Here are the Pics...
It's sesaon end here in northern germany and so i clean the Bike. And as i clean the downframe with a cloth that I wanted to go through under the primary it would not go through.. As i looked nearer i saw that the outer primary touch the frame at one point. Its on the front end from the primary.
I can set washers under the front motor attachment - thats not the Problem - but is there a need for?
