    Does anyone have any info on it I got my heads off the bike and I’m thinking of going for it. Are there any other upgrades that will have to come with the big bore kit? New cams, valves? I know I will have to re jet my carbs and I plan on putting the Mac 4-1 exhaust on it.

    The big bore kits have had mixed reviews. One issue is that the cylinder liners are on the thin side and they can crack.
    A better choice is to source an XJ900 engine, or an entire running XJ900.
