Yea, they contacted me to test and review their engine kit.
Long story but I let them talk me into it for a reduced cost ;-}
It is a centrifugal automatic clutch in a small oil bath, no lever, but no pedal start hence why 2 starting systems.
That's a super double bonus man!
Why in the world would you want to defeat it and add a manual clutch lever to your handlebars?
I love automatic clutches and this was a breeze to operate.
Mount bike, push start button, turn throttle to go.
Don't get me wrong, I like the engine, and you can feel that 4cc larger size, much like difference between an HS 142 49cc 4-stroke and a HS 144 53cc engine.
And it has dual front and rear engine mounts to keep it in place.
Darn nice system, smooth power and easy to operate if you can start the thing.
If they fix the starter issues this will make a fine 2-stroke with on-board 12V.
Best I've seen anyway.
Of course the easiest way to get 12V is by starting with an e-bike like this 48V ~1KW trike I'm building now...
But it's not 'self sustaining' power, you have to charge the 48V, but taping that is easy with a DC-DC converter to lower some working voltage to 12V and like 30A or something, suffice it to say more than you'll ever draw unless you literally want to light your bike up like a Christmas display ;-}
