Well when I took apart my timing sprocket etc last week to fix the broken keyway I apparently lost the crankbolt that usually holds the sprocket on. Anyone know the size that this bolt is? I know it's a 17mm head.
If I remember right, that bolt has a pretty special shape - I think it has a built in flange. Anyway, you should probably just get an OEM replacement. I lost one and was able to order one from the Suzuki parts counter.
