This bike is getting annoying or Yamaha is everything I've brought it back for the dealer and Yamaha says its normal but yet I was told it should not backfire at all when left stock and the speedo is normal to be 10% +or- 1-2mph. and popping out of 2nd or going for 3rd and it not being there in normal but yet they are issues I was told I shouldn't have. anyone else have these issues? oh yah for the speedo I was told to by a aftermarket part to fix it and for the backfire I was told it's not backfiring its popping and if I want to fix it I have to install a programmer witch any of these will void warranty if found to directly effect any broken parts. which I know they will say.
