Air puff from right side of blast?

[FilledWithChill]

I test drove a 2002 Buell Blast yesterday with 2700 miles. I am thinking about getting it. When I started it, it started up only when I pulled on the throttle a little bit, then it would run perfectly. Then i test drove it and it ran just fine with no performance issues and i had a lot of fun, but I noticed that on my right leg I would feel a puff of air everytime the cylinder moved up and down. Is this the carburetor backfiring? Or am I ok to buy this bike

Probably loose or cracked boots. Get a flash light and check it out really good. Probably an easy fix. I really enjoyed my blast. It was more comfy then most bikes I've had. What kind of price is on it? Should be less then 1500$$.

You should not have to give it any throttle to start it, that's the first flag.
The carb cough (second flag) is cause by a lean condition, likely the boot as arikam mentioned.
