Knuckle Guides for 5/16 Valve Stem Now Available

I now have Knucklehead valve guides available for 5/16" valve stem size. This makes switching to a bigger intake valve on a Knuckle easier, since you can use readily available Sportster intake valves (1.94 or 2.0"). Available in +.002 and +.006, with or without seals.
