I only recently brought my TTR on a private sale, good clean bike but, it would only run on choke but the engine sounded ok so I brought it. I found it was so clean due to over pressure washing water and some sort of cleaner had got into the carb via the air box. I stripped and cleaned out the carb, drained clea...

I have a 2003 TTR 250 which seems to have an oil leak either from the "o" ring on the starter motor or somewhere close by. There also seems to have oil seeping out the grommet with 4 wires coming out of it, just in front of the front chain sprocket. Thank you Terry.
