So, this is it, the last thing to do on my build before the bike is up and running, and it is stumping me. I rebuilt the carbs when I rebuilt the top end of the engine, and thoroughly cleaned them and bench synced them at the time. I am running pod filters and a 4-1 exhaust, and when I first fired the bike, it needed no choke and was idling at about 4k RPM. I checked the idle screw, and it was barely touching the carb body, so it was not causing the high idle. The stock original Keihin carbs were jetted with 110 main and 40 slow. I ordered a selection of jets, and rejeted the bike 120 main and 42 slow to compensate for the pods and exhaust. The bike required the choke to fire, but with the choke all the way on it was idling at about 2k. As soon as I moved the choke lever down to the off position, it revved to 5k. Rejeting to larger jets, should have brought the idle down by equalizing the air fuel ratio, but seems to have made the situation worse, any information on getting this corrected would be helpful. I'm so close to being done, I just want to get over this last hurdle.
Thanks
Also, I know many people on here hate pod filters. Thats fine. That is the route I have chosen to go, and I understand it does mean that there are complications like this.
