Go one tooth larger on the front sprocket or two smaller on the rear. You will lose acceleration / bottom end pull.

Taller tires will give you another 1-2mph. 22"

I've been wanting to do the same to mine for a while now. You'll have to post some results if you get to go through with it.

yeah..raise the front sprocket teeth..and lower the rear sprocket teeth..this alone will give you more top end speed..buttttttt..it will lower your take off a tad..not much..i did this on my '86 honda 250 rebel..cept..i just lower'd the rear sprocket for now...i can hit 75 easy now.

dont do 13 36 i did and my chain was tight as a banjo string 14 36 should work well as far as chain tension goes

I think you may be backwards on this one... If you increase the front sprocket size to 14 you will shorten the chain quite a bit. Stock is 13/38 if you raise the front to 14 and leave the rear stock (38) and add the 22" tires you will still retain a pretty decent take-off and gain a couple MPH on the top.

yes but a 14 does not fit comforably grinding the case saver away is needed im told. 13 36 i tried with the stock chain size way too loose. then i removed a link and it was way too tight even with the carrier adjusted slack

I used to run a 14/38 with 22" razrs on my old 300 during the summer, and I just took the case saver off (not recommending this at all). I just checked my chain more often to make sure the chain wasn't too loose or tight. My buddy ran stock gearing with 20" tires on his 300, and I could just barely pull away from him.

Do not go up on the front sprocket. It will become a bigger problem when the chain brakes an blows the side out of your engine.Just change the rear 2 or 3 teeth

I don't have a case saver but I check my chain before during and after riding. you can drop the rear sprocket to a 36 or 35 for more topend like 838XCracer said,

36 would do fine, but any of these tweeks to the gearing won't give you very much top end. Maybe a few mph's but nothing grand.
