on fleabay, no buyers, then its hacksaw time, Cant miss it, search for NSR250 its number 122, has a problem with top cyclnder, running rich according to plug chop, not alot of burn happening compared to the other one.
ie more smoke from bottom cylnder exhaust than the top one, this could be a carb problem as ive checked the HT lead and its fine. But you boys should know how to fix it, selling as i need funds to buy my 21 bits from tyga!!!

If i do end up choping it, make a list of any bits you need, its a race bike so dont expect road going bits like switch gear, lights etc etc
