The 2017's slipper clutch may have something to do with mine having no drivelash, while Eric's '14 Standard had a lot. At the time, I attributed his bike's drivelash to a loose chain, just as I attributed his bike's heavy steering and rough suspension action to worn, squared-off tires.
I don't know. I just know that my '17 has no drivelash, on or off the throttle, gently applied, or hard on the gas.

(+1) Sounds about right for me ('14).

can't recall ever double clutching the CB... just saying...

It would be interesting to compare the two bikes, especially since Honda front suspension now uses what would appear to be a better fork, with damping handled by the Showa Dual Bending Valve system. Also would be interested to observe any difference between my 2014 and the newer bike with slipper clutch.

Perhaps you were thinking rev matching?
Double clutching requires going to neutral and releasing clutch between gears...helpful with a non-synchronous trans.

Hard to double clutch on a bike, I’d have thought, other than between 2nd and 1st.
RE: I think I've asked this before (drive line lash) - jimgl3_imp - 07-16-2019
yes, exactly. a previous poster posted "I don't think our CB1100 tranny would be defined a 'synchronized." I was being facetious

Sorry to bring up an old thread. I notice my CB front sprocket can still turn about 1 to 2 tooth position after I engage the gear (stationary with engine stop). I am wondering if this freeplay is what Max explain here, by design, or I had damage the gear. Sometimes when I upshift on the higher rev range I kind of miss it and end up in a kind of false neutral before the gear suddenly engage in a violence way (either up or drop back) with loud grinding and banging sound. The 60mm freeplay Max explained here, is it the distance the chain can travel front and back when gear are engage with a stop engine?
(07-14-2019, 02:35 PM)max_imp Wrote: Being curious i just measured the lash in all gears of the rearwheel, the first three gears are identical and have 60mm. travel ( freeplay or lash ) at circumference, the cushdrive in the hub has no play but some flexibility.
The chain has 5mm. play, that is about 10% of the total.
The chain tension is a conservative 40mm. between top and bottom movement.
As a reference the 40 year old cb550 measures 50 mm play when in first or second gear, so not much change there.
And Jim is exactly right, it shifts fine clutchless, when slowing down i apply a small amount of pressure on the gearlever, reduce throttle until it shifts down etc.

Zirconxi i have just uploaded a clip with all the different ways to measure gear lash on our bikes.
Hope this helps you.

Interesting vid Max.
Question, where it says this is "how I adjust chain", are you just showing before and after free play? I didnt see you doing any adjusting.
