I've got an 03' 1300S that I have put some V&H bigshots on and rejetted with a dynajet kit using the 195 jet and the replacement spring. It was running a little lean. It was popping and backfiring slightly when cold and seemed like it took too long to warm up. As per recommendations I turned the mixture screw out about an 1/8th. Seemed to help a little so I just left it til another day. Today I took off the PAIR valve, took the reed valves out and used the same reed plate with the rubber gasket, replaced the reed covers with some Baron's block off plates. I then richened up the mixture one more 1/8th. It seems like it is running leaner now than before. If I pull the choke out a little it defenitely runs better. I stuck a screw in the vac hose. Checked all of my other hoses and don't think I have any vacuum lines off. I'm perplexed! Any suggestions?
