Yes, its Spring time! Looking at those ads, I feel its my duty to clarify a few things.

Austin- Great looking bike! Some up close pics would be nice. Great price. The CB-1 engine is from the "CB"400RR and not the "CBR"400RR.
Jacksonville- The Spec sheet link is for non-US market CB-1s. The US bikes only came in smurf blue. Also, the US market CB-1s were detuned to 45 bhp. $3800 is steep. Thats only a few hundred less than what they sold for brand new back in 1989, with zero miles and no stickers on the tail section...
Vancouver- The red tank stickers were on the 1990 US models. The grey tank stickers were on the 1989 US models. This bike also has a centerstand, which were only sold on the '89 models and not the '90s, so at some point it was added or thats a different gas tank.
Tacoma- Looks very clean from the picture listed. If its that clean up close, and does not have many miles on it, its worth the 3195 asking price...
Just my 2 cents...
