Well I picked up a cr ignition. Had one on my 330. Now I only have a 250. Didn't need that much power. I ride really tight woods. Any how the one thing I hated about the cr ignition was I lost the ability to lug. Was wondering what weight flywheel to get. Was thinking 14or 12oz. Anyone have any experience running a flywheel weight. I ran a 11oz on my RM
