Sprocket size

[Stock 400 rider]

Hey I'm running the cross country here with my 400 EX completely stock, even the sprockets.(15/38)
I need to know what size is the best for
1- a holeshot/tight courses with low to mid speeds
2-courses with a good final speed, high speed courses.

Thanks a lot!!!

id run a 14 tooth front ......and the stock 15 for the more higher end speed courses

Yeah You prolly better bump down to 14 tooth....

Running stock size tires..leave the stock sprockets on there..if ya run 22's out back drop to a 14...at least that's what i do...and while i'm at it..i'll go ahead and move this over to the correct forum...;)

That's the only thing I hvae to do?
Don't need to do nothing with the rear?
This should be fine cause that's one thing that I don't have to buy
