When I bought my Kymco grand-ding 50 I already noticed on the way home that the scooter became weaker and weaker and partly only 30 before what is from now on always the case. The nice Mr. salesman said it was because he changed the spark plug because the exhaust so smokes I do not know the connection between hen spark plug and exhaust but I don’t think there is any well bought new spark plug and problem was not there then completely new clutch bought with converter problem is still there new Vario weights also replaced still problems I am with my Latin at the end. It could of course also be the carburetor that will not explain the quite loud hissing or clapping out of the vario box Here I uploaded a short video because I somehow on this page can not upload the error message is shown to me only half so I can not see why it does not workLink removed, please upload to a reputable provider. A provider in which you first catch 15 different types of nerve notifications etc. are not serious and also do not help with the error diagnosis. Dynamix MT-Moderation
