Sorry, Should have been more specific. I was talkin 2 stroke. Sled engines to take it even further.

A completely different animal than a 4 stroke twin. A 4 stroke can make power at an rpm that is good for longevity. A two stroke will need to spin (on average) about twice as high. If your HD had to do business at 8g's all day it wouldn't like it either.

Mine was done at 5800 rpm, just a waste after that.

I dunno, my buddy has a 900 ZR big bore cat and no troubles, a twin it makes 150hp bone stock. Drives like a grandma sled until you hit it. Then it makes 60mph in 2-3 seconds it was hard to tell. He has a couple hundred spikes and carbides, otherwise bone stock. Has EFI on it, it would be a brutal cart engine for sure. Little brother to a Thundercat I suppose. They tell me the triples are too heavy, the twin will make the same power now and smaller/lighter.

The sled 4 strokes are just a rebuilt ricer engine, most appear to need a turbo to keep up with the 2 strokes....nothing out of the ordinary there. Read about a guy saying his sled was so fast, yeah, he was running 25+lb of boost or something crazy like that. Good thing it never gets warm weather on a sled. I had turbo cars that would retard in 90F heat on 94 octane, yet I could run full boost/timing on regular when it was 20F out lol. Actually more than stock boost and timing on that car, you always run water wetter in those.

Good luck with what ever you end up doing.

Yeah I think a 700 motor would be very ideal, but a 500 might be plenty still. I don't want top-end speed like over 60 MPH, so I'd probably do something like limit the throttle linkage travel or something. I'm keeping my eyes open for a good deal right now. Saw a 2001 Sportsman 500 that had a bad rear diff and they only wanted $500 for it, but it's in Baton Rouge... way too far of a drive for me lol.

I've been meaning to ask is your cart a factory Limo or has it been stretched by someone.
If it's a factory cart it's a G-20 I would think, mines an 01 factory and it is. Just thought I'd ask.
Yeah you know Lurch, I'm still not too clear. The tags I've found on the cart say "JN6", which according to a dealer pamphlet I have that means it's a G16. Not really sure though. It seems to be a factory limo though. Has OEM longer brake cables, throttle and carb cable, etc. How can I tell for sure?

Big bore 2 stroke twins fly but they won't last as long as a small bore. Harmonics is a problem. Many have balancer shafts to compensate. Problem is balancer shafts don't eliminate vibration. They just move it to a different plane. They help but.... 800 and up seem to have the most problems. Some are better than others. I have one customer with a Cat 1000. 2500 miles. 2 engines. He's dumping it for a 4 stroke Yammie.

The only ricer based CVT 4 strokes are made by Yamaha. They have 3 and two have their roots in bikes. 1000cc 4 cylinder and a 500cc twin. The third is a 1000cc tripple. It was built from the ground up to spin a CVT clutch. All three are outstanding powerplants and don't need boost to keep up. Guys are putting them in everything from sand rails to helicopters. Boost one and they are untouchable. The 1000 will make 200 relaible hp on pump gas,, easy. The 500 will do 140 boosted.

Here's a vid of the Yamaha 1000 4 cylinder in mod form at the grass drags. 500 ft, 3.89 seconds, 132+mph.


Factory boosted CVT engines are by Cat, Doo and others. They are more of an industrial type engine and need boost to compete. They run good too.

Ha, yes it is man was that a fun car. Engine had a heart of gold. What was it 74mph in second gear at 7K rpm? Cars are faster now but back then they were pretty hot. Never forget the sound of those intake valves dropping open at 4K, then you were on your way.

Oh they run them, but that sled is for dragging not really for riding.
