Building a rotary-powered bike??

[colt45]

I have a plan to start a long project involving two of these engines, http://www.wankel-ag.de/lcrkart_e.html or two of these http://www.nova-racing.com/nova_gb/index.htm.
and getting them turned into a two-rotor engine, one of these engines produce about 48hp, and with some port work, i'd love to do PERIPHERAL, but most likely BRIDGE, hopefully it should put out 100hp+, finding a gearbox i can match to it and i will need to either modify an existing frame, most likely a two-stroke rgv/nsr frame, or get one exclusively made.

What do you think of this?? i know there is the norton f1 but that is horrible.

The engine can be done at www.res.co.nz

Huh? The norton is a beautiful engine. Designed in the late 1970's and the engine is still used today in light aircraft and US military drones.

I notice that both the engines you refer to are listed as 4 stroke rotary. How on earth can a rotary be a 4 stroke?

Um, you have posted this question twice: Which thread do you want the answers to appear on?

hey someone built a project bike using the 13b rotary with turbo, it was a trike and i think its still on trade me

That's something I'd like to do too. However I'll focus on the immediate plan of maintaining the bike I currently own first. You'd do better to build one out a rotax engine. Heaps more power and better delivery.

Or get one already built. http://www.rotaryrecycle.net

It a good idea though. Just be aware of the costs - it aint cheap to build a bike from scratch. Even if you have a frame and a whole lot of bits (engine etc) you'd still have to get the frame strengthened (or at least) certified...

[colt45]

But where is the fun? i could just turbo charge a two stroke but i love the dirty sound of the rotary, and the rotax engines aren't as powerful, and won't rev to 11000, and this would be a lot more fun.

Before Van Veen built the OCR1000 he made a prototype using a 10a or 12a in a modified MotoGuzzi V7 frame using the Guzzi Gearbox.

I doubt it would fit into a RGV frame let alone the major problem of a transmission.

Building a frame or machining the parts is simply a matter of having the skills and access to the tools/machinery needed.

How on earth can a rotary be a 4 stroke?

intake/compression/combustion/exhaust -4 strokes

[Jantar]

intake/compression/combustion/exhaust -4 strokes

Yes, a rotary and a 2 stroke have intake/compression/combustion/exhaust phases, but not on seperate strokes of the piston. Indeed a rotary has no strokes, but completes all phases on one rotation of the crackshaft, or on 1/3 of a rotation of the rotor. So its a no stroke.

[onearmedbandit]

4 strokes have '4' strokes of the conrod for each firing stroke, 2 stroke '2' strokes for each firing stroke. 'intake/compression/combustion/exhaust' is what all petrol engines do, it has nothing to do with '4 stroke'. I agree with Jantar

[Jeaves]

intake/compression/combustion/exhaust -4 strokes

Compression and combustion are on the same stroke/rotation .

i jsut watch suzuki RE5 intro movie and he explains the 4-strokes,

nowing my luck im probably wrong so il just say either way who cares, good lcuk with ur project seems a bit DREAMY to me though
aint saying cant be done
