hope this helps and good luck. Please vote and leave a message.
