Thanks so much! I may have imagined it but at the end of a ride a day before I noticed this I thought I heard a clunk (but I think it may have just been the clutch).
In terms of cleaning at a carwash (and this is going to be a totally dumb question) is there any danger of dislodging hoses, lines, or connections with the high pressure spay wash hoses? Obviously with a car one's engine is shielded.
This is a truly great forum, and I thank you all for the quick replies on this topic, especially yours Serowbot: I thought storing it vertically would help save space
