Hi Cynic, Thanks for the suggestion. I've checked the water system pretty thoroughly - The pump seems to be working fine, and the water is circulating. I've taken the rad off an cleaned/checked it - it was in v good condition. Do you guys think it could have anything to do with timing? I know overly advanced timing might cause overheating. As I mentioned I've tried a replacement CDI - so that's not the problem, but possibly some mechanical part of the timimg system? Thanks, Andus

Hi Guys, Thanks for your replies. I forgot to mention on the first post that I've checked the thermostat - which seems to be fine. I've even run the bike without the thermosat fitted and still have the same problem. Also it seems to me that the bike is definately getting too hot (regardless of the thermometer reading), so I don't think that's the problem either. Thanks for the suggestions though. Any ideas what the next most likely culprit would be? Thanks Andus

Hi, I have a DT125R 2002, which has been fine up until this summer, when it has started to overheat. Now, after about 5 mins riding (or 10 mins with the engine idleing) the temperature gaguge gets near the red mark. Things I have already checked/done: - Changed whole carb from another bike - Changed CDI from another bike - Checked water impeller - 2 stroke oil pump checked (and oil added to tank to double check) - Air filter checked. - Checked for leaks Still it is overheating. Does anyone have any suggestions of something I have missed, or perhaps something that is very likely, that I may need to check again. Thank you for your help, Andus
