Kom ons gooi maar n Honda ook teen Sochiro se wil

Soichiro was a legend, but simultaneously not perfect... for he absolutely despised twostrokes  ;D


Looking again at this gorgeous monster, anyone knows what that aluminium container is post-stinger?
Young lads would say "Catalyst!" these days, but I can't figure out what it is doing there....

My guess is second expansion box with some very fancy tuning length to catch and feed back any wasted fuel. On the 2T exhaust I designed for linear torque I had two chambers for that exact reason. Standard 2T motor I got 21% more power with linear torque curve.

Or to clean up the main chamber to avoid bounce back and get a clean exhaust wave to the exhaust port.

Yeah...…...we all have our problems!!  Sorry for him!

A cup of coffee and the smell of 2-stroke oil in the air = the breakfast of champions!!

I wonder where that gravel road goes? And that, has usually made all the difference. (Apologies to Mr Frost)

The 2stroke has always been seen as the "ungentlemanly" factor in motorcycling, but adored by the power-hungry and the adventurous.

Interesting bit on EFI on 2-strokes 50 years ago ............................... yet it's sold as a new idea on today's KTMs.

Yip...…...take electronics out of the picture then there is very little that is new. Generally old ideas that have been refined.
