Slow Jet Size

2003 Night Train with Short Shot Exhaust. Previous owner put exhaust on, Screamin Eagle Stage 1 kit, and changed Slow Jet to #48. I took it into my Harley Dealer this week for starting problems, and they changed the jet to a #45. Good or bad move?

I imagine when you say "starting problems" that it's symptom was "cranked but would not start"-otherwise they were a long way off from the starter! If it is running good, then all is well.

Go with at least a 46, 48 was probably right. Did the 45 fix the starting issue?

A #48 is the norm for a stage 1. I am wondering if they compensated the jet for actually another issue.....

Ok here was the problem. Bike started fine when I first got it out to ride. The problem happened after I would ride for awhile then stop for gas or a break. After the bike sat for 5 to 10 minutes it didn't want to start unless I turned the throttle a lot and pushed start at same time. I also checked the plugs and it was running really rich. They were solid black around the threads. I took it to Harley and told them what it was doing and they said that the carb was probably getting loaded cause of the #48 jet. So thats why they changed it to a #45. I guess they know what they are talking about. I am new to carbuerated bikes. Let me know what you guys think

Dyno jet kits usually come with a 48 slow, so most dealers are used to using it. The 46 is far more appropiate for a simple stage 1.

The PO of my bike had installed a dynojet kit and I was having the same problem. I rebuilt the carb, changed the slow jet to a #46 and the high speed to a #185 and installed a stock emulsion tube. No more problems and the fuel economy is alot better.
