Clutch adjustment - Hard shift

Post by KCwing » Thu Sep 21, 2017 3:50 am



First of all I appreciate the feedback I have received up to this point; invaluable to say the least.
I am working the kinks out of my newly acquired 1978 GL1000. This is the first one I have ever owned. I have enjoyed the process up to this point, although frustrating at times.
I am now seeking advice in regards to my bike shifting hard, at least I think so. I also own a 2013 CB1100 and 2010 BMW 1200GS that shift seamlessly.
My question is this: Am I expecting too much from by GL1000 that is 40 yrs old or should it shift like my two newer bikes? My GL1000 is running great with the adjustments I've made, however, I can feel the shifting as I move up and down on the gears especially at slower speeds and going from neutral to 1st gear. I have adjusted my clutch to the T as Randakk suggests in his blog tutorial (http://www.randakksblog.com/clutch-adju ... #more-1397) with very little difference. Should I do more adjusting at the handlebar perch or lower cable adjuster? Would I be better served to tinker with the screw adjuster a little more? Is a slight hard shift doing damage to the clutch? Once again your comments and suggestions are greatly appreciated.

Compared to other bikes and the ones I have now, the GL1000 has the "clunkiest" transmission of any of them. It must be the nature of the beast being these tranny's have straight cut gears. Sometimes it shifts really hard and requires a really "positive" hit on the shifter. I find neutral between 4th and 5th often. The clutch is adjusted according to the owners manual.

I have a Honda 500 Shadow and a GL500 Silverwing and the transmissions are smooth as butter.

The GL1000 is still not as clunky as some Harley's I've heard. Sounds like the tranny is going to drop out of some of them!

On a side note I really love the whine of the transmission as it winds out. Sounds like no other bike!

Well that makes me feel a little better. I have a tendency to over analyze and that's what I like about this forum. It helps me put things into perspective as I am a rookie with these old metric bikes. Maybe some others can shed some light on this as well.
Thanks!

I do not use the clutch to up shift. I just load the shifter up a bit, then let off the gas to get an upshift. A bit smoother unless you are in a real hurry. If in a real hurry, it is much faster that way but not smoother. Using this method, I get neutral less often by accident and never get the false neutral between 4th and 5th.

Interesting technique...I assume this will not harm the clutch system?

My 76 also shifts hard into 1st. The other gears however are no different than my other bikes.

The oil I use makes a big difference in shifting. When I changed from ? 10/40 to Delo 15/40 the shifts became much smoother. This applies to all three of my rides.

The engine oil is shared with transmission so it does matter. Using a motorcycle specific oil helps. I run Rotella T6 synthetic in the blue bottle. Never hear of anyone damaging a clutch or transmission using my shift method but certainly there is potential and extra gear wear when under full throttle.

It very well could be my oil choice. I running Castro 10W 40. I will be due an oil change soon. I will try one of your recommendations.

I have never tried a non-motorcycle oil, but others who tried said shifting is easier with proper motorcycle oil.

It won't, no, because the clutch is not engaging/disengaging. It will however, wear the dogs on your transmission gears. The more difference between the engine and wheel speed, the more wear (i.e. poor engine speed matching).

I don't know about you, I'd prefer to change a clutch over changing transmission gears.

Good point...I agree 100%
