i am just going over the bike from top to bottom and when i reached the back tire to check the bearings and axle and stuff i noticed the belt was a little off.

Thoughts.

This can happen if you roll the bike backwards. The belt will normally track back in properly when rolled forward.

Check the lineup of your swingarmbearings.

Do a search, it's been discussed here a lot. It's normal and you don't need to worry about it unless it's scrapping on the belt guard.

I'll go out and get a pic of Loretta's belt after the sun comes up.
Her belt tracks a little off too.
I don't think it's quite that much tho.

I just pored over the FSM and there is no mention of a spec for belt engagement.
There IS a spec for runout of the IDLER pulley : +/- .010", total runout < .020".

The front pulley has lips on inside and outside, belt can't come off unless the idler is bent.

My belt tracks exactly the same as the one pictured above. I was worried too until I did some searching (on this very board) and learned that the belt track is within tolerance if it's within a 1/4" of the inside edge. So; no worries - carry on!

And what about the slight fraying of the cords in the belt (see the photo at top)? I notice the same thing on mine, to about the same degree. Any cause for alarm?

Keith, glad to see you got the thing home! Whatcha gonna do with that front end ?

My belt is right about that same spot , that's why I took off my guards so the belt wouldn't fray anymore not to mention the sleeker looks.

Looks just like mine, might as well snuck in my yard and snapped that pic. I used a dremel to widdle down the belt guard to prevent rubbing. A heavy duty file would have the same effect if you don't have a dremel.

All you have to do is take a washer or two and shim the belt guard out. No need to file or alter the belt guard at all.

The fraying, if I understand the manufacturing process correctly, is from the belt being "cut" from a sheet of "belts". I seem to recall they make the belts in a multi-foot-wide panel, then cut them to width. The "fraying" is just where the cross-weave cords are cut.

Your dead on Ratbuell. All cut belts (which is pretty much every manufacturer's technique except Optibelt who uses an extrusion process) have cord fibers exposed.
