Highwayman Pipe Tuning: exemplified for the Yamaha TD3 250cc twin
Achieving a specific tuning goal with pipe design. The goal was to achieve equal or greater power while moving the red-line from ~13,000 RPM to a max of 11,000 RPM. The pipes on the bike kept wanting to pull way past 11000 RPM, and the owner wanted to keep the power below that to preserve crankshaft life, while not loosing race winning power!

Highwayman HPI ignition systems for the Honda CB160 CB/CL175 CB200 based road racers
Highwayman Bikes is now a official dealer for HPI ignition components.

I offer a high quality, bolt on, low inertia, magneto-CDI racing ignition for the small Honda twin GP200 class road racers! After spending a few years racing GP200 with AHRMA it became apparent that ignition failure was a leading cause of Honda riders missing races. Having had much success adapting HPI ignition components to run on my two stroke racers decided to share the wealth and make a reliable, race-quality, easy starting, high revving system for the Honda twins that wouldn’t miss a beat.
