when i saw the engine it did look like a single cam, but the guy said that the single cam bottom end used a harmonic balancer to make it able to have the twin cam head. or some thing like that, i wasnt taking to much notice of that engine as i had other things to do but i just got thinking about how it would go in the 1200. but it definatly wasnt an sr16
the rockercover was like an sr one but it was skinnier
as i said, ill go back and get some more info
