In 1979 Mike Parti and myself ran the first sidecars at Bonneville.....at that time they were the sidecars we used for roadracing.(now our outfits are special build for LSR) we ran with passsengers from 1979 to 1987...then SCTA in their wisdom said "no more passengers" I won't go into all that was involved in that ruling.........
so after that we raced our outfits with a complete passenger platform.....and at times with a dummy called Elmo (that's another story) complete with leathers and helmet.....until our team started racing with BUB.
Regarding the frt. forks..............., we have build streamliner sidecars using leading link forks....we have build rear engine sidecars using cut down tele-forks..presently we are using cut-down Rickman Moto-Cross forks....using a 30 degree rake...........64inch wheel base........32 inch
sidecar (center of rear tire to center of sidecar tire) 13 inch lead of the sidecar spindle over the rear axcle........this appears to be a happy medium
for us.....no secrets. The forks you have on the scrap Buell can be used if shortened (you only need approx. 2 inch travel) Oh, yes, we have used 10 " wheels...13'' 5'' (on the sidecar) we are now using 16" front...15" rear....5" in the chair
After SCTA "outlawed" passengers we ran 150lbs
ballast in the chair at Bonneville to handle the cross winds.....but todate SCTA has not required ballast.....however,Ifeel it would make for a safer sidecar if not using a passenger. ......................
