bikespace Posted January 25, 2004 Report Share Posted January 25, 2004 Probably loads of things that it could be. I'll leave them to the guru's, but is the fluid level OK and is it the right mix (I think GasGas used to recommend a VW coolant mixed 50/50 with water) More importantly - is the fan spinning well. I had one go gradually which meant overheating got gradually worse and worse. I put a 2003 fan on my 2002 because they were better sealed so it may well be OK. I'd forgotten how strong the fan used to be, but when I replaced it I realised that it used to cause a real draught. If you need to test it you can disconnect it and put a car battery to it. It should go like stink. See if there is any play on the bearings. A couple of ideas anyway Quote Link to comment Share on other sites More sharing options...
askie Posted January 25, 2004 Author Report Share Posted January 25, 2004 the fan cuts in almost straight away is this normal ? the coolant is good and fan works great more ideas ? Quote Link to comment Share on other sites More sharing options...
charliechitlins Posted January 25, 2004 Report Share Posted January 25, 2004 Couls mean it's heating up too quickly. Check the sparkplug. White could mean an air leak. Bumpy deposits could mean coolant leak and a blown inner o-ring in the head. Check if your exhaust seems to smoke more than usual, and check if it smells like coolant.

superflytx270 Posted January 26, 2004 Report Share Posted January 26, 2004 Try a different thermostat to see if the original is faulty. I know that the shop i hang out at had a few problems with these on this particular bike. Quote Link to comment Share on other sites More sharing options...
