That was a while back (May), but the JJ did'nt exist then...
I thought you guys could appreciate this item I scored:



What is fascinating to me, is that:

1 - The need for speed is such, that guys would want to Hot Rod a 138cc, 2.5 HP motorbike???

2 - That a company would oblige, and produce speed parts for a 138cc, 2.5 HP motorbike (a hot cam, larger valves and a re-worked Tillotson carb where available).

The head is cast in bronze.
(probably Herculoy™ or Everdur™ = a silicon-rich bronze alloy).
The compression area was re-shaped for better compression.
The casting is kinda crude, specially compared with Whizzer, die-cast quality.

Here is one cleaned-up and mounted on a 1947 'H' motor:

Great looking Bike. The bike shop that I worked at in the early 70's had been around since the 20's and in the 50's made speed equipment for the Harley 125's. Theres always the need for More Speed!.. Good Score.
