Marik,
Welcome and congrats on the new bike.
I bought my bike a year ago June for $7,800.
Todate I have over an additional $2,000 in after market parts on it and it does not seem to end.
So get use to it.
As far as the OEM tach. It does what it suppose to do like everyone else I do not like the position of it.
After you get use to your new bike it will let you know when it wants you to shift. Seat of the pants thing.
