Hi folks
I have a little Kawasaki MT1a mini bike from 1973. Great little thing, all road legal as it needs to be here in the UK.
A couple of years ago I pulled the original engine out as it was on its last oversize piston and decided to out it to one side so I didn't wear it out as parts are scarce, especially this side of the pond.
So instead I fitted a minarelli AM6 complete with radiator and stuff, pulled straight from an Aprilia rs50. Tuned it up as one does and have been riding it like that for the last 18 months.
Now here is what I want to do. I'd like to keep the AM6 as I have a couple of these but I want to lose the radiator. It is not in keeping with the bike at all and it restricts my turning circle as the forks clash with it.
So I'd like to remove the water-cooled cylinder and swap it for an aircooled one.
Anything is possible of course with a but of effort.
The standard cylinder stud spacing is 52mm x 52mm. And to add the reed assembly is in the case not on the cylinder itself. That rules out the AC minarelli vertical cylinder. The Horizontal minarelli is ok though but uses a 50mm x 50mm stud spacing. I could get around this however I thought I'd throw it out to the forum members and ask first.
Does anyone know of an aircooled cylinder that uses an 52mm square stud pattern? Piaggio maybe.......
