May 14, 200917 yr Glad I could be off assistance there Glen Could you not just stick a 428 chain right onto the narrow sprockets?That's what we used to do to get mud to evacuate back before "Sidewinder" style sprockets(Ok,it was just because we'd steal Dad's spare chain fer his big bike when ours jumped the sprockets and mangled up) I've also turned sprocket thickness down on a brake lathe(had a bunch of 530 sprockets,needed 520) Would it help the 4 ply tires to "sipe" the tread?(not for when your daughter rides it,for when you sneak a ride)
May 15, 200917 yr Author I may try a 420 chain , as a 428 leaves a whole lot of space , and both tires are already siped ... I may customize them a bit more ....... I'm still waiting to hear about a stock countershaft , as a shop in france list a 428 counter but not a rear . so if I can set it up stock for now , I can get sprockets made in the futurre. I mean really, the OE. stuff lasted this long with little or no maintenance ... And i've got to wire in the late model coil this weekend and fire the little beastie back up ! Then pull the exhaust off and clean it all out and repack it . Or find a modern silencer/sparkarrester that can be made to work ... The life of a trials dad , never a dull moment ! Glenn
