air cooled = 32:1
water cooled = 40:1

so for you 40:1 is ideal

Interesting ..... all of the bikes I have had in the owners / service manual recommend 32:1, but then again I have ran as thick as 20:1 and as thin as 50:1 as per the oil recommendation.

Never saw a 40:1....

Thanks
Scott

@scott: i run 40:1, its in the middle of everything so its just about right, sometimes the mixture is wrong so it gives you some room for error since you can run it slightly leaner or richer because of mixing it not as specific if you could be and you dont end up running to lean or to rich.
keep running it 40:1 dude your doin good so far, get some pics up!
