CB750K Cafe Racer

I researched what size jets I should be running with POD filters and a 4into1 exhaust.  I came across a great channel on YouTube called TheMotorcycleMD .  He specializes in vintage Hondas and has an awesome array of service videos.  In one of them he addresses how to tune the carbs when running POD filters and happens to mention the jets and setup for carburetors on a 1981 CB750K (thats what I have!).  You only need to open up the primary and secondary main jets.  The primary goes from stock 68 to 80 and the secondary goes from stock 102 to 116 (the closest one I could find is 118).  I got these from Randakks as well.   Jumped into the totally-not-panic-inducing carburetor rebuild.  I separated the bodies and disassembled each carb, making sure to cleanly organize each one.  I broke them down until every metal piece was free of any rubber/o-ring.  One carb at a time I dipped all the metal components into a carb cleaning dip for about 2 hours each.  I scrubbed the outside surfaces a

Finally got around to finishing up the engine.  Used a feeler gauge to measure the gap between the cams and the shims.  Ordered a valve shim tool to push the buckets down.  Used my wife's tweezers to pick out the shims.  Measured them with some calipers to compare them to the spec, which is .06 - .13mm.  You annoyingly have to put them all back in to keep measuring them so the cams dont damage the buckets.  Putting them back is NOT as casual and fun as the online videos make it look... The shims are a pretty tight fit so they kept sliding past the buckets instead of seating.  There was only 1 out of 16 shims that was barely in spec, but none of them were shockingly out of spec  indicating something scary, just normal wear for a 40 yr old engine. I went ahead replaced all 16 shims to land mid spec around .09mm.  To calculate each shim size you subtract your desired gap (.09mm) from your measured gap, add that to the measured shim and then round to the nearest .005mm.  After puttin
