EXACTLY!! And like I said, over 51K miles of HARD riding... and when I say HARD, I mean... just ask around Baltimore, MD about the "Scooter", "Scooter Man", "BlackMoon" or "Moon" who wears all black and has a metallic blue (or some remember it as white) Burg and runs with and like a sportbike (and I'm talking 900cc's and up!)! Too many KNOW me now to be missed.
BurgPnoMan, I have an '07 also, bought in '08 new (which, at 2300 miles, your's basically is).
I've been engine-braking it regularly in turns and stops, through inner-city streets, up and down highways, over and under the "buck and a quarter" mark (if you know what I mean), and everything else you can throw at her. Now, she's even been Dark-Sided a few years and about 25K miles (if I remember the numbers correctly... I am getting old now, lol!), which is "supposed" to put even more strain on the CVT and bolt. To be honest, looking at it, there is actually not much damage to the bolt (compared to some others I've seen with less mileage). It's nicked about a half to a full millimeter on each side, no more. The last few pics show this best. (click camera on left side of screen to see actual album and picture botes.)
That said, oil changes regularly (and that's with synth from the 600 mile mark) of Tranny, Engine AND Rear have been essential. Never had any excess metal shavings (trace amounts is, sadly, normal) in any oil.
Can / Will the bolt eventually fail? ABSOLUTELY!
Is it worth the effort to replace it? ABSOLUTELY!
Is it worth taking a chance on running yours 50K+ miles before changes? ABSOLUTLEY NOT!!
Like the guys have said... $6 and 5minutes... if that.
But are the claims of Burgs being "problems waiting to happen" true in general? NO!!!
