Bike Engine Price

[devino246]

How much do you guys think i could find a decent bike engine for? Im looking at the prices of parts for my ungoverned clone($200) and thinking a could probably get a better bike engine for that. Now i see why your always saying, get a bike engine.

depending on the cc your looking at. You can pick up engines in good condition from 100 up. You will get a nice working bike engine for 450 up and will have plenty of power

I'd suggest you start watching your local craigslist ads for a complete motorcycle that's been in a wreck and had front end damage. You might actually find one of these at a lower price than just the engine, and you'll be sure of getting all the correct accessories you need like wiring harness ignition coils, air cleaners, throttle/clutch cables, exhaust, etcetera.

When you buy just the engine you don't really have any way of firing it up to test it out and just have to take the sellers word that it still ran fine and didn't smoke or have any other issues when removed. You also gotta figure that if the bike was wrecked, it was probably running alright at that time. You'll also get a title that'll kinda help prove its not just some stolen motor the cops are still looking for....

You might also end up with some other spare parts off the motorcycle you could use on your kart. Some guys end up installing motorcycle disk brake setups, lights horns and switches. After your done striping it of everything you want you might be able to resell the rest.

If your patient you can find some amazing deals. I bought a KZ400 last year, with a little under 9000 miles on it, for $40. It was a 1978, and was last inspected in the late 1980s, just needed carbs cleaned and a new coil, other than that the bike was nearly 100% complete and in great shape.

I was thinking of a dirtbike engine. I dont know alot about 2-strokes. How many CCs would something around 8hp be?

 

[Kaptain Krunch]

like 50cc haha, a 80cc two stroke moto cross engine is generally rated at around 20hp stock, and mods/performance parts are unlimited. 125cc two stroke moto cross bikes generally produce between 30-35hp stock.

For a fun kart i would go with a 250cc four stroke, it will be more than enough.

Holy S&#T!

Holy S&#T!

and now you see why everyone loves two strokes, and bike engines. The power to weight ratio of a two stroke is awesome.

Also, a key in the power of those motor cross engines is the fact that there liquid cooled, and have good tuned pipes stock (which can be further upgraded for MORE power).

 

[devino246]

So most of these would have a radiator? Craigslist doesnt yeild much, not that many dirtbikes and such around here. Anyone got one there wanting to sell?

 

[Kaptain Krunch]

Many modern bikes are liquid cooled and have rads, just about all motor cross bikes are. Personally if i were you i'd looked for an old street bike, they can generally be had cheaper.

 

[devino246]

Is mounting these engines much different from industrial engines?

 

[Kaptain Krunch]

Kinda of, normally have to fabricate a cradle, or just cut the part of the frame it bolts to, and weld it onto your kart frame.
