I am looking at a 1999 WR400. A boy is trying to sell it to get an enduro bike(XR650, KLX650), It has a few problems, Fork seals leaking, RS radiator bent, water pump leaking, does not want to idle but runs fine once you give it gas, and missing left side number plate. It does not have any of the lights it now looks like a YZ. The Coast Enricher has been removed fro carb and I thinking this is whats causing the poor idle. What type of problems are common with this bike? He is asking $800 for the bike. Is the bike worth that. I am prepared to do some work on it but I don't want it to turn into a money pit. Any advice or help would be appreciated.
