How long since your last plug change. I've had my J-model 6R for just on 40,000km now, and it's asked for plugs with a sharp dropoff in bottom-end torque every 10,000km, like clockwork.
To get at them, remove the seats, tank and airbox (top and bottom halves come off separately; check your filter and clean if, as would be likely, necessary-the ram air drags all kinds of rubbish in there), unplug the coils (integrated with plug caps; no HT leads) and go nuts with your 16mm sparkplug socket.
To get at the #1 and #4 cylinder plugs, you'll need to scrunch the rubber air duct back into its frame passage, which will still get in the way; due to the camchain being on the right and the cylinders thus sitting lopsidedly to the left on the engine, the #1 cylinder plug is markedly more difficult to get at. With my socket set, I have to first drop the plug socket into the plug tunnel, then send the socket extension in after it, and only then attach the ratchet to the top of that. The reverse is required for when you're actually pulling the undone plug out.
just run some good ol BP Ultimate thru it a few tank fulls, and see how that goes.....
Not to be a smartarse, or anything, but why would you think running the bike on LRP would be such a good idea that you'd persist with it for a year?
No premium anywhere near you, or...?
