Some questions

[Stock 400 rider]

1-I just got a new performance filter from K&N. I just have to install it and leave it this way or I have to lubrificate it with some oil or oil filter?

2-What do u mean by a flipped wheel?

The K&N if it was brand new it already has the oil on it. But when you clean it make sure that you oil it again (I am sure that you knew this though) ;)

The flipped wheel not for sure but are you talking about taking the front rims and drilling a new hole for the valve core and basically turning it around and running what use to be the outside of the rim on the inside. It will widen the front end.. :eek:
This will increase bumpsteer. :rolleyes:

thanks for reply
i don't think this is possible and worth the work for it

I like the stock set up better, flipped wheels(offset) makes thefront end feel real loose.
