know its a ford forums n all, but i'm after a 125cc or bigger (up to 250) for a backyard/dirt go kart. Not really looking for whole bike, unless a wreck as I'm only really after the engine. Dont really want anything flash (i.e. $$$) as its just gonna be a thrash around.

Cheers

best bet call up some motorcycle wreckers

250cc will be min
get air cooled!
best part is the engine will have a 6 speed sequential gearbox with it!
even a 20hp engine will make a kart f**k fly

yeah thats what im aiming for, called a bunch of wreckers in qld but every1 either has nothing or all reco'd gear for like $1k

i have a rover 187cc motor off a lawnmover just reconed make an offer
