I like the K&N just fine. Easy to service and it doesn't need servicing very often. Oh, and if you (anyone) thinks a Valkyrie gas tank is hard to remove, you haven't done it enough times. It's an easy tank to remove, two bolts and a couple hoses. There is that additional step for the IS to unplug the wire to the sender but that's easy too.
A lot of us also have to take the chrome frob apart for
the petcock, and then later get it all back lined up and
back on there like we like it.
I don't have particularly big hands, I can reach all the
needed places and hoses, and I know about lifting the
rear of the tank and holding it up with something to make
it easier to fish around up in there...
I've set the tank down on its nose twice now and had gas start
to siphon out the vent pipe like a fountain.
Since my hands aren't too big and if the tank is not too
full, and if I don't burn the pole barn down, I agree with
Jeff, it's pretty easy...
