Diesel Bikes - why don't they exist?

[Blazinjr]

This is not diesel related but has anyone ever swapped a 2 stroke engine into a GS frame?  There are a ton of Aftermarket stuff for the 350 Banshee twin engines and they are 6 speeds also.  Stock they have about the same HP as ours does stock.

if anyone does get ahold of one of these desiel bikes they could run used vegitable oil such as they do in cars. http://www.greasecar.com/   thats basically free fuel. bio desiel is cool but not free and the govt only pays for half of what you spend . resteraunts pay to have there greece hauled off, make a contract with one , supply barrals, then bring it home with you, filter it out then use it. basically free.
