I have a 06 Fxst and put a set of V&H Big shots Staggered on. I changed out the stock jet which was a #45, and replaced it with a #46. When I went on a test ride after that it would seem to want to cut out or stumble at low rpms. If i was running 35 mph in 4th gear it would cut out. After that i put the stock jet back in and problem went away. Any suggestions as what to do, or just leave the stock jet in. Thanks

 

sounds like leave the stock jet in.............what type of carb you running.........did you run a stage1 kit or stock?

 

Sounds rich.Leave the stock jet in.Get some new plugs and check them out on your own.You can go to nightrider.com and there is instructions on tuning your carb.It's a good performance site.
