While I’m NOT an authority I’d say this one looks very well sorted out with upgraded air filter, brakes, carb and no doubt ignition.
She runs like a scalded dog. Handles like she “planted” in the turn and if she was a singer that Kerker would be Pavarotti! Only downside is that I think I have a small head gasket leak from the high compression of the 650 head on the 750 juggs. No biggie really. I’m getting the hang of wrenching on this thing. Still a wee bit of jetting work to be done but it’s pretty close as is for a frankenbike with 900 carbs/pods/kerker.
