Insane Honda Big Wheel

[ddemair]

The Honda CB750 is an air-cooled, transverse, in-line-four-cylinder-engine motorcycle made by Honda over several generations for year models 1969–2003.

I think The GSX 1100 is water cooled. I guess it depends which year.

It also had a dry sump, which is why STRider asked about the oil tank/reservoir.

The engine in the photo with the fine pitch cooling fins is air-oil cooled and would need an oil cooler approaching the size a similar water-cooled bike would use. Suzuki switched to full water cooling in 1993.

Right but I think that was up until 1979? when they went wet sump. On the motor in question the oil reservoir the would have been on the right side IIRC. Not that it had to stay there on a custom on-off. But gravity fed that would probably be the best location.

I want someone to put an ST engine in either a big wheel or that monkey bike. Let's quit pussy footing around with a 450cc inline 4 and get some real longevity on one of these. Let's give Allan Millyard something he can sink his teeth into.

Yes, with the '79 DOHC engine.

Yeah, yeah; but what brand of oil does it use?
