Here in West Seattle GS500 Club, we have come to the consensus that the K&N as a stock replacement is a waste.
Considering the time and materials to clean and recondition the filter, it is just easier to drop in a new paper filter. In the long run, it is less time, effort and cost.
You have to buy the stuff to clean them. Let them dry. The re-oil them. Frankly, we found that to be too much work and expense.
We now keep a few stock OEM filters on the shelf at all times. Take one out - drop one in. So simple.
At one time we though it was cool - a filter that lasts forever.... until we found the work involved to maintain one. For stock bikes, not worth it.
What was your reason for getting one?
Just thought it was a good filter
Hey hyper,
I had a stock 2004 and dropped in the k&n and noticed the same dead spot when opening her up on the freeway. So I took out the air restrictor and she ran great, albeit a bit lean, and she would overheat at full throttle in the hot days of summer.
So I rejected (see my signature for jet sizes) and the bike now runs great again without overheating. I dropped in the k&n mainly as an excuse to rejet, although honestly it runs just as good with a stock paper filter and stock jets.
Thanks for the info smoke. Do you have any recommendations for jet sizes on a 2009 gs500f
I referred to the rejetting matrix at http://wiki.gstwins.com/index.php?n=Upgrades.Rejetting
For your 2009, you can try the settings for 2001+, Stock Exhaust, K&N Dropin. Be advised that it is somewhat of a trial and error, so you may need to play around with different jetting sizes
