Ah, the soft farting of a diesel engine - in a motorcycle! Now that makes for some cool idling at a stop light!
“Worst mental image of the day” award.
The Cummins engine that Dodge used, when uncorked (as so many Dodges were for some bizare reason I'll never figure out) sound EXACTLY like a giant, just won the weiner slamming championship fart. Other than that, I don't see why they couldn't build a viable diesel ride. Yanmar has been building diesel outboards for many years.
