January 31, 201115 yr Hi All, I'm scouring the internet for bike classifieds and have come across a Gas Gas 250 on Ebay which fits the bill. The owner seems to have advertised honestly, which is a good thing, but now I need to understand the faults he's described. He states that the previous owner told him the carb was recently rebuilt, but that he has found it hard to re-start if you stop once its warm. He goes on to say if you switch the fuel off when you stop and back on when you start then its ok. all mentiones that the fan is now hard wired and runs all the time. Does this sound like a problem or not? If not, the moneys right so I could be jumping in a van for a 400 mile round trip! Look forward to any responses. Dave.
January 31, 201115 yr Sounds like the float isn't set correctly. A lot of riders do set the fan to run constantly but even so a Thermostat is not a large amount of cash. Depends on the year as to fitting though. The Tube framed bikes tend to have it in an accessible position. The earlier ones can be awkward. Edited January 31, 201115 yr by Telecat
January 31, 201115 yr Author Thanks for that. So... assuming the float isn't set correctly, that would mean the carb floods? I vaguely remember having a similar problem on an old MX bike and I seem to remember that a clean out sorted it. Worst case, replace the float pin in case its slightly bent, causing the float to stick? If thats the case, it doesn't sound too disastorous and probably wouldn't be enough to stop me getting involved!
