Hey dude,
Anyway, you can get a can at these places:
www.pipecity.com
or
www.starcycle.com
They have pretty decent prices.
I was just curious if you knew but, you do know that 190(I assume mph) is gsx1300r(aka: hayabusa) territory, right? The top speed is around 196+ for the pre-2000 models and after that, it was limited to 189mph. And the gixxer 1000 since 2000(I think), the speedo is limited to 186mph. And if you did go up to 190mph, take away about 5-10% and that'll be your true mph. Did you add a tre to eliminate the limit? If you did, that's freakin' insane dude. I would NEVER go that fast on public roads. I've done it at the track though.
