If I add a K&N style air filter to my stock air cleaner/carb setup will I need a rejet?I have V&H pipes.....

 

yes....

 

thx,I will go back with a OEM filter then!!!

 

I doubt a rejet will be required. There is very little increase in airflow when you put a K&N in the stock can.

 

You wont need to re-jet with that set up. You also wont get much benefit from the K&N filter in the stock box. Save you money and get a more free flowing air cleaner, and then you will need to re-jet. But re-jetting isn't that difficult, or expensive.

 

+3..

 

+4...

Has it already been rejetted for the pipes? If so, it could still be OK with a better flowing a/c setup if it was jetted a little rich. No way you can do useful pipe and a/c mods without going larger from the stock jetting, though - it's already set up lean from the factory.

 

Not rejetted for pipes and dont want to do it.It runs good enough for me as is and I wont change it,Im just tired of buying a new OEM filter every year,so I want to get a K&N style so I can clean and reuse it.
