Title: Rat Bike Sighting
Post by MMRanch on 10/08/17 at 12:30:56

Here in Lynchburg we had a "Car show" Saturday . Some Really Nice Cars were there !

On the way into the park , up in front of one of the BBQ shops there was this Rat Bike that looked like a decorative piece you might find out in front of a junk yard (Yard-Art) , cool looking collection of parts . 8-)

On my way out of the park ... there was this Rat-Bike , same one--- it had moved !!!
I couldn't hardly believe it ... I chatted with the rider for a while. Come to find out its a Diesel Water Pump Motor . He said when he left Oregon all the part were shinny sanded steel. He cranked it up and it sounded good as any bike I've ever heard . While the motor was idling (600rpm-ish) the tork-converter was tugging on the belt as if to say "Let's Go" ! ;D

There are more pictures of it on the Scavenger Hunt Thread . :)

Yeah, injector lines are visible.
Bet that thing is Hell on chains.
I doubt there's anything in the power train to soak up the punch of the piston coming down.

Next time you find something like that could you Pleeze take more pictures?

Need a video of the thing starting and running.

Well , he was from Oregon , so .... we can try to hunt him down ?

That thing ran nice and smooth , the pulley on the converter was way, way down in the front "V" and the rear pulley was really big with lots of room to shrink . He was ready to leave when I pulled up and ask if I could get the pictures that I did get .
Save the pictures , and super-size them for inspection. I'm glad I could get the pictures that I did get .
Fact is I'd thought of doing the same thing with my old Savage Frame but the only converters I found were for 5-8HP motors like is on my Minnie bike. The converter this feller had looked big enough for 30 or more HP.

Junk-Yard Wars !... ? ::)

We're looking at the little 2 cylinder Caterpillar C0.5. Originally built by Shibaura and sold by Perkins but now marketed by Cat. CVT appears to be a Polaris product.
At .5L speeding citations are of little concern. But he could farm with that thing - plow, pull stumps, haul mother into town. A tad heavy compared to the Kubotas. The engine. Not mother.

So , That engine is only 500cc ? If so , the converter was way, way over size ... :-?

Still it caught my eye as a neat set-up . I'v got a fat tire mini bike with a converter that tops out at 39 mph/gps . I think its 6.5HP ...

A 30 + HP diesel motor might be too much for the converter I've got , it came with a 428 chain sprocket. So what motor would we want for 30+ HP ?

For bike purposes it quickly becomes all about weight. Plenty of 30 hp diesel options, but most would require hydraulic outriggers.
Best option is the 3 cyl 900cc Kubota D902 at 150 lbs (by comparison the CB750 engine/trans pushes 200 lbs.). I've got one in the shop for the next build. Rated at 25 hp. But with the Aisin blower, 30 hp is within reach.
