Gidday Guys,

Ive got an MC21 that has had big end bearing seize/disintegrate with the resulting mess hurting bores/pistons/crank bearings etc

I have found a replacement MC28 engine which, I think, will be cheaper to put in than repair the one I have.

Before I buy it, could anyone please tell me if its just a straight forward swap, or have I got some work to do with different electrical connectors/carb rubbers/powervalve connections etc?

Any advice or comments would be appreciated.

Thanks very much

its a straight swap as far as i know but the flywheel has less advance than the 21 flywheel but you can change that over from your old engine i think there are some other small differences but not to sure on what they are

You will also need to swap the gear postion sensors over and the inlet manifolds.
