..too many bikers around here have meth injection as it is. Seems to make them go faster for a while...



Yeah, that's what the old Vincent motor looked like to me, aircraft engine jugs.



Would be sweet.

A giant ship diesel -- or any diesel for that matter -- relies on the heat of compression to ignite the fuel mixture, so for all intents and purposes, ignition occurs everywhere in the combustion chamber at the same time. With spark ignition, ignition occurs at the sparkplug and then has to travel from there throughout the rest of the combustion chamber. With that single (or double, with twin plugs) point of ignition, the bigger the combustion chamber, the harder it is to burn the whole mixture.

You know, I like it! Why not just mount the whole R-4360 on a bike. Now that would be a REAL roaddog! Watch out, Bill Gelbke!

Well, they wouldn't need a "vibe-rider".

If Red Sovine were not dead, he could do a song: "I'm a believer, I got the V-Twin Freightliner Fever"...

I saw a picture of a chopper that had a small radial aircraft engine on it recently...



VERY cool!

Read an article of an Australian that shaved two cylinders of a WWII Rolls Royce aircraft engine.



Ended up displacing 5 liters with 4 valve per cylinder, dohc watercooled vTwin



I am sure it had decent throttle response

Yeah, diesels! Think of the possibilities- a Cat V16-equipped cruiser and a 300+ section rear tire would make yer average Boss Hoss look small enough to make its owner green, eh?
