After 6 years of solo riding at BUB Speedtrials I have decided to double up and turn the XR 500 into a bare knuckle sidecar racer. The foundation is a modified laydown bike, rigid rear, 75” wheelbase, rake 5 ¾” to 7 depending on where you set the tubes in the triple tree. I have looked at the rules, scanned the web, and searched the LR files. I have learned a bit but have just as many questions. Since the bike is a dedicated salt speedster, is 0 toe-in and 0 lean-out preferred? I only need to turn on and off the track. I see some like the outrigger wheel more forward at Bonneville for stability. But how far forward, halfway? The rules require a minimum track of 32”, is there any advantage to make it wider? Since I need to kickstart it on the right side is there any issue about putting the hack on the left? To fit the bike on the trailer I think it will need to be a bolt-on rig. The out wheel should be more than 5” but is there a size that is best for speed-handling? I respect those who have gone before and want to learn from your experience. Thanks.
