Most tuners strive for around 13.2 AFR
Remember years ago when you would see bikes all the time like that. Heat shields are so nice to have.
Nightmare scenario:
I had a lemon of an '02 sporty that I bought brand new and within 3 months the pipes had blued that much...including the heat shield. Chandler HD couldn't get the bike to run right no matter what they did. Had it towed 6 times in the first 6 months after buying it new. Total desaster. Day it was stolen was a dream come true.
Thank goodness for the thief in Arizona when you have bought yourself a lemon considering that Arizona does not have a lemon law... 
Exactly. Insurance gave me back more than what I paid for it new and then they recovered it during a bust of a meth house. After the guy went to prison he had to work to pay my deductable.

I even had the opportunity to buy it back on auction....sold for $400

The auction place was over toward the Jeep Graveyard (apache dr in PHX, I think)
If I still lived there I'd be checking out their auctions constantly. I saw a CBR900 go for $25 bucks there once. Unfortunately I didn't have a garage at the time or I would have been bidding on that sucker.
