No problem at all. The Wilbers fork springs are a nice match the Wilbers rear. Wilbers recommend using 15wt fork oil with their springs, however I chose to use either 10wt or 12.5 wt instead (I can't remember). The roads up here in New England are not the smoothest, which was why I decided against the heavy oil. The only other thing I can think of adding in the future are the Race Tech fork emulators.
Geoff, who did you buy the fork springs from? Apparently it was not Affordable Beemer Services.
92 K75s (never sell), 97 F650st (sold), 04 R1100s (now owned by a deer), and about 10 others
