Hey all, searched before I posted this cant seem to find anyone with same problem. .Flywheel weight (steahly 10oz) threads on just fine. when I try to put special nut on that comes with it seems way to small. Called steahly about the thread pitch they said 1.25 checked nut its 1.25. threads on rod are fine, not the best mechanic but figured this was a no brainer.... stumped. Any thoughts? Could steahly have sent wrong nut? Believe its a 12mm. 2003 rm 250. Funniest woods bike ive ever owned, but dam it needs this weight. Help!
