I have a quick question about air cleaners...I own a 08 nightster that has stage 1 with vance & hines short shots and a screamin eagle air cleaner. It was dynoed a few months ago at the dealership and I want to swapp my plain jane screamin eagle air cleaner they instulled on it with the screamin eagle heavy breather....question..Should or do I have to get my bike re- dynoed after I install the heavy breather?
Thanks for all and any info!!

 

Drive it for a bit after you do the swap and see how she is running. Pull the plugs and see how they look also....then go from there

TIP: Make sure the plugs are clean first.
