Knowing what I know now, I'd still buy my bike again. It's sorta like a wife. I wouldn't take a million dollars for the one I've got, BUT, I wouldn't give a dime for another one just like her.
I love my bike. As much as we gave for them sure, we shouldn't be having to go through this. But, on the other hand, as much as we gave for them, what's a few more bucks to fix it right? Half of the people who have perfectly good running machines, spend 4-5 K to increase power anyways. Everytime I get on my bike, I'm amazed at how much fun it is to ride. Do it again? Damn skippy.
Oh, I love my wife too. Marry her again? Damn skippy. She's the one who talked me into buying the bike.
