Well I had the dealer do the 600 mile service, just to be safe with warranty stuff. Changed the oil yesterday @3k myself. Tried the usual hand strength to get the factory filter off. 9/10 times I can do it. Not this time. Went to the trusty filter wrench.....nope. At this point I'm a little pissed. I do the poke-a-screw-driver thing to it, and start to twist. Nope...the screw driver just tears an oblong hole in the filter. I try vise grips and all they do is slip along the filter body. Now I'm really pissed, and beers are neccessary to calm down. I'm thinkin....what ass-f*$ck at the dealership put this thing on so tight? Then I think maybe they didn't change it at all. Anyway, I go back to the garage with a little buzz, and use a hammer and punch on the hole created by the screwdriver and wahhhlahhh!...it budged about 1/4 ". So I put the filter wrench on it and it still wouldn't move, and believe me I'm no weakling. I use the punch again and finally get the thing off. Went with the purolator long version and Amsoil. Also I didn't fill the oil up so FU&*ING high like they did at the dealer...just enough to go between the high/low lines. AND, casting aside the placebo effect, the bike does seem to have a little more pep and it runs a little stronger and cooler, esp in this heat wave. Anyway, I'm kinda suspicious if they ever changed my filter at the 600 mile service....I know that makes no sense but I can't imagine any decent mechanic putting that thing on so tight. I've heard of them being on tight from the factory though.
