-have complete jet kit for this thing
and a bunch of other stuff I can't remember. I have over $1000 invested in this sucker (probably more but try not to keep track of this stuff
). It runs but needs some tuning to run correctly. Thought this could be the ultimate pit bike but I have other projects that are taking priority. I have the body work off of it right now, easily put back together. Looking for around $700 or best offer. If you are looking for a unique pit bike this would be it. 
Trades possibly considered.
