Hello I was woundering if anybody knows whet it would take to build a kt 330 such as don smith rode

to be exact would be nice but Il settle for somethng close if possible

Thanks

There are a couple articles on the KT250 site

I think Bob Ginder sold the last of his big bore kits a few years ago.

IIRC the big bore kit sold by the Tryals Shoppe was a 310. I have some suspicion, since a spacer plate was needed under the cylinder, that they might have used a piston from a Suzuki RM370A (piston port) or something like that, but since I don't have one of those pistons falling readily to hand and foot I've never been able to check that. I found a piston from a watercraft that seemed a perfect match with the KT piston other than bore until I found a couple of ports in the piston skirt that appeared to not be in places that the KT ports would appreciate. But the skirt length, bore, deck height, etc all seemed right on.

When I look at how much flywheel a 325 Bultaco has compared to a KT250 it appears that even with an add-on weight a KT330 would be pretty light on the flywheel mass. I'd like to have more flywheel on it as a 250.

cheers,

Michael
