I picked up the twin brother to yours on Thursday, and I haven't been this happy since I discovered sex.
After years of no bike or a couple of smaller Oriental ones this thing is AWSOME. The engine has the kind of low to mid range brute force torque that nip bikes only dream of, or can only get by winding their engines up to somewhere north of the arctic circle.
Mine has some tranny/engine noise too, but in my case its probably because I'm just not very familiar with the more common "Harley" noises.
One thing I have noticed is that the tranny shifts are a LOT more positive than anything I have ridden before. It leaves NO doubt that its going into gear. Going into first is like there's a truck tranny down there, you can both feel and hear it go in. Is that normal?
And BTW I only paid MSRP + taxes and got the same 10% discount for parts and labor. The salesman may come to regret that one, or maybe I will.
