Largest front and rear sprocket for speed

[asleepz]

Alright, just doing some planning for my "new" 06 300ex. Looking for mainly a bit of speed since I've got a lot of flat land out here.

Theoretically what is the fastest sprocket combo you would suggest with Uni filter, modified air box, curtis sparks full system and rejetted..

And would it be worth getting a rev box? It seems like the bike doesn't make much power up there anyways.

with that set-up, and assuming it has 22 rear tires i probably wouldnt run past 14/38

thats one up on the front and stock rear,

if you feel like you need the additional rpm's in the top end then id suggest a rev-box, but make sure you get a good one, those cheap ones cuse more problems (starting) then they do good,
if not spend your money else where, where it could make an improvement

but with that particular engine set-up i dont think your gonna need it

Yeah, I'm still running the stock 22" tires.. But when they go out and I get 20"s what would be your suggestion then?

id still try the 14 front, and see how ya like it, if you feel liek you need more, and you think your engine can pull it then go for
14/37

when you get the 14 get your grinder out for your case saver.

I am looking for a 35ish rear if anyone knows where to get one.

Im guessing it's a tight fit?
