I wasn't picking on you, just an observation from years in the field. I bought 
too many cars that turned into money pits and eventually got to the point where 
I had more in then it was worth. I don't wish that on anybody. When it comes to 
bikes, I'm a realist.

I always check my tires before I ride, just habit due to the guy who
put my tires 1st didn't replace the valve stems so they would go flat
in a heartbeat and now that they're fixed I have no problems.So I'm ok
there. As far as my upkeep on the bike, I baby it and try to do
everything that I know of to keep stuff from tearing up. Anything that
comes up, I either come here or go up to the local bike shop. Just
with a bike or other form of transportation that you buy in bad shape,
you do your best to get it running, drive/ride it, and then wait for
the surprises that come up. No my forks aren't leaking, just a
question, trying to gain lil bits of knowledge. Thank again for the
info and advice.
