Nice torque curve but heavy and a limited rev range.
Interesting new YouTube video i just seen

They're simple to work with too, all the way down to the carburetors.

I did mean heavy and I did mean a small rev range.
Depends on the engine but most idle around 1800 rpm and top out at 3600 rpm. Some a little higher, some a little lower. Need at least 8:1 to use it on a 26 inch rear wheel, but 10-12:1 works better and assuming a centrifugal clutch locking in at 2000rpm is used you get 115- 175 useful rpm range out of your rear wheel, depending on gearing.
Limited rpm range to say the least, a honda trail 125 tops out at 7500 rpm and engages around 2000.
Heavy too! An 8hp predator is 60lbs dry, with no drive train, no exhaust. Apples for apples the ct125 engine is about 45lbs dry, no exhaust, no sprockets or chain.

They are heavy and rather under powered, but that's part of what makes them unique. I want to build my 3hp flathead to 10000+ rpm, but I'm having trouble finding a billet con rod. It's gonna be expensive to have one made too. Maybe I could go for less rpm range and just find (or make) an alternative to the oil dipper that always busts off the over 5000 rpm. It may not be the most practical or cost effective build, but it's something I have my heart set on and don't care what it will cost. Admit it, it would be wicked seeing a bike with a high out put 3hp flathead on it.

I think the YouTuber has a speech impediment… I can understand a South African eating a bag of marbles more clearly.
