Searching For 150cc 2 Stroke

[directdrive]

I have been away from the forum for awhile but have been busy with projects. I'm looking forward to getting back to restoring the Emmick Lightning. Right now though ( and I know this is a little off topic ) I'm into these.https://www.youtube.com/watch?v=G6rzv2yljSM
Now that you've seen the video, even the most ardent kart guy has to like that.
So here lies the question. Where can I find a single cylinder 2 stroke engine in the 150cc range with an output shaft only for a reasonable price? Seeing as this is the "DIY" Go Kart forum that means KT100's, Parilla Leopard's ,and Rotax are ruled out as are Jetski and Snowmobile engines ( because you have to buy the whole thing)as they just cost way too much. I have scoured the Web looking for a stand alone single 2 stroke in the 150cc range and have come up empty. The ones used in Thailand come from 2 stroke rototillers apparently. Somebody on here knows where to source something. Again, I know this isn't Kart related but you have to appreciate it for what it is.Thanks.

I could recommend one of these, but it will never produce what is shown in video...even if heavily modified.

DIY does not mean you have to build every piece of your project . A kt-100 will run you about 200 to 250$ .with 15-20 hp id think that's more then enough to get you going .But to do thoughs speeds i would turn to something more of a snowmobile engine to produce more power .

Either Get The Lawnboy Duraforce 6.5 Hp Which When Modified Can Make Up To About 10hp When Modified, Or Get A Old Single Cylinder Rotax Which Can Be Found Very Cheap On EBay

Hey Russ. You know I have looked for the elusive Duraforce. I can't seem to find one. Maybe they were not as popular in western Canada. How many horses do they make?
As far as the KT100 goes they are a little cheaper than I thought (saw some on ebay) in that range. BTW, those 2 boats racing are full on 750cc 2cylinder Yamaha's that are modded right out. 100 mph pass! Also very dangerous. I would be satisfied with 10-15hp.
It's basically a surfboard with an engine strapped to the back and a 7 ft prop shaft.
I just thought I'd put it out there to see if there was a cheap alternative. $250 is completely do-able. Have any of you guys ever used a saw engine? I just finished a welded aluminum 16 1/2 footer that is going to have a GX440 ( Vegas Carts) with all the billet stuff.The little race boat will be just for kicks. Thanks guys.

How many horses do they make?

Unknown...
Originally rated 6.5hp @ 2900 RPM.
I can run them at over 6800 rpm while under load.
Compression ratio has been bumped up slightly along with a Tillotson carb which helps engine to breathe a little easier.
Brand new short blocks are available for a $100 on Ebay.
Only the largest of chainsaws may work and are unbelievably expensive and difficult to get a hold of.
Edit:
Stihl MS 880
or
US820 may be more inline with your needs.

The US820 only makes 8 hp and costs $600. The Vintage is $1000. You are right about saw engines, not a good option. Honestly a KT100 makes 15hp @10000 rpm seems like the best bang for the buck. They do run 4 stroke classes over there too, and I have two 6.5 clones and a GX160 in my shop,but the 2 smoker just sounds way cooler. Thanks.
