I bought a 76 550 . . . for $175. And it seems to be a collection of different bikes (I spied some yamaha controls on the handle bar) I took pictures and will post them soon. I am pretty sure I want to restore it to a degree . . . and will take more pics and update on my progress. A quick question, how do I know if its an F or K? The '77-'78 models had the F/K in the VIN & this bike apparently doesn't. It does have a 4-1 set up, not sure if original though. It has a cafe' style handle bar . . . and looks like someone was in the middle of a dual disc conversion (a brake caliper on each fork) . . . keys are non-existant (can I give the dealer the # on the ignition switch & get new ones made ?) . . . so can't look at the tank. What were the differences between F & K beside mufflers ? Is there an online parts fiche for this ? Thanks . . .
