The Boremaster is hands-down the best motorcycle cylinder boring bar ever. I've had 2 (one new, one very used) and they were one of the best money makers in the shop. During the off-season in Minnesota I'd buy overbored-out cylinders (cheap or free), re-sleeve them, and they sold like candy come spring.
This one has everything needed (hones, micrometers, fixtures) to do 2T or 4T cylinders from start to finish excluding a port chamfering tool. If this was in Phoenix, I'd have it already:

I have a Boremaster and agreed it's a great machine. That's a good price too.
I saw that, tempting, 1.5 hour drive.
For those who have not experienced the joy and happiness of doing a successful bore job, here is a slightly tedious Boremaster how-to:
