Point is...that no one ever thought that a 4-stroke would be competitive (in the rules as written) until first Husqvarna, then Yamaha did it. Who is to say that given the right situation (under the rules) a diesel or even steam engine! wouldn't be competive?

All it takes is putting pen to paper and everything we know about motocross could change forever!

Diesels can be either 2 or 4 stroke and the Jimmies were 2T with port intake/poppet valve exhaust (supercharged to get the hole thing going).

Just saying I'd rather go diesel than electric. What I'm really looking forward to is a DI 2T.

Detroit's were as you say PLUS a turbo charger. Smokes more than a two stroke bike! makes a very cool sound. That said, the paraphernalia needed to make a diesel make power makes them heavy. That 20:1+ compression ratio takes some serious strength. This is not a problem for ships, trains and big rigs in that the load is so much heavier than the power plant. Not so with a race bike. I don't think its viable for a MX'er for this reason alone. But they are cool engines.

I saw a fire truck on the side of the road about a year ago for sale. Was a model that had a Detroit in it. Was all I could do (and my wife could do) to keep from pulling over and buying it on the spot. ;-)

i'm still toying with the idea of a snowmobile engine in a rear engined bug chassis...

I would love to stick an eTec 800 into a Datsun 240Z. Should be pretty easy to hitch up the CVT drive output to the drive shaft (I think it would be harder in a rear, or front, transaxle drive).

I'd love to build a 320lb Etec 800 dual sport, kind of a super BMW GS800.

I sure like the sounds emanating from that Detroit pick up!

i've always been a huge fan of single-sided swingarms. And i've hoped for (in vain) single-sided front suspension to appear on bikes. Not talking about hub center steering, but a single fork that wraps around to a large hub on one side. So my dream is a motocross bike with single-sided suspension front and rear. Cool looks and easy to work on. And different

My other day dream is a big bore DI 2 stroke with a rear exiting exhaust. The frame down tubes would part to accomodate the fatty part of the chamber. Since the entire "carburetion" takes place at the top of the cylinder head, there would be a simple intake design in front of the cylinder to channel air into the relocated reed valve.

Looks like the Big Red FI vendor (of CR500 in a YZ450 chassis) is building another bike. This time the CR500FI is in a CRF250 chassis. No details yet...
