Thanks for the info.

 

The stacks are from PJMotorsports@frontier.com

item# pjm-vs4 $29.95 each (they need to be lacquered or anodized but are a perfect fit)

 

The filters are K&N RA-050V (these offer maximum size with clearance all around.)

 

They are fit together by flattening the rolled edge of the velocity stack (mostly for looks) and drilling many 1/16 holes on the flat of the filter to create a mechanical bond for epoxy. They are simple slip fit as I chose to leave the filter neck on to have more bonding area and wanted an easy and positive fit. I know that there will be folks who will rightly poo-poo the underutilization of the flow of stack, to them I say "meh".

 

The sender is from S and S Classics and is a V-Three unit that has 3 wires 8 pulses and work with almost every electric speedo including VDO. It needed a thread bushing adaptor I had to make ( I couldn't find it anywhere) 7/8-mpt to M16-1.0 to mate to the Motoguzzi output. It also needed the drive key lengthened by 3mm which was done with a TIG and filed back to shape.

Nice setup. Did you have the stacks milled, or are these available? If so, details pls, including the K&N pds.
