Briggs powered Panther

[chainmaker]

Here is the bike I've been slowly tinkering on. it is still a work in progress hopefully will be done for riding season.

1950 Schwinn Panther - Felt Abraham linkage forks - 19 inch moped rims - Motobecane AV88 rear hub- Sturmey 90 mm Dymo hub - Spokes tires and tubes should be here this week. Wheels may seem overkill to some but my favorite riding roads were originally laid out in the 1700s and 4 inch potholes aren't uncommon and I will feel a bit more comfortable with moped/ light motorcycle wheels. Ordered 19 x 2.25 for the front and 19x2.5 for the rear which is going final belt drive. Whizzer sheave is sitting here waiting.

I'm using a 3 hp Briggs I/C -build in progress/ cam is at Dymocams for a special grind, exhaust springs in and out, billet flywheel, 5 hp flo-jet Briggs carb,

The motor as I received it

Motor is taken apart, did a port on intake, got rid of the threads for exhaust and did a nice polish... am going with a header here. This is about all I can do with this motor as there aren't any billet rods or dippers available. Stock failure at about 6500 rpm. I will enlarge the oil hole, smooth the casting seam and that's about it. That's why the 5 hp carb..don't want to tempt myself. The motor is in the basement will take some pics tomorrow.

Trimmed up the fins for better look than the blocky stock head. Jackshaft mount plate just about done. Scrap will be used for motor mount.

And the insides, the block is going out to have some valve spring pockets put in. Using exhaust springs on intake and exhaust, 5 hp lifters, 94 ss cam, billet flywheel, and some nos Briggs parts.

That's one keck of a project you have going there! Did you do the machining yourself?

Since it's in the Whizzer forum that means now you have to put a Whizzer engine in it.

Been busY with some other stuff lately. New seat came ( black one on right). Block work...pockets for oversized springs and 5 hp lifters, valve grind, and head cut. Changing jackshaft mount still need to shape mounting plate. Scored a rear fender with drop stand.
