Rejet for a K&N?
Hello there,
my husband and I each have yamahas and are wondering if we need to rejet them to add a new K&N. Well he wants to know I have no idea what he is talking about Im just the typer haha [img]i/expressions/face-icon-small-smile.gif[/img] I have a yamaha 05 bruin and he has a 06 big bear.
Thanks for the imput
Also the values on his 06 400 4x4 Big bear need to be ajusted, Is that the same procedure as doing them on a 05 350 bruin?
Thanks much from California

It depends on how spot-on your jetting is now. On a machine that is jetted spot-on you can add just a filter and still be safe, but quads usually come from the factory jetted lean (to pass emissions requirements). If it's already lean you should bump up the jetting a little to be safe. You can tell how your jetting is now by looking at the ceramic tip part of the spark plug. If it's brown or tan you should be fine with the filter, but if it's already a real light tan or white color you'll need to rejet it.

I pulled the plugas out of my banshee the other day and they were covered in oil. Is my oil/fuel ratio a little too rich? Sorry if this is off topic. I will be putting a k&n on it in the near future....
