front fork spacers 89

[coops]

Hi, wanna harden up front end for track bike. Stock forks seem a little soft at mo. (im quite heavey, 110kg, tall, not fat ) Maybe do a complete valve, spring rebuild next year but thought id just lengthen the spacer on top of the spring, an inch or so and new oil, get me though this season.
Havent opened them up yet, just looking at my parts book.
Any suggestions on length or whatever appreciated.
