VERY interesting! Looks like a "Plug-and-play" solution for the existing engine. Wonder what such a modification would cost if you'd buy it from him for your own bike...

Coincidentally, I've seen the 3D print model shown there before. But I think it's still a long way to get it save and
sound and steady.

Since it would only bring benefits in the upper rpm range, I'm not so much interested. But it could be something for
your Sulzbacher though ...

hi, the thing is twin plugging helps loads at the bottom end especially on guzzi and BMW I know because I have both. Not sure on a triple but I'd suggest it's an improvement on standard. Regards Andy

Andy,
this is about a 4-valve project head. AFAIK this head has one plug / cylinder.
Or did I get you wrong?

Cheers
Jo

I was there when Doug Home put Marty's twin-plug bike on the dino and it didnt make big numbers, low 80s hp. And I rode it for a day a while ago and it's surprisingly bloody fast. It apparently has heaps of toque, it did move out for sure. It's an impressive bike all round. Not a lot of room for another plug with all those valves
