Old Car and Bike rambling

I had to pull the OEM carbs becase she was behaving like I had an air leak.  Under acceleration it was slow slow slow and then when the RPM finally hit 7krpm, she would start to accelerate hard. I had to pull everything out to check for leaks and I did find a few holes in the airbox which I plugged up. I also found a few of the slides on the OEM carbs a tad sticky due to small burrs that I sanded out of the slide shaft/body.  Hopefully these few items and better sealing carb insulators will resolve any issues next time the OEM carbs go back on. I had also wanted to try out a modification to the gixxer carbs that I read about which should help me with my rich idle problem.  Basically I had to drill out the pilot airjet 1 size larger (based on my harbor freight drill bit set) at the pod side of the carb intake to allow a little more air in.  It definitely has affected the carb's state of tune because I'm running too lean now even at 3.5 turns out There is a flat spot
