All stealerships will deny anyone makes a part that they don't sell, here in Dallas i was told KN does not make an oil filter for the 900, KN 303 works great have one on the bike now, and has a unique way to get the thing off, yes all KN products are pricey, was also told ROYAL PURPLE MAX CYCLE OIL will RUIN your clutch, YEA RIGHT, they don't sell it.My local kawai dealer told me that they dont make a NGK Iridium plug for my 07 vulcan 900 custom. Is this true or are they just not up to date. Ive only got 7000 miles but its the standard plug. Time to update the plug. Any advice on this thanks.
