sender and velocity stack.jpg

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

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 inside diameter of the pod neck is still larger than the i.d. of the stack)

 

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.

Thanks for the info.

The adaptor I made using an older style spark plug that I tapped to fit the guzzi threads.

Just recreated these and super good fit.  I did something a little different here.  I removed as much of the inner collar from the K&N and then secured with springs.  Four pin holes and the springs clamp the filter down tight.

Just got out for a quick ride up and down I20.  Wow this thing pulls to rec limiter.   Really nice and much smoother than pods fitted directly on the throttle bodies.  The left side is tight but I'm VERY PLEASED.

 

Thanks for putting this info up guys.
