OK, this post is more of a warning for some and perhaps a good chuckle for others. (The bike is a 05 CBR600rr)
I had a particularly stuburn oil filter during my oil change yesterday. I tried a filter wrench and socket but ended up stripping the polly filter wrench. OK, time to switch to plan "B".... Grabbed a long screw driver and a hammer. A couple of enthuesiastic whacks with the hammer and I was able to punch through both sides of the filter and get the 1/8 turn in order to break it free. She spun off by hand the rest of the way. Put on a new filter, filled it up with oil, fired it up, and checked for leaks.
I was surpised to see I was leaking coolant. When standing at the front of the bike there was a cylindrical part a few inches to the right of the oil filter. In my furious whacking I punched through the oil filter and straight into that part and it was spraying coolant when the bike was running..
I didn't have a clue what the part was so I called Kelly, the parts manager, at Big Top Power Sports for help. He was able to help me identify the part as the Oil Cooler and source a replacement (he didn't have any on hand).
So, I have to pay a $120 stupidity tax (the price of a used oil cooler) and spend some time pulling my bike apart to install the replacement. I can't pick up the part till Tuesday so I will be caging for awhile.
Thanks to Kelly at Big Top for pointing me in the right direction.
For myself.... "Here's your sign".
