My bike, before i crashed, was a maintenance nightmare, but damn pretty to look at and a blast to ride.
Here's a list of repairs and where they were done:
'02 F4S Diamante
New Alternator/Battery - Beaudry, ID
Right side fairing and belly pan melted by header. replaced twice, once by East Side Motosports, WA and once by Motocorsa, Portland
leaky gas tank, replaced twice - once by East Side Motosports, WA and once by Motocorsa, Portland, 2nd tank damaged in shipment 3rd tank was scratched as well, had to be repainted.
Replacement battery went tits up, replaced myself
multiple coolant leaks
Rear break fluid reservoir boiled off by pipes. Replaced with race brake fluid.
By my estimate, there have been about $5-6K in repairs done on my bike.
Eastside Motosports dropped MV because they wouldn't reimburse them for warranty claims mine in particular.
When it was at Motorcorsa, the last time, Matt Stutzman

from MV NA wanted me to sign away my warranty rights due to the multiple repairs for the same items, ie tanks and fairings problems. The fairings were melting while the bike was in the service bay warming up!?!!?! I refused to sign.
That guy is a piece of work. I can not say anything good about him.
