Have you guys seen the stuff from SMR (sex machine racing)? They do dry clutches and the lot but just look at this case!!!

Just saw this and want to throw in my 2 cents on the original water cooled photo. I think its definitely overkill, people have been building big power air cooled 200-300cc Daytona's without cooling issues only running an oil cooler. Was talking with a guy on FB and he made a good point on the xr650 and how it was one of the best desert bikes ever created and was air cooled. I have always talked crap about air cooled motors but now im thinking its efficiency is a lot better than what i thought.

That watercooled engine is built for a load transporter not for funrides. With those things the asians move loads exceeding the payload of an US 1500series pickup truck. Slow, but it works.

4 valve 50cc is just more steps to make a 49cc...why over complicate it?

 

[nielspbr]

Same principle as the daytona anima 150/190F sohc 4-valve. 3-speed semi box.

 

[50race]

From the looks of the 4V 50cc I think the left engine case could be replaced with non e-start and have a cool engine for a true pit pitbike.

 

[66Cooper]

What kind of HP we talking with that? I guess if you were stuck running 49cc motors in a certain class, this could be cool...though I’d imagine said class would also not allow such a radical departure from the original motor.

Well this monster just popped up..

"Full power engine Flat 4stroke for PITBIKE Honda CRF150R for sale

price 4900€"

This sure is something.

 

[50race]

2009 has some threads here talking about that type of engine.

Italian 220cc. Billet Monster Engine!!!

Just when you thought your Motard was sick... (PICS EURO...

You go and see something like this and it crushes you! Sorry but I don't think there is a Motard in America more bad a$$ than this Bucci Moto. Locals are racing a 4 valve Kitaco KLX 110 motors against this and they said they can't keep up.

If I can throw my hat in thing ring I think we’re looking at this wrong. One of the biggest problems with oil and air cooling is that it requires 2 things: oil pressure and air flow. These little engines are usually in bikes that can and will spend lots of time putting around slow, or sitting in traffic somewhere. Ever been in traffic on an air cooled bike? Not to mention these engines can run real hot. Just my 2 cents tho. Kinda dumb sometimes so take as you will.
