Laverda engined kart

[mcnicol]

Saw this on subito.it, never seen a kart with a Laverda engine before (probably never will again ). 125 Lesmo donk, claims 36 bhp . Can you say "hand grenade"? Single ring piston, expansion chamber ... maybe plutonium fuel? Has a Dellorto, should be able to handle it, won't leak .
Incidentally, OK, when you put new pistons in a 4-stroke Laverda and run them in carefully, all the microscopic bits of metal that got knocked off in the running in process end up in the oil, and get trapped in the slingers, right? We all know this.
So, where does all that crap go in a 2 stroke motor? Out the exhaust port? How?

  All goes into the exhaust, that's why they make that ringy-ding noise, little end rollers bouncing around in the expansion chamber.

That's for kiddies, Ken.

A friend once built a shifter kart with a 250 Kawasaki 2 stroke cross engine, all 56hp of it.  Loads of fun!

most fun you can have on 4 wheels
recommend you try a 2-stroke 100cc class sprint kart before going to shifter karts

parilla made kart engines into the 80's and may still do so

quite a few of the best F1 pilots got started in karts
