Could be something simple like a bad earth. Go to a bike shop and ask them to perform a battery test, should be free. or (sigh, (the crappy time option, sorry)) The bike has a multi stage alternator, which kicks in and out depending on how much power you need. I would ask someone to check this if its not your battery. Do you have trouble with anything else lowering the current when you use something else? Best of luck!

Thanks Rudi. If the bike was restricted would that affect the 0-60 as well as the top speed?

I have recently bought a Dt125 R 2001 2 stroke, which I am having trouble with. When I bought the bike it was in a pretty poor condition but the engine seemed to run ok. I have been running the bike daily and it had really poor acceleration and bottoms out at 55 mph I have checked the air filter, changed the oil, clutch plate and cable and also fitted the correct spark plug (as some fool was using the wrong one). Also changed the oil settings, as it was really drinking oil and checked the boost valve settings. The bike seems to run better and is quicker, but I still don't think its as quick as it should be and still bottoming out at less than 60mph A friend of mine seems to think that it might be oil in the exhaust system from poor oil settings and also it might need de-chocking but i have no idea how to do this? Any suggestions on what to use? The bike seems to do about 100 miles on a full tank? is this right? Also I have noticed, if I have the full beam on and I break I practically loose my main beam! Is this normal? I figure its the battery which needs replacing, Could the 2 issues be related? Any suggestions would be great! Am going out of my mind! lol
