GUIDE +.004 SEALED - KWPM (MNG BRZ)
A .004 in. oversize sealed valve guide in manganese bronze, PN 71-3294/004 (alias 70-0333S).
This is a valve guide finished .004 in. oversize, listed under PN 71-3294/004 with the older alias 70-0333S still turning up in some parts books. The description notes it's a sealed guide and calls out the material as manganese bronze, which is a common choice for valve guides because it holds up to heat and wears evenly against the valve stem.

Oversize guides like this one are used when the original guide bore has worn and been machined out past standard dimension, so a guide cut .004 over brings the fit back to spec. We don't have detail beyond that in our records, so if you're not sure whether .004 over is what your head needs, give us a call before you order and we can sort out fitment.
One of our other catalogs lists this under a valve guide heading tied to the 650/750 twins, which lines up with what's on the part itself, but we'd rather confirm your specific application than guess.
