Ok, let's see here. All the bolt on the front sprocket does is to stop the sprocket from falling off. The splines transfer the torque. A circlip would probably work as well. Sure we could get all engineery about it but that's the basic function. Leave the bolt out and limp home. Probably why it wasn't replaced like the rest.

BMW went sledge hammer to kill the fly that was the breaking chain. You can re-use the rear sprocket bolts if you inspect them first. Replacing the lock nut is probably a Lawyer/marketing tactic. You buy new parts, BMW makes a profit and pays less insurance. In reality, if the nut cannot be installed by hand, then it has sufficient locking ability to be re-used. This hardware set up is under shear force and in a failure situation, could result in wheel lockup. Imagine if the swingarm nut fell off and the bolt worked it's way out.

The lower shock bolt.....

The upper shock bolt uses a curve design to prevent it from coming out.

There are two types of maintenance. Breakdown maintenance and preventative maintenance. The difference is location. One you do on the side of the highway at night in the rain (Murphy), one you do in your garage with a radio and a few beer on the weekend. To each his own. I'll continue to anti-seize my bolt and spend 30 seconds twice a year to check torque it rather than lock the shit out of it and hope I sell the bike before I need to remove it.

YMMV

I mark the bolt with a little orange paint. (Touch up for my bright orange car)
I also mark sprocket bolts, axle clamps, axle bolts and fork clamps.

Then check them before a long ride.

I am not actually any good at checking but this post has reminded me to do so tomorrow before my next ride.

Thanks Reaver - understood, and I agree.

Like Kiwi I have all of my critical fasteners (that are visible) marked with a black sharpie for a quick-walk-around.
The sharpie seems to last well, and a quick wipe with carb cleaner erases it when I take it down for maint.

Kiwi: I'd add the caliper mounting bolts to your list!

MikeMike · 12-10-2012, 07:02 AM

I would add anything a dealer has touched to the list.

Reaver · 12-10-2012, 07:38 AM

The three screws that hold the plastic front sprocket guard on are always loose. The bottom one is often missing. Side stand pivot bolt - another forgotten tq check item that's always loose.

Just spent two hours going over our new-to-us 658 with 20K kms on it. I would guess no one's looked at it too hard even with full Dealer only service history. Many undertorqued things found like handlebars, triple clamp bolts etc. Wheels overtorqued and chain too tight. All part of the Zen of motorcycle maintenance. Besides, it's "Her" bike.

Just replaced my sprockets and chain this afternoon, while the weather was co-operating and the shop was warm enough to work. The new front sprocket was very tight on the splines, so that's a relief. I was worried the splines on my output shaft might have been worn.

Still have some life left in the tires so my new Anakees will have to wait.

I'm ready for Spring any time now.

MikeMike · 02-15-2013, 01:39 PM

Voice of Homer Simpson...Mmmmmm new Anakees!

The only way those tires could be better is if naked women came to the house to install them and called their twin sisters over to balance them.

I'd settle for Homer himself installing them.

You'll have to add your impressions to the tire thread once you've got a few miles out of them.

JRWooden · 02-15-2013, 02:21 PM

Anakee???
Are those the new Anakee 3?
Wow ... much different than the 2's.............

That's a very interesting tread pattern ....

I'd bet longer life than Tourance .... I wonder how they work in the mud?

Yes, Anakee 3s indeed. We're very interested in trying them out but we're not quite ready to change over.

Hurry ... wear them out

Problem is we've still got good Tourances on the bikes, and I hate to waste tires.

MikeMike · 02-15-2013, 07:57 PM

If you liked the Tourances, you are going to love the Anakees.

We didn't like the Anakee 2.

The outer edge was a row of loose blocks which didn't inspire cornering confidence, but the new series look great.
