    Is he running a CVT clutch/transmission there? I see some big pulleys. And 104 mpg! He's doing something right.

    I see he put up a website/forum but the most recent post on it was a year ago. I think that photo of the grinning toothless motorcyclist must have scared everybody. I wish I could unsee that!

    Looks like the same variable-diameter pulley drive system the original lawn tractor (or perhaps a snowmobile?) may have had. Also, note that he says he's driven over 7000 miles, with an avg of 115 mpg!

    I like old bikes, but I have to admit I'm not real fond of those 4-carb engines. My son had one very similar to the one pictured, just a bit larger- a 1979 GS1000. That diesel conversion sounds very interesting!

    I wonder what his 1/4 mile times are now. that was probably originally a 12 sec. bike.

    Very cool! It actually sounds pretty good too... and great diesel smoke under load . The diesel motorcycle thing seems to be really taking off. There are a lot of videos on YouTube now. I had no idea.
