Yep, I just wanted to check and see if anyone had tried another bike's stocker as a cheaper option.
M'boy had an R6 throttle tube ('03, I think) lying around to put on one of his own bikes, so I nicked it. It works with no modification at all (just loosening up the thottle cable a bit). It's about 1/6 turn now. I highly recommend it!
Funny how the Yammy throttles work on other bikes, R1 tube turns a 600RR into a 1/4 turn. Thanks for posting about this, R6 throttle tubes can be found super cheap, might have to try it on the Baggy.
