Just got back from sailing my boat back across the Atlantic . . . and my Zero was waiting with a new motor at the new NY metro dealership, Rockwell Motorcycles.
Rode the bike the 25 miles to work -- cant say I noticed any difference in performance -- but I didnt try going flat out on the windy roads between Newburgh and White Plains, and with an expired registration in my pocket.
I dont mind the different motor sound -- its like the high tech sound of the old motor, only more so.
Zero did the entire repair under warranty, including hauling the bike to the dealer, so I am really happy right now -- its great to get my ride back. Rockwell Motorcycles seems really enthusiastic about the Zeros -- they are already the no. 2 dealer in the country, apparently.
So I am a happy Zero owner again, for now
