This motor or that motor?

Scout · Nov 12, 2013

I've been offered a 500cc two smoke sled engine for $200. It comes with all the parts to run it, been converted to electric start, but has no pipes. How much of a pita is it to build tuned pipes?

I'm torn beween this and a box stock engine. With the box stock motor I'd repower my grasshopper, but with the sled engine I think I'd have to build a new cart. (Or try to repower my old red kart)

i go with the 500cc two stroke sled engine for $200 need more powaw!!!

When you say all parts to run it what is included regarding drivetrain

Scout · Nov 12, 2013

It has both pulleys of the TC, belt, carbs are on it, and the exhaust y pipe. No expansion chamber. I'll need to make a jackshaft and get a sprocket to drive the axle.

After reading some snow powered threads I'm leaning towards sticking with a one lunger.

Well, making an expansion chamber may be a bit difficult but, you have everything else you need , that's a plus isn't it?

I can't acess that link; 403 forbidden...

If you go with the sled option, you will never be at a loss for power. They are beasts! You can probably pick up a used expansion chamber for your motor on a snowmobile site. Since you have the primary and secondary, you have the essential parts. They can be a pain to set up but when you're done, fun,. fun, fun!!! Plus, electric start means lights and accessories.

I clicked on the link and it took me right to it, may not let you because you are in AUS.

It is very tempting to use it, but for now I think I'll pick up a Predator in a couple weeks when they are on sale. Does anyone know much about them? I looked close and it appeared to have plastic fins on the flywheel. What's this "hemi" head? I've seen it referenced here and there, but I don't know if all the motors have it or not, and how does one know? The most I can find is an aftermarket head.

Original Predator is pre-june 2013? After is hemi head version? http://www.affordablegokarts.com/mm...e_Code=A&Product_Code=HG275&Category_Code=PNP

PN# 60636 is for the Hemi head; indentified by the part number or different "square" cast aluminum valve cover.

Scout · Nov 13, 2013

Yeah but I didn't know if the engines came with a hemi head, it looks like the newer ones do. I'm just wondering though, how to tell once I actually buy a predator. I mean it could concievably take 5 months to go from the factory to the store to my hands, if they don't sell many. I'm sure theres a date of manufacture on it or on the literature somewhere.

The BSP motor looks like a good deal, but I'm wondering how much power it makes, compared to starting with a bone stock Predator and building as I go along. I guess as long as I'm more competitive with it than my flatty I'd be happy.

danssoslow · Nov 13, 2013

I'm not absolutely certain that it will be as easy as breaking it down by date. They have been offered for a while now throught the country; but not in California. It has been assumed that it isn't smog legal there. On top of that, HF still shows 3 seperate PN's on thier site.
So, currently there are three models available, and 60636 may be prohibited in strict smog areas.

I take it you do not have a Harbor Freight locally to insure you buy a hemi head?

Scout · Nov 13, 2013

Oh I do, I was there today to buy a big crescent wrench to swap radiator fans on my Dakota, and decided to look over the motors while I was at it.

Been watching videos on youtube, one guy took his flywheel off for painting and I see that the fan is just a plastic piece and the flywheel itself is flat, so that answers that.

And then, there is this video… http://www.youtube.com/watch?featur...dEGoJbQJf3M_Xw4TVAtb0HuMb&v=tfc_hAzf5ow#t=271 I love the way this engine sounds and runs. I'll be watching more of his videos to see what exactly he put into it, both parts-wise and money-wise.

That's the same design as the original Honda. The pics below show 2 genuine honda flywheels

danssoslow · Nov 14, 2013

Yeah, I don't think there is any inherent problems with the plastic blades. Someone has them available with every other blade cut off. I don't think that would be safe with cast-in blades.

OzFab · Nov 14, 2013

I cut about 1/4" off every blade (they were hitting a bolt or something) then painted it & the flywheel silver; looks awesome...

I'm collecting Predator 212 info and sticking it in this thread. Seems a lot of people use this motor, but there doesn't seem to be a lot of info on it here. After I get "enough" info, I'll make a new post that can be stickeyed if wanted.

Just some info on the Harbor Freight 212cc Predator engines...There are a couple "versions" on the market. First the originals, then they (China) made some "Hemi" style, (plug in center of valve cover), then pre-June 2013 with their original crank/cam, and now they have gone to a Honda spec. crank.
