What would you do? I would like a more stable bottom end on our WR426 (I can handle the bike, but every visitor who rides it ends up stalling it while we're out on the trail). I'm thinking either up a tooth on the rear, or a new flywheel. I don't know anything about the flywheel costs, and I don't think I'd want to do that myself. What have/would you do? I'm currently running stock gearing on the bike.
