Tight woods trails? Sounds fun. 13-47, maybe 13-49, I know alot of guys run taller gears, but that's my gearing unless its open sand on my 250. It doesn't really make it ride wheelies more, just shortens powerband that seems to slow it down. It will actually make it faster, by giving you power in the lower speeds and from turns that you are doing the most. I don't have a flywheel weight. Gearing down helps to keep the bike from stalling also.
