For years I have greased all nuts and bolts on assembly, with the exception of wheel bolts. Never had a problem and they are always easy to undo next time.

However, I now have two things I never had in the past: the Internet and a torque wrench.

So, apparently using (lithium) grease on a fastener:

is a good thing because it overcomes friction which would decrease torque values

is a bad thing because it overcomes friction and will increase torque values

doesn't matter because my torque wrench is wrong anyway

doesn't matter because manufacturers allow safety margins in the torque figures

doesn't matter because in any case my handlebar mounting bolts are going to snap, my rear shock will break along with my drive shaft, my rear brake will seize, my electrics will get on fire, and my rear wheel will fall off. AND my rear shock stud, which started this train of thought in the first place, will snap (though I do now have a support for this stud, courtesy of Sidecar Paul).

I know where you're coming from!

I think this will be more entertaining than an oil thread!

What do I do? I put blue Loctite on everything.

Ha, we are tyred of oil threads...

We use Loctite here too, but its black.

On a more serious note it is quite a significant topic andof relevance to K owners.

threadlock's probably great insurance where the specified torque on a fastener is mainly about ensuring it doesn't come loose. The more critical ones are obviously cases like the lower mounting for the rear shock that seems to suffer from reduced fatigue resistance if too loose or too tight. At least if you use thread lock you are not as tempted to make it too tight!

What's wrong with green Loctite? It's oil-resistant too (see what I just did Olaf? Cool ).

Did you read the intro of the new member with the trike?
The PO found the solution: Cheap and efficient as the nuts will never break loose. WELD them!
