This is what really convinced me that K&N filters are the way to go:
You get increased airflow which has to lead to increased performance and gas mileage. I have a K and N air filter in my Harley, Subaru, Chevy RV and BMW. With gas north of the $4 mark here still in CA anything to get even a little more gas mileage helps.
Gas guzzling polluter!
I was thinking about this yesterday:
Sure I make more noise and carry less passengers. And there is no catalytic converter so the exhaust gases are not broken down the same way. Is there something else I am missing?
As defined by Wikipedia:
A compression release mechanism works to ease the starting of internal combustion engines by allowing them to spin up to starting speed without having to work against the pumping action of the pistons. It does this through a release valve that is incorporated within the cylinder head that vents the cylinder pressure to the outside atmosphere until the engine has sufficient momentum to overcome it. At that point the valve closes and the ignition is engaged.
Basically this lets your bike start easier. Be it by foot or by starter motor. This is especially important on high performance large displacement bikes like Big Dog and other S&S engine based custom bikes.
When yours goes bad here is the tool to replace the compression release valve
We sell Automatic compression release valves as well as the S&S compression release kit.
