Splines and lubrication

[iboldguy]

Just changed both tires (to Avons) with a lot of help from a friend.

Pulled the pumpkin and drive shaft. The rear wheel drive splines were well lubed.

The universal end of the drive shaft had no lube and was rusty yet. :blink: No damage that I could see. So lathered her up with high temp grease. It may be that the Yamaha engineers know what they're doing and those splines don't need much lube. Although I can't see what harm greasing will do.

new to me 2006 2nd owner, only about 10,000 miles.

BTW the saddle bag lock screws were not lock tited - are now

YEA,they most have a reason to want to allow rust !

The trade off is wear from attracted grit/contaminants, versus no lube/less grit. It's really hard to find a grease that won't attrack sand and other abrasives.

I spent a couple hours breaking mine down today, cleaning and re-greasing everything. It's been about 20,000 miles and 10 months since the last time it was done. I wash the bike frequently and was still very surprised to see the level of sand and grit in that region.

Seems like it's just one of those areas that you either service regularly, or leave it forever and replace all the pieces at once when something fails.

I spent today prepping the bike for EOM: New PR2's, New Oil & Rear Diff Fluids, etc. Pulled the Pumpkin & U-Joint for the first time since February (12.8k), and found them bone dry and gritty. I gotta start paying more attention to that.

I opt for the latter. If it works for Scooter G, it'll work for me.
