Severe Lugging - Fueling / PC / Electrical Issue?
Wondering if you guys can help point me in the right direction in figuring out what is going on with my niner.
Issue: Bike is lugging / surging at low RPM, occurring most consistently around 3k rpm. Symptoms are lesser as the revs go higher. Bike has been cutting out occasionally both at a stop (idle just drops under 1k rpm and the bike might just stall then) and at speed, including on the highway. That was scary. I have also noticed that it is running hotter than normal, although nothing close to the red bar (more like halfway, whereas it use to barely go up). Maybe this has nothing to do with the issue.
This started yesterday on my way home in the afternoon. Outside temperature was not very high (18c or so?). This morning (about 11c, not perfect but not serious. Today late afternoon (about 24c), very severe, to the point that I don't want to ride it this way. It cut out a few times.
My bike has about 28k km (17.5k miles or so), and recently had valves adjusted and spark plugs changed. I have only had it since last summer but it has been nothing but reliable in this time.
I do have a PC3 with one of LDHs maps that was added in late in the season - the PC is hard wired so likely this is not a loose wire issue. I admit that I don't really know how to use the PC3 (hooking it up to laptop, resetting it, etc) and will read up on that to check it out. I think that the PC could be one possible issue.
Besides the PC3, what other checks should I be doing? I saw that someone here with similar issues had a crack in the spark plug boot (or something like that). Anything else I should check?
