Starter R1 RN 12 defective?

Hello dear forum, I have been fighting with occasional starting problems of my R1 for some time now and hopefully have circled the error on the starter now. But I would like to have confirmed this by myself again roughly before I get one out of the bay! Not that it comes to something else afterwards…. I know that a remote diagnosis is always a bit difficult but I hope the one or the other can say something about it…. The following error picture appears occasionally…… Try to start the R1 – it either blows through as if the battery was empty (at first at creep current but the battery is fully charged) you can then press the start button several times until only the relay claps and the yellow light lights up in the display or – There is no turning of the starter and only the yellow lamp lights up in the display. or – In about 70% of the cases it starts quite normally as it should, that does not make it better of course…. Now I thought that it is the starter, possibly the free run of the clamps, so gear in, moped with inserted gear once shortly before and back, gear out again and see there the little jumps problemlessly. I therefore suspect the starter having a blow (possibly the free run??), now it is extremely uncool not to be able to rely on his moped, therefore I would like to replace the starter. Since I am not so 100% sure if I have circled the error correctly I hope you can h Is it possible that I can first expand the starter and test it?? So not only that it turns when I connect it to power but possibly also the free run… Thanks for your efforts and comes well into the season and above all comes home safely again and again!!!! Torben
