Appreciate the comment. That is my bike. My son married a photographer last year and they did a photo shoot of my bikes last October. My KO is a 1-70 build. I really like the candy blue /green most of all.
Roger that! I'm about to paint my K2 in that color, 'cuz it was what I always wanted, and couldn't get.
I hear ya' regarding the KO carbs. They do come off pretty easy one once you been in there a few times. Took me a bit to dial them in. In fact, I got so frustrated at one time I was going to remove them and put on a set of K1 carbs. Just could not bring myself to do it. Had to keep it stock and glad I did.
I've now received 3 sets of K0 carbs in the last year for rebuilds (1 from a sandcast), and 2 of them had 130 jets in them (!). That's mighty rich. Honda used 120 with the needle clips in the middle position, these have the 130 with the needles lifted ANOTHER notch. In all the years I worked on them, never saw so many over-jetted K0 sets before (?). Most of the time, we were installing 115 jets to try to reduce the plug fouling problems, or lowering the needles to the 2nd notch, and drilled the emulsifiers out to as much as .044" to let them get "blown out" on the freeway on-ramps a little easier.
One of the things that really aggravated the airbox deterioration was: the boxes were made from styrene plastic-based material, the inside of which was sprayed with a matte 'sealer' of some kind. The spitback from the carbs, once the plugs started fouling, would wet the intake tracts all the way into the box, wetting the paper in the air filter sometimes. The strong fumes then dissolved this matte finish, leaving a soft, powdery material on the surface that would wipe off with your fingers, and it collected on the air filters and clogged them. After that, the inner surface would start etching and then crack, usually starting between the velocity stacks of the 2 inner cylinders.
