Some pics of my flywheel findings - with further mods this weekend Carb, timing and ignition "settings" bike now revs out much better and am liking the lighter weight much more than last time I rode with it. Was too stally and weak feeling. Am still going to make one with in between weight (I like the sound of Burgat recommendation of 800g? removed in a previous post I read) Grip is affected but nothing that throttle control and body engish shouldnt sort.
Best wishes
