I have a standard DRZ400 S, '01 I bought it a couple of weeks ago and it was fine, but after a days trail riding (including a few 'offs') it has become really difficult to start. When turning the bike over from cold it just turns and turns, doesn't fire up. If I crank the throttle a little bit it sounds more like it wants to fire up, but then stops. This also runs the battery flat very quickly. I can start the bike pretty easily if I jump it from a bigger (car) battery (once started bike runs absolutely fine, and starts ok when warm too), so I thought a new battery would solve the problem - but no, still same problem with a brand new battery, I have also changed oil and spark plug, no change. I have trolled through the forums but am a bit confused by the sheer volume of info! does this sound like anything particular? I have tested the RR - seems OK, the stator seems good, although I not yet tested the output whilst running (the engine cut off when I unplugged the plug with 3 yellow wires - how else do I test it?) will the "free power" mod help? (I am going to do it anyway when I get the chance, but dont really think this is the cause of the prob) please someone tell me what I have done to my bike, I want to ride it!
