That, Brian, makes me wary of (some) dealers as they try to cure problms by throwing new components at the bike until the fault disappears. “Hey, it’s only money and it’s someone else’s.”

I normally use my bike throughout the winter so I don’t take any lay-up precautions such as adding stabiliser. It was probably purchased in November as I got little opportunity to ride in December. So, not very old; the only reason I suspected fuel originally was that the bike was perfect when I last used it and had developed this misfire while sitting idle in the garage. The only difference between this period of inactivity and previous years is that I am using Costco fuel since they opened their new station near Edinburgh. I’d be surprised if their petrol is less stable than others but it is the only difference I can think of.

Good question about the Karma scores. I, too, have a negative but no idea why or from whom. Indeed, the same goes for my positives. Surely one can’t receive a “demerit”  for stating a contrary or unpopular opinion unless one is impolite or abusive. I see no need for  so called Karma scores. Perhaps the moderators will kindly enlighten us as to the process and purpose?

An update to my query:
Prior to the significant snow dump, I removed the spark plugs and checked the gaps; all good.
As planned in my post of 12th February, in the absence of suitable coil testing instruments, I also swapped numbers 1 and 4 coils to see if the problem moved with the coil.
Now that the weather has improved, I took the bike out for a run today and she’s running beautifully again. I am now wondering if my slight misfire was indeed the result of fuel degradation affecting that one injector and the fresh fuel in the tank just took longer to take effect than I expected.

Thanks to Tom and Brian for your input to my original post. I love this bike!

I'm a Givi fan but look at Kappa. Same design without the frills and fit Givi racks. I think they're made in the same factory.

That’s the one I have on my R Sport. I’ve exceeded 6kg frequently over the past 7 years with no issues. I think my briefcase with laptop and papers must have been around 10kg.

I do it like this on my R Sport. I don’t know if it works on other models but I’d b surprised if it didn’t.

Fit the stand with one bolt/nut loosely fastened (the bolt furthest from the springs)
Fit the springs. Lever or pull the stand so that the other bolt can be fitted.
I have had my stand off several times and I find this method to be very easy and effective with no need for excessive effort, spacers or friends to assist.

Welcome to the forum! Beautiful scenery and a rather attractive motorcycle you have there, arfikk.
