Yes Banshee Hill is a bunny slope but the main hill is no joke at Dumont. It's not a sand mountain but it can hold its own. Comp hill at Glamis is a joke now, it has a plateau in the middle of its face. I always enjoy Olds though. The top end is apart right now getting fresh nikasil from Millennium, new pistons and domes from Kevin. I'm going to go with the +10 and try adjusting the spring tension on the clutch. What's a good starting point for spring tension on the clutch? Should I ground the bolts then back them out a turn at a time? Btw my slingshot only has one ball in each slot...
