Rat Rod Carb
First off, please let me apologize for starting a new thread on what has been (probably) beaten to death in the past. My Forum/Google-Fu isn't what it used to be, although I found some good info, but want to make sure I got this correct.
My 2005 1200C Sporty, Rat Rod, is running rich and getting 35 mpg at a steady 55 mph, which seems a tad low to me. I do not ever need to use the enricher, just hit the accelerator pump a couple times and it's good, with a tad low idle when cold, but I don't let it sit long anyway before taking off. It has a K&N little round air cleaner set up, and basically straight pipes. When looking up in the Screaming Eagle II 'mufflers', I see a little metal tab that really is only stopping a cop's night stick like they used to check for baffles eons ago. Sounds excellent, btw. At low throttle position like cruising in town at low speed and low rpm you can tell the fuel mixture is wrong and almost sounds like a V8 running on 6, but there is no surging or anything like that. All the way off the throttle or normal cruising on the hwy there is no sputtering or backfire. WOT it pulls hard, very hard. When turning in the EZ mixture screw, that the PO installed and I'm glad I didn't have to do it, nothing happens. Even all the way seated. I took the carb off to check the jets and found a 46 pilot and a 190 main. Also the only thing on the EZ screw is a spring and no ball I read about, but that might be just for the stock mixture screw.
From what I have gathered the pilot jet is too big and the main is probably OK the way it is. I read that the stock pilot is a 42 and that I should try a 44 or even a 45, if I can find one. I will buy new plugs and do the old school test of running on the low speed circuit only for a couple miles and then pull the plugs to see what they tell me, and then adjust accordingly. Does that about sum it up? BTW, the dealer here does not sell jets anymore. They will take your scooter in as a trade in when you ride it there looking for jets though. I now have a new 2019 Iron 1200 in Twisted Cherry. That thing is sweet. Yes, I'm a drug addict if motorcycles are drugs haha. I'm not in a hurry to get this carb job done, as I have painting to do on that bike in the meantime, but I want to get all the good info I can from people who know what they are doing. I'm no stranger to wrenching but I am on a bike carb. I thank you all in advance for your help. Here is a pic of the new ride:

Jesus. That's how I roll.
