Scooter Engines

[jonzer12]

As I am slowly working on my SII buggy I have been toying with all kinds of motor choices.
As I am interested in atv trail riding only and am only looking for a top speed of 40-50mph
I have been looking at either industrial or atv engines so far.

I recently saw this page [url=http://www.suzukicycles.org/Burgman-series/AN650-Burgman.shtml:3boch8ny]Suzuki AN650[/url:3boch8ny] and
began looking at scooters. *They have terrible resale value and are easy to pick up cheap. *This suziki 650 has 50hp and CVT drivetrain,
which is what I want. *I was thinking about maybe picking up something like this and putting it through a polaris ATV tranmission using a jackshaft.
Anyone know anything about these engines? *I have never driven a scooter but 50hp is plenty for what I want.

I believe that engine is a laydown design, making the entire assembly very long, compared to a normal inline 2-3-4 cyl MC powerplant. Perhaps too long to fit in a minibuggy- Other than that a nice engine.

Found a pic of one


Maybe mount it like this: (thank you YoshiCAD * )



Instead of the chain/sprocket use a reverse chaincase from a snowmobile

Actually not a bad idea. Nice looking motor, even has a heat exchanger before the oil filter.

With a 524# dry wieght for the scooter the trans should be plenty strong for a single seat buggy when gear correctly.

Wait, wait, wait....... I see 2 starter motors on that thing. Do they have electric reverse also?

bdkw,
I think these have an electric push button gearshift, meaning the CVT changes ratio when you click a button on the left handlebar. Thats maybe what the 2nd motor is for.

EDIT:

This pic shows how the electric motor controls the CVT

EDIT II:

Even better, heres an animiation showing how it all works:

those are to adjust the cvt ratio......I thought the same thing but it apears they are not in line between the power and the ground.

Scooter engines would be a good choice. *I haven't seen any whole scooters that are too cheap though, and for the same price might be able to get a whole quad instead. *The other option is the Honda Silverwing. *That has a more standard CVT setup, but the crank is splined instead of taper or keyed so you need an adapter to run a different primary clutch. *A few years ago when I was in school the snowmobile team used the Silverwing engine in a sled with a turbo, made around 80hp and was pretty reliable. *I put a pic on here before...here it is:

Well I saw a running AN650 go for $670 at salvage auction. *Took a little front hit and the side was scratched but according to the description it ran fine.
It only had a few k on it and was 2 years old if I recall. *Practicallly brand new.
I did some further reading tho. *The Suzuki will run like a normal CVT and has preset "gears", not too sure how useful that is.
There is also tons of other electronics to deal with. *I don't want to get into that so maybe a Honda would be a better bet.
I didn't forsee the "laydown" design. *I think the comment *on it being a bit long is right. *In my application the more compact the
better. *Still if I see another salvage bargain like that I might just pull the trigger and see what happens.
