Tuning Assistance

Hello all.

I own an 05 Softail with the TC88B motor. It has received a set of Screamin Eagle II slip on mufflers and an S&S air cleaner assembly. The carb was completely rebuilt with one of Ken's kits including the accelerator pump upgrade and the velocity stack. After a whole lot of reading, I settled on the 46 slow jet and the 190 main jet.

My question is, how do you tune the slow needle? I have loads of tuning experience with both 2-stroke and 4-stroke outdoor power equipment engines but my Harley really baffles me. Per the direction, I keep my ears open for a stumble when I am leaning out the EZ Adjust but I do not perceive a change until the engine dies from an over lean fuel condition. Typically with small engines I always listen for an increase in RPM as I lean the mixture and a decrease in RPM when I enrichen it but I cannot do that with this engine? Any ideas folks?

You were right all along hotroadking! After reading your reply and after a little head scratching, I went back into the carb (I am getting really good at this now) and determined that I had incorrectly installed a #48 jet instead of a #46. I swapped out the #48 for a #46 which should solve the problem. I have no idea why I installed the #48 in the first place but there it was! Thank you so much for your suggestion.
