Title: Throttle Cable Adjustment
Post by: White Dog on March 25, 2016, 12:37:21 PM
Hi, I just purchased a 95 K75 Std.  The twist throttle has almost 1/2" free play.  Is there an adjustment to decrease the free play?  Can't find anything in the owners nor Clymer manual yet.

I might add I reside in NC and have never owned a BMW before but have longed for one for years.

Welcome Whitedog you can find the adjustment next to the brake master cylinder, it's covered by a rubber boot. you should have  0.5 to 1mm free play. Once you have done the adjustment you will need to check the throttle position switch (TPS) adjustment as outlined else where on this forum.
Regards Martin.

Welcome, White Dog.
In my Third Edition of Clymer, it's on p.243 in Chapter Seven, Fuel Injection System, Emission Controls and Exhaust System/Fuel Injection System Adjustments/ Throttle Cable Adjustment.

Thanks for the prompt reply.  I just didn't look hard enough in the repair manual but I have the same edition and it should be a simple adjustment.

greetings...

if you caints getts it adjusted to yourn liking... sometimes its cause the cable has stretched over time because the previous ridor was not a smooth throttle operator... if thats the case you are gonna need a new cable...

it takes tremendous motobricking skill to be a throttle whacking throttle chopping sliding high siding ^quintessential motobricker without stretching the cable...

the key is keeping it on the red line...

When I ride twistys I keep my throttle pegged to Red line and control speed by slipping clutch.......that's real skill.

Before you go into the adjuster, make sure the end by the throttle bodies is seated properly in the bracket that holds it.  You will have to reach in from the other side, going in behind the radiator in front of the air box to grab the cable and work it back into place if it is out.

Then take the cover off the throttle mechanism on the perch and make sure the the two marks are aligned.  If all that is correct, then make the adjustment at the adjuster.

I'm ignorant to the term "perch".  Where is it located and does it have any other names?

Best tastin' fish next to walleye.

The perch is that thing that holds the brake, switches and throttle on the handlebar.  There is one on each end.

Is "perch" what BMW calls it?  I had trouble getting signed up for this forum because I was not using the challenge words BMW wanted, even though I was looking at my owner's manual trying to register.  I finally just entered "brake" instead of front wheel brake lever, etc.  and Voila! I was in.

OK, The official BMW parts fiche calls it a "Housing".   Does that help?

Housing tastes even better than Walleye.

Walleye is easier to prepare.

If it is the same set up as the K100, there is an alignment marker right next to the throttle. Remove the big Phillips head screw next to the brake master cylinder.

To quote from the downloaded manual (steering section, 32.07)

"When installing:

Before assembly, grease the actuating cam, twistgrip
teeth and handlebar end.

When assembling, make sure that the mark on the tooth
ot the twistgrip is aligned with the mark on the actuating
cam."

This might get rid of a lot of freeplay before the final cable adjustment.

Johnny: excellent picture of the perch. My family and I travelled from Littleton Colorado along the Rockies and into BC Canada in 2012. My son and I went fishing one evening at the Yoga Ashram Kootenay Lake (wife and daughter doing their devotions on top of the headland while we were below). We caught 10 green and gold perch on a single $2 walmart spoon lure (yellow and green... juvenile perch I suppose), 9 the next night then only 3 on the third. They'd wised up I guess. When I suggested to my 8yr old son that we catch kill and cook one of the fish he was all for it until came selection time. Then he burst into tears and couldn't do it... yet. Beautiful part of the world. The "Going to the Sun Road" was something special. I'm sure many of you have done it.

Thanks for the responses.  My throttle cable adjustment was an easy fix.  The marks were not aligned to each other on "the perch".  They were off one cog. 

On another note, I found out via the web my low profile seat number was changed sometime ago.  The German website for BMW was where I saw the change.  Some dealers' parts fische still have the old numbers--well most of it.  The last 3 digits of the part # seems to change for whatever reason.
