Post V-8 Motor Cycle Engine

A few years ago I was reading a Circle Track magazine and ran across an article about a group of people who were making v-8 motors from two four cylinder motorcycle motors. I haven't been able to find anything since. I want to build one of these and stuff it in a larger bike or a legend street car. Can anyone help me find out how to do this?

I have not seen what you are talking about, but I have seen a Chevy 350 V- 8 engine tucked in a Harley that looked like it came from the factory that way. That might be easier to do than putting 2 four cylinder motors in there.

Hey Larry, V-8 scooters are no dream man, they're a reality!

R.C. Collins ( abig motorcycle cam guy) built an engine like that in the '70's for drag racing, it was basically 2 750 Honda topends on a common block/crank. I haven't heard of any others in that vein, MV Augusta made a road racing V8 bike in the '60's, but they are rare and $$$$$. Those V8 chevy bikes are showy but don't have any of the characteristics that make a motorcycle fun, handling, maneuverability and braking, if it should go over on you be prepared to call a tow truck. Really like a 2 wheeled car, will probably get you looks but if you want a motorcycle will get old quick,

I see a lot of those V8 bikes here in Florida. The most common are "Boss Hoss" they retail for around $40k, but can be had for about 1/2 that a year or two old. Does that tell you something? Woods428 is correct, they handle like crap.

It looks like a good bike but the speed is only
theoretical. The Widowmaker was a cool bike it ran 10.60s. Just think if they could have hooked it up. I wouldnt mind trying out the V10 but the only place you could go that speed on that bike is on the salt flats. I've gone 9.20s and what a rush on my bike. Life begans at 150

i happened to see a simmilar program, it was about some crazy brits who made a 2L v8 out of two yamaha 1000cc inline fours (you know the 5 valve 1000 found in an R1) only the block and crank were home made, everything else was yamaha, they also sold the engine to someone who made a car called Rocket (rocket light car company i think the companys name was) and it was about the coolest ride ive ever seen, it was a 1950īs formula one design singleseater that weighed 600 pounds and had that 320 Hp 2L v8, guess why they called it a rocket... and the coolest thing was that the car was street legal in britain, but go figure britain is the country where you can own and drive a sherman tank on the roads, if you are willing to pay the gas and insurance
