Hi, I'm new here and new to HD's. I'm really impressed with this forum and find nearly any question I come up with has been answered in other posts or the self help sections. However, there is SO much information I get distracted and wind up reading page after page of posts and before I know it i'm off on a totally different subject than what I started looking for. I can't post a picture of my ride 'till I post a few times so here goes and TIA for your patience. I bought this 2003 FXDX with 16,500 miles on it for several reasons, I wanted a motorcycle again after doing without for over a decade ( I rode BMW's for 30 years), I know the original buyer well and know he took as good of care as local dealers could or would provide (I'm highly skeptical about the dealers quality of work though), I thought it was a good deal and figured I could get my money back out of it if I decided I didn't like it (I like it a lot!). Early on, the first owner had a stage one mod done by the dealer, SE II baloney cut mufflers, SE (K&N?) air filter/intake, and what appears to be a SE Carb re-jet kit (I have the box with several different new DJ main jets). I got most of the original parts from the first buyer, stock mufflers and air cleaner, main jet and needle. I have read several posts, here and elsewhere, about carb mods and was curious as to what exactly I have installed. I have had an issue with the engine spitting back through the carb when slowing to take a turn and even had it stall a couple of times after warm up when coasting into a gas station at idle. I gathered by the posts I read this indicates a lean idle mixture and so tried adjusting the idle air mixture screw. I found it was about 2 1/2 turns out and did much better @ three turns out. Today I took the carb off to see just what was in it and found a #45 pilot jet and a DJ main jet #180. The needle appears to be stepped rather than a smooth taper and is adjustable with six slots for the horseshoe clip. It also has three washers on top of the clip. The clip is in the third slot up from the bottom. The slide vacuum hole has been drilled, a 1/8 drill bit is a loose fit. My first question is; If I continue to have coughing through the carb, should switching to a #46 pilot jet be in order? Is a #46 jet preferred regardless with this configuration? Does this setup sound reasonable? I have done the wide open throttle test and in third gear between 3000 and 4000 rpm there is no noticeable stumbling or surge when I back off a little (1/8 turn), this indicates the main jet setting is +/- good, no? Any thoughts, comments questions, answers or suggestions?
