I`ve just orderd bearings,axle and wire from Motor-bins.
My clutch action has been a little stiff and I`m about to improve it.
What do you think about fitting a grease nipple on the arm?
I think Motorworks got one listed.
Cheers,Wikur!

Just drill it, tap it and fit a grease nipple. Very easy to do. Should get grease nipple from any agricultural parts supplier or garage.

Thanks Avenger!
I was about to do it myself,got the idea from Motorworks.
Strange that BMW didn`t do it from start.
I`ve never heard that this is a common problem on K`s tough.
My cluth cable is from-88,never been replaced.
Maybe the wire is beginning to cut through the teflon coating?
Cheers,Wikur!

Actually it is a common problem, caused by the rear mudguard being too short at the front. Water and muck get dumped straight down on to the clutch arm. My own one was half seized but I managed to get the rod out of it by tapping it over and back a few times to loosen it. I had another on a friend's K75 that was so seized up that the rod was turning in the two lugs on the back of the gearbox. I had to cut the rod with an angle grinder to get it apart. Better to sacrifice the clutch lever than break the lugs off the gearbox!!!!!

i guess it should be serviced every now and again ...its a needle roller isnt it ?

Yep, needle roller.

its amazing isnt it ?...anybody else designing and then building a production bike would just put in a brass/plastic bush .....

20+ years and it still works ....omg ..stunning

The later bikes had an extra flap on the front of the mudguard to prevent most of the fouling of the clutch mechanism.

I made a mudguard extension from an old plastic oil can. Light and flexible and does the job.

Looks good!

BMW has an extension part available I wrote a post about it a while back when I fixed mine. One comment made at that time was a spray of chain lube on each end of the clutch are on a regular basis prevents any water getting in and seeps into the rollers. I have given mine a shot once every two months or so since then as well as fitting the extended guard.

Vot is dis chain lube you talk of K BIKE it is a foreign concept to us.
Maybe you own something else you are not telling us about.

Nice work Avenger!

Top job blakey, yet another mod Penned in to do

BIG D

This is what makes this board great. Guys coming up with excellent ways to improve the ol girls and sharing their result!

Thanks Blakey!

OG

cheers blakey nice work

Excellent work Blakey and I shall do the same in the future, I still think the guard extension is worth putting on to keep the spray of filth away from the cable.
Regards,
K-BIKE

I'm doing it right now guys. Thanks again for sharing!



OG

Hey guys...here's a tip!

Drill the hole straight!

K-BIKE, you are right. Install the extension as well.

Lol, after looking at the shape of the arm i'm thinking that might be easier said than done Blakey!

OG

Ol' ham-fisted me stuck it in a vice and went for it.

I was going to say don't forget to clean up all the swarf, but I won't 'cause you guys know what you're doing.

Hey Blakey,

I'm sure I've said it before, but I usually like to screw things up at least twice before I start learning anything so any and all advice before the fact is always appreciated!
