Hello community, first of all a little history. I own a 50cc Peugeot Vivacity Bj. 2001 which was once officially admitted to 70km/h. I had it throttled in a workshop (invoice “Drosselung im Riemenstrieb”, because I didn’t have an A-guide at that time. That’s fortunately different now and after a short phone call with a Dekra employee it was said that I could come with all the documents and he would look at it. So today I wanted the Distan So far so good, box on, fan wheel off, sleeve down. Strangely, however, it seemed to me that there was no distance between Vario and fan wheel anymore, and the belt was practically clamped in between, if I had bolted everything together again for a try. I suspect that the throttle was caused by the replacement of a longer sliding sleeve, not by the insertion of an additional one. With the photos. (1st picture after removal of the fan wheel, 2nd picture after removal). , 3rd picture after distance from Vario, 4th picture Vario and V-belt without distance ring/glide sleeve, 5th picture length of sleeve=4,8cm, I think it should be quite exactly 4,4cm long) Can you confirm my guess? I am still in contact with the workshop, if I can get the original parts back. If not, can I buy something like this iwo? (link?) Thank you!
