basically this guy is willing to swap my zip for his runner 125cc which has been converted from a 50 apparently, what do you guys think? http://cgi.ebay.co.uk/ws/eBayISAPI.dll?ViewItem&item=250589516804&ssPageName=ADME:X:RTQ:GB:1123
Dont buy a conversion mate. Even if its done well at some point something will go horribly wrong, the engine mounts are normally what go on a conversion because most people hack up a 50 mount and bang a 125 engine in it.. therefore it ends up snapping due to having over twice the power its designed to hold. Find yourself a nice one even if it costs alot atleast you know its a good bike.
