seems that the blata website is down, cant find any specs. someone wants to sell me this bike for 500$ i would like to know some of the specs and features of this bike (HP etc..)

I'm getting this blata 2.5 in a trade Saturday and i know to look for blata in the casting on the motor...what else should i look for? And the guy said it comes with some kind of co2 kit? Looks like a air filter with a tube running to a trigger to shoot co2 in...what exactly is that? What's it...
