ABSOLUTLEY NOTHING! crappity smack YEAH!
I do this kind of thing all the time! One of my favoties is in the morning, having a smoke, staring at he bike. And I think, "darn, my bike looks
good."
On the other hand, I have done mods I DO NOT LIKE aesteically... but I like comfort wise... specifically springs under my seat. Guess I'll have to take them off... it's a chopper!
Anyway, I think this is my favorite pic of my bike:

Now, compare it to this pic:

See how the "seat?" doesn't look as smooth and in tune w/ the rest of the bike?
Anyway, myh point is that I like looking at my bike. I like looking at my other bike, which is more or less stock. I like looking at
MY bikes. And it makes me smile when other people like looking/staring at
their bikes.
Now, Franch, you had better post a pic of your bike in this thread. Or else! Georgeakthe & Thumperclone are already worried I'm coming for a visit! You don't want one too!
