Yamaha Majesty 125 no longer works

Hello everybody! my father-in-law in Spe just went out after a freeway ride. No loud noises, nothing special happens. Taken off, wanted to go on and he said goodbye. I offered him to take care of the problem, but unfortunately I can’t get any further. To the symptoms: the starter doesn’t turn. You hear a relay clack, sometimes you hear it turn around 5°, but nothing else. So it seems a bit blocked to s A. What I’ve done so far: Variomatics completely disassembled. So cover left off, clutch taken apart, behind the starter freewheel also removed and the motor turned by hand with the ratchet. Both with the whole mechanism from the clutch to the starter freewheel, as well as without the parts. Result: – Motor can be rotated by hand with tool, but for my feeling quite difficult. No difference whether the freewheel and the clutch are in it od it doesn’t. Since nothing else hangs on the shaft after taking apart, I assume that the engine blocks 🙁 – Starter turns as soon as I have the Vario outside and just the close of force between starter and engine falls away. So it’s obviously not on it. Does anyone else have any ideas/thoughts about what it might be, if not on the engine itself? I didn’t expand the flywheel on the opposite side, because I don’t think that behind it something blocki Or am I wrong with the assumption? It is still striking that the starter – already for years – spins every now and then. This means that he sometimes does not react for over a minute, until he can then be persuaded to fold. After that he always started as usual. Since he gave up the scooter during the ride, I guess there is no connection here, but I did not want to leave it unmentioned here. Next step would still be to remove the cylinder head and sha uen, whether there are bars or anything in the cylinder. Are there any tricks to save yourself, except to measure the compression during dudging? I am grateful for every tip! Think the father of my girlfriend would be very happy if the bowl is running again 🙂
