noise from my '17 F3 w/1700 miles

[tip]

A few weeks ago I posted on another thread about loud noise coming from my F3.
Took it to dealer on 6/26/17 at which time they replaced the following:
Changed rear wheel
Replaced rear wheel bearings
New rear tire
Drive belt
Belt tensioner
Switched out alternator
Replaced front and rear sprockets
Nothing changed - so they suggested that I ride it some more to see how it reacted.
Noise first started mid 40's - now makes noise between 19 and 23 mph - approx. 32/33 mph and from 38 to upper 50,s
being very loud.
500 miles later it is getting worse and dealer has contacted BRP. BRP suggests that I either
get another bike or change the transmission assembly.
My decision is to get the new trans.
Anyone out there having similar problems?
