Have a WR timed '98 400 with a lot of the mods presented on this post. Current gearing is 13 front and 49 rear. Consistent problem is that I stall the bike coming into turns and such. I know that this is partially due to my riding (using clutch, staying on the gas, etc....). I have been thinking about re-gearing to 13-51 or 52 because I don't need the top end as much as I love the bottom end. Plus I think that it will be alot better for me where I ride. Question is, will this change result in me stalling more/less or no effect?
