Project Moutain Scoot started, found a couple of 2.52 drivers off of a 1980 Yamaha Enticer, 7/8 square drive - same as Scoot. Looking for 1 1/4 - 121 track & rails. Might use a set of rails off of an Indy that are laying around. We measured a track on a Snow Hawk today, might need to get different drivers if we go that route. Anybody know what pitch Snow Hawk uses on there tracks?
