Milling an RD400 head
« on: April 16, 2019, 12:50:21 PM »
What is the recommended amount to mill off an RD400 head, for street use. It's not a race bike. I have heard .003". Is that correct?

Hi, What thickness is your head gasket ?
There used to be 2 avaiable, .5 an 1mm,
I used to fit the .5 when tuning the 400.
