Honda Moly 60 is discontinued, Guard Dog Moly can't be found either. I haven't heard of a good replacement.

I've been using Loctite LB8012 moly paste for the past six years. 65% moly, seems to be readily available, sometimes packaged as Loctite LOC51048 or just plain Loctite Moly Paste.

 

Searching Amazon for Honda Moly 60 only turns up Honda HN 08798-9010 (M77). Looking for the the MSDS for that, I'm taken to the sheet for Dow Corning MOLYKOTE® M-77 paste, so apparently it is just re-labeled for Honda.

 

The M77 might be a better choice than the Loctite just because it is available in small tubes. Costs/ounce are not that different, but I have enough Loctite that I might need to mention it in my will.

I know there's already been discussion about this on wetheads elsewhere, but what's the consensus? Should the rear splines be inspected/lubed regularly and at what mileage? As far as I can see there is no schedule in the manual.

Obviously BMW engineering doesn't think there is a reason to do so.

 

It's not a sliding or wearing area so the lube is mostly to keep the spline joint from rusting or corroding tight.

 

I haven't seen much being done on this with the wethead yet but on the older 1200bikes I have seen a few that were worse off after lubing as the person doing the work didn't get the gator boot re-installed perfectly & that allowed the spline area to fill with water.

Over on advrider.com, there's a long post about doing it to prevent rust as several owners have found significant amounts of rust on the joint or driveshaft on their wethead R1200GS.

I might take a look at it when I do my 30k mile service which is coming up soon. I remember reading about the problems of the gator boot seal so I'll be careful to get it right. Reading the manual, it doesn't look like a big deal to inspect it. I tend to ride rain or shine so I have been in a few rain storms.

My opinion had always been a resounding NO! No harms done in lubricating the spline (nothing gained either), but there can be some serious harms done IF you do NOT replace the rubber boot correctly! I am a bit tired of explaining the reason, but Google u-joint failures for the 1200s boxer. Happens more often with the GS/GSA crowd, especially ones that frequently ride through water.
