Where can I get my gear dog undercut?

I know of no one on this side of the border but http://www.fastbygast.com/ is not far away (Buffalo).
Make sure you are actually solving the problem you intend to be solving and not something else. Undercutting removes material from the engagement dogs and doing so CAN weaken them.

Those look OK from here. Were there issues with the transmission? (don't fix stuff that is not broke)
You also need to inspect the mating slots in the adjacent gears and check that the shift forks are moving the gears properly into full engagement. On this end of the internet, the engagement dogs look like they still have as-cast surfaces, which is indicative of very little wear.

I open the thread before seing my transmission.
I recently bought the bike with lots of spare. It looks like the spare transmission is better, no wear.
I was just told by the PO that it has issues during hard acceleration in 2nd gear. I will do further inspection. Thanks

We used to undercut transmission gears when I worked at Niagara Race Crafters back in the 90s. Most gears these days have a factory undercut, you should keep in mind that once you additionally undercut a gear you're through the surface hardening of the dog so you can expect accelerated wear in the future.
Most times you'll need to replace the affected pair of gears (2nd and 6th usually ) the shift fork AND the shift drum because it's pathways are damaged the fork pin forcing it to rotate when the gear disengages.

those pics are of the wrong set of gears. as brian stated, look at the other set, those are the ones that wear.
