Above is my current setup, basically just installed everything and used everybodies suggestions as a base line for my jetting. It was 25 degrees out today but the roads are finally nice so I decided to ride it. First off its fairly hard to start, turned choke on crank and it starts but dies right away. Had to do that a couple times for it to stay running, is this temp related?. I noticed if I leave the choke on for more than a minute I get a pinging noise from the carbs. Didn't here it any other time though. The top end is awesome and pulls very well and sounds good. However when downshifting to a stop my idle seemed to drop and when riding at around 4k it feels dead and the exhaust sounds really rough/choppy. Any advice on what to do from here, I think I need to start by backing my mixture screws out a 1/4 turn?
