Be careful with the machine shops as many don't get many MC motors and there are numerous posts about fouled up results. Maybe put in writing exactly what you want them to do and communicate that so there is no misunderstanding.
Guys have had tolerances way out of spec on boring work and had to start over with new cylinders...things like that. HondaMan has had to train a few shops on what he has been looking for...
Just a word to the wise. Good Luck! People here can help you with questions. Start a thread and ask away, no such thing as a stupid question.
