If i were to change the rear sprocket, to +2 teeth, would that be enough of a difference to ease my wheelies? And if so, how badly would that affect my top end?

Brain trust, go! Thanks in advance

Yes, it would make getting it up easier.

http://www.gearingcommander.com/ indicates that stock gearing is 15/41. That makes 7000rpm in 5th 73mph. Going to 15/43 is a 4.9% change, so you'd be around 7350rpm at 73mph, or 70mph at 7000rpm.

Thanks man, that's helpful. So part of what I'm taking away from this information is, if I did that, since I only cruise at around 66mph, my top end wouldn't be effected at all?

The engine will pretty much feel like you're cruising at 69 when you're going 66.

I can live with that. I sold my zx10r when I bought this dry400sm, so I'm not overly concerned with top speed anymore. Got any recommended brands of sprockets? Or does it really matter?

Should be ok as long as your chain is long enough to work with the bigger sprocket.

For street use I'd suggest a steel rear sprocket. Aluminum is a little lighter, but you'll notice your lighter wallet (they lasted around 5k on my 625SMC) more than the bike. http://www.drivesystemsusa.com/spro...0-pitch-black-steel-rear-sprocket-sku-14203r/ is a very lightweight steel sprocket, but not available in 43, only 38, 39, 41, 44. They're what I would run on my WR and YZ if they were available in the sizes I want, almost as light as aluminum and last way longer.
