Hello everyone, I have a strange problem. The bike in question is a '13 NC700XA. In the autumn I had starting problems, engine moved a little but the starter couldn't produce enough speed to start the bike. I thought maybe a bad battery, so bought a new one (old battery was a little weak). The season came to an end, but after installing the new battery a few times I still felt like starting the bike is a little difficult as if like the starter motor turns the engine a little slower than usual. Now today a friend of mine came to check out my bike as he wants to buy something like that, and I failed to start the bike (oh the shame). The new battery was on trickle charger, so one would think it's OK, but it acted as a dead battery. All it did was to turn the engine a little, but I felt it couldn't get through the compression (so it didn' really make a full turn.), the display blank while I pushed the starter button, it came back to life after, headlight looks OK, fuel pump sound normal (not with as a dead battery) I tried a new car battery also and the starter couldn't turn over the engine with that either. Moves a little but stops and after I release the starter switch I hear the engine moving back as if compression pushes it back. I attempted several times but I only to managed to get a few turns, but not near enough speed to start the engine. (The battery starts a car.) After that I tried to touch the jump cables directly to the starter motor cables to eliminate the starter relay from the equation, the result was the same as before. Now I removed the starter motor to check if there was something at fault there, but couldn't find anything obvious, I made the basic measurements, bearings, brushes look OK.
All in all I feel as if the starter motor is weak or the engine is hard to turn, I cannot really say it differently. I'll put the starter motor back tomorrow. Any ideas, what might be the problem? Thanks in advance for any input.
