    Yeah don't put oil in use vasaline. Just heat it up on the stove and pour down each fork leg. Maybe put in a few drops of eucalyptus oil as well then your bike has less chance of catching the flue this winter.

    No seriously what you should do is splash out on a new ohlins front end. I know I would if I wasn't so broke.

    Amount of fork oil isn't a big issue just as long as the same amount is in each leg. Take the caps off remove the springs and bottom out the suspension. Then pour some in each leg till the oil is around (around 160mm for my SV which has similar forks) from the top (Measure with a 150mm rule or just a stick) then lift the suspension to top it out put the springs back and replace the caps.

    Sorry Drew, just noticed this thread.

    434cc oil.

    With the fork fully compressed, measure 138mm below the top of the inner fork tube.
    And I to my motorcycle parked like the soul of the junkyard. Restored, a bicycle fleshed with power, and tore off. Up Highway 106 continually drunk on the wind in my mouth. Wringing the handlebar for speed, wild to be wreckage forever.

    yEP THOSE WILL WORK FINE BUT ABOUT 100YEARS AGO WHEN I RACED ONE WE USED 10WT OIL AND FILLED IT TO 125MM GAP WITHOUT THE SPRINGS AND THE FORKS FULLY COMPRESSED. IT GAVE THEM MUCH BETTER MID CORNER HANDLING.

    EH? WHAT ARE YOU ON? IT MAKES A HELL OF A DIFFERENCE. THINK OF IT LIKE AN EXTRA SPRING IF YA REDUCE THE AIR GAP YOU NEED MORE FORCE TO COMPRESS THE LESS VOLUME OF AIR. iTS SIMPLE PHYSICS.
