To Mill Or Not to Mill?
« on: February 03, 2003, 06:16:56 pm »
Is milling of the head allowed in supersport? I am not the smartest person in the world, so I can't really figure out what the rule book says is ok. Sorry again for yet one more newbie question???

If it is not legal, a large portion of the grid would have to be disqualified

ANd actually you don't want to mill. What you want to do is grind your cylinder head. It produces a better finish, & provides a superior sealing surface.

And you'll HAVE to reset the cam timing because the distance between the cams and the crank will change if you do any cutting of the cylinder deck, cases, or head.

Matt,
What are you using to grind the head with, the image in my head is grim.  I picture someone with a grinder.  I'm not be sarcastic, I'm actually curious.

I of course don't do the heads in shop. Although i have a local proffesional that I subcontract with to do that type of precision machining.

I do know that there are several different types of machine that are used for grinding. The particular one that is used for my work, I do not know. I was just happy at the quality surface finish that was produced.

Here is a link to my website with some pictures of a finished surface.
