18 F3L Shifting input

[acdcking12]

So I have noticed something. When I am speeding up from a stop, and I shift, if I have the throttle steady and not moving it shifts quietly and effortlessly.

If I am increasing speed with increased throttle, sometimes the bike will slightly kick as it shifts. it is rare. Probably 1 time out of 30 shifts, but I do notice it. But only when I am increasing throttle.

It never happens if the throttle is steady.

Has anyone else experienced this and call it normal?

Yes, normal.
The transmission uses straight cut gears, so…..I believe you’re feeling the Engine/ Transmission adjusting to accomplish shifts “smoothly “. Input shaft and output shafts turning at different RPM’s ……ECM and TCM make very quick adjustments to accomplish a shift.
I was startled too when first experienced…….
