I just replaced all the bolts on my '96 savage engine, replaced the cam chain and adjusted the valves, replaced the brake pads, replaced the gaskets on everything I opened up. Checked the clutch plates but decided they looked fine and put them back...
When reassembling the bike, I quickly took out the old oil filter, put a new one in, correctly, and then realized I had a spare small o-ring and took the oil filter back out and replaced the small o-ring and thought to myself, what a silly thing, that old o-ring was just fine... then quickly forgot all about it as I reattached the oil filter cover with the 3 new stainless steel allen wrench bolts.
Next day, after letting the gasket material in the header to slip on 'cure' for 24 hours, I'm all ready to listen to the motor start up and see if I got the cam-chain in the right spot or if I missed by a link or two and would have to start over.
Turn the key, engine spurts - kicks in, spews some black smoke from pouring oil over the valves after resetting them, and I think, oh yeah, the chain is right and the bike is purring... I'll rev it a little, when suddenly...
POW!
And Oil is spewing straight out of the side of the bike about three feet laterally, like a jugular has been slit. I jump and turn off the bike and look down, the oil cover is cracked in a 3 inch half moon shape under the bottom half of the oil filter circle. I remove the 3 bolts and find that I put the oil filter on BACKWARDS! Covering the hole with the solid end!
Dear God, someone please shoot me!
24 hours later with a quarter cup of JB Weld soaked into the crack and waiting for a RonAyers purchase to arrive, the bike is running again, but man or man, what an idiot I am
