Nightrain asked:

I bought a used Nightrain last month and I need some help. I want to know if my bike has a Stage 1 kit on it or not and I don't know how to tell. I am not even quite sure that I know what a Stage 1 Kit consists of.

If it helps my Nightrain can do 110 mph in 4th gear and 120 mph in 5th gear before the rev limiter kicks in but I don't want to push that any farther.

Our Answer

Thanks for the question and congratulations on the new Nightrain....they are great bikes and I have one myself.....so good on you.

As for your question, a Stage 1 upgrade for a Harley Davidson typically consists of three things, an exhaust upgrade, an air cleaner upgrade and either a rejet of the carb or a reflash of the PCM depending on the bike. So to check if you have a Stage 1 upgrade installed on your bike, these are what you look to find. The actual mile per hour ratings will not tell you anything.

So if your bike has pipes and a non-stock air cleaner or filter assembly (usually K&N) then you have already been upgraded to Stage 1. To get much more power out of the combination, you will need to go into the engine, which most are not willing to do.

If we can help...feel free to ask.
