Looks like someone has the answer for you Reep.
Out here where I'm at in the Los Angeles area, Pat the Machinist as he is known works out of his house. He had a shop years ago and used to race and all that good stuff. He builds engines of all sizes for bikes.
My ace in the hole was when Pasadena City college had a Motorcycle Mechanics class. We had all the good equipment plus a new boring bar. The was the greatest toy around!
Unfortunately this unique program was discontinued due to "funding" issues. (They felt the money was better spent on English as a Second Language classes) The end of an era for me, but now I'm not affraid to pick up top ender cases with Pat around.
Hopefully there's someone like that in your neck of the woods.
