Who can bore DTB to 64mm?

Postby Hood_Lum » Thu Dec 26, 2013 5:29 pm

Upgraded to skunk2 64mm throttle body.
I can bore out the manifold myself but where can I get the dummy throttle body ported to 64mm?
Went to a couple local machine shops and they all say it's too small and they can't clamp on to it.

How could they not clamp onto it? Most 3 jaw chucks will be able to clamp that size. its not particularly small.. nor big..

Not sure. Took it to 2 machine shop and the told me the same thing.
Called a few motorcycle shops and they don't have the equipment for it either.

I bolted the Skunk t-body on with out the gasket, used a sharpie and colored the excess metal. You are making it too difficult.

The shops sound lazy/like they don't want your business. If they are afraid the wall thickness is too thin to clamp with the 3 jaw, they could always use a 4 jaw on the flange side.

we ended up sorting this out. it wouldn't fit in a lathe. got it on the mill with a boring bar and got it done.
