Title: Shit lever free play
Post by: BearTrap on April 05, 2018, 04:39:43 PM
I’m just throwing this out there since I cannot find a definitive answer to the shift lever free play for a K75. I have been experiencing rough shifting between 1st to 2nd and 4th to 5th.
 
In neutral the lever has a .75” travel up and down before meeting resistance. Shifting into 1st is a full 1.5” before completely engaging. 2nd, 3rd, 4th and 5th all have a full 1” travel before engaging.
 
Does this sound normal? This is my first BMW so I don’t have anything to compare it with.
 
1990 K75 Standard
53K on the clock.
Recent complete spline lube and clutch inspection.
Clutch cable properly adjusted.
Fresh 80wt gear oil.

hi
I am certainly no mechanic but if you enter "grub screw" in the search box above , some of those threads may help you out.

Read this. (http://www.motobrick.com/index.php?topic=9353.0) Does it seem like what you're experiencing? It's understandable that you've characterized it as you have in this thread's title. :giggles

Start at 1:05. Have some coffee. His soothing voice can lull you to sleep.

Shit lever is right  :eek:  Thanks for all the feedback. Looks like I'm gonna have to pull the tranny to get that grub screw tightened up.
Cheers

Damn! My bike doesn't have a "SHIT" lever.  , I knew for their time these bikes were advanced. Fuel injection. ABS. But I have to pull over n stop............unless I am going well over the posted limit and some fuckin idiot at the intersection pulls out in front o me.

After watching the video, I have determined that shift lever does not have any play. She is tight! :clap: No need to pull the tranny. I guess these bikes have a long throw to engage the gears. Anyhow, I still love my K.


I will soon be posting a review on my experience on my new Shinko tyres.


Cheers! :2thumbup:

Also, try more "shit" lever and less clutch.  You only have to put a little pressure on the clutch control rod to get disengagement. And it should slip into gear like butter!

I'll give that a shot.

+1  A short, quick snatch on the clutch when shifting almost pulls the transmission into the next gear.  Barely a half inch of pull is all it needs.

When riding two up with my wife I often don't pull the clutch at all, just very slightly roll of the gas and shift up .. that way there is a less of a chance of the missus headbutting me from behind when I shift!

greetings...

shifting without clutching the motobrick can reduce clutch life by as much as 50%...

I am sure you are right but searching on the internet I found a huge variance in opinion. I do see videos saying it is bad for the dogs and others saying it is fine but since the clutch is never disengaged I do not see how it can hurt the clutch.  Either way the risk of hurting the dogs is enough to make me stop doing, not that I did it a lot in the first place.  Shame, a well executed clutchless upshift is very satisfying
