I'M PUTTING NEW SPROCKETS ON MY 400 AND WAS THINKING ABOUT GOING 15.37. I RIDE TIGHT WOODS MOST OF THE TIME. WILL THIS HELP THE LOW AND MIDRANGE? ANY OTHER SUGGESTIONS?

 

Stay with a 38 rear. Go to a 14 or even 13 on front,mine with a 14 still goes 66 mph so you might like a 13. My opinion is go with sidewinder, they are absoulutely the best and they will make any size sprocket for you, they will be the last sprockets you buy!
