Small gusset and chainguard tab is usually indicative of the early Viper and Pacer 500. It looks like it has alot of non-DB stuff on it too. Like the bars, they look like either real or copies of CW`s. The forks aren`t DB either. Maybe Akisu, hard to say. Are the pedals Sharkbites or VP?
Anyways, cool little bike, nice find :wink:
