I would like to say thanks to all for trying to help with the Avanti hesitation. I still have not figured it out and have not heard from the Techs yet. I had resigned myself that this just might be a quirk I have to live with when Thursday my rear tire went flat.
I pulled the tire and found the offending metal (looked like a shaving about an inch and a half long) sticking through and pulled it out and repaired the tube. I replaced the tire and it is holding air. However, after the repair I lost speed. I was averaging 40-42 mph, and now it maxes out at 35-37mph.
What would be the reason for the loss of speed? The only thing that was removed was the brake cable and the outside bolts of the tire. I did not touch the locking nuts (on the inside). Nothing appears to be rubbing and The wheel looks to be in align (not wobbeling). I inflated to the proper psi (as specified in the manual) Any ideas?
