so im thinkin about changing my sprockets from stock 17,40 to 16,42 OR 17,42. i ride 08 zx10. just wanna see what people think about dropping the front. ive heard that its not a good idea cuz of less sprocket to chain contact. so is 1 tooth down still ok? mainly asking because a few years ago i broke a front sprocket on my 636 that i dropped 1 tooth from stock.
