I have put this in here, as I found it funny that I managed to forget it during my two "K" bike

ownership.

I LUBRICATED THE THROTTLE ASSEMBLY...........

I also checked for free play between the grip and the Bar end weight as per instructions from Rossko

But what a difference ...a different bike

I now recall an article in a british bike mag, about a young guy who took his bike to

a shop, who advertised very cheap tune ups.

When the bike came back, and duly found to be much faster, the guy enquired as to what was done to

improve the performance.

Guess what...

He lubricated the the throttle assembly...

nuff said.

One portion of humble pie coming up..

On lubing the throttle: years ago, at a BMW dealership in Oregon, whenever someone brought in an Airhead with 32mm carbies needing a full service, after the required work was done on the engine, valve check and adjust, ignition timing check & carb sync, a 40mm throttle cam gear & chain was fitted into the throttle housing and properly lubed - a similar design to early K bikes. It was only a few dollars back then.

The more radical 'ramp' of the larger carb's throttle pull would make an amazing difference in revibility and response. Just like a quick turn throttle.

Against general consensus I lubricate all my cables with a PTFE lubricant called Triflo. It is compatible with the Teflon liner and will not degrade it like some other types of lubricant. I added a grease nipple to the clutch arm and I also grease the lever pivot points and lube the cable nipples and grease the throttle gear assembly. My Brick is now 26 years old I've owned it for 21 years and still on it's original cables. I have however replaced a couple of levers. Anything that moves will benefit from an occasional lube with the correct type of lubricant.

Regards Martin.

I too fitted a grease nipple to the clutch arm, lube the nipples, and lever barrel.

A new clutch too, and the action is very light.

Having recently renewed the front master cylinder, you would have thought I would have noticed

the lack of lubrication..

My K is a delight when filtering at low speed, even more so now.

Having worked with OEMs for many years my understanding of the oft-repeated statement that new cables should not be lubed is more like that they should not need to be lubed like in the days of yore when cables were not lined. If TriFlo works for you then no worries, it may be a good idea.

In fact, most BMW OEM & replacement cables have had liners in them since the early to mid-'80s.

I'll give you another good reason for lubricating lined cables. The exposed bottom section of the inner gets covered in sh!te and drags it up into the liner for around two-three inches. The result is teflon-backed grinding paste which doesn't do the inner cable any good whatsoever, no sirree.

You're right Dai, when I spray in the Triflo I spray until it runs clear. The first part to come out can be pretty grotty. Another little trick I do is to pack the rear master cylinder boot with heavy silicone grease which stops the ingress of water and road crap and stops the corrosion that effects a lot of rear master cylinders. And I have only replaced leaking front shock seals once when I first got the bike, twenty years ago. I now pack under the dust boots with silicone grease, whether it has extended their lives who knows. But it can't hurt.
Regards Martin.

Listening to Martin go on about Triflo made me go and get some from the local bicycle shop.

I've used it on various cables (including my K's) and it works a treat.

Sort-of-like DeoxIT for cables.
