Well, ran through whole tank of fuel with fuel system cleaner, nothing changed in terms of how engine works. Vibrations are most felt at idle and 5k+ through the seat and pegs. Anything else to check before tackling valves?

Okay, back from a test ride.. wow, what a difference! I’d say 70% of the vibs are gone, it’s so smooth now compared to what it was previously. Remaining vibs are felt from 5k and up, mainly through the seat. Vibration is very high frequency, I’d say inline with engine rpms.

I totally agree on this, but just out of curiosity, wouldn't leaky valve/bad ring/head gasket would cause issues with general engine performance like idling, oil consumption/leakage, loss of power etc.? My engine runs and drives fine. I've added fuel injection system cleaner yesterday too...

Well the chain noise has not changed significantly and the vibrations seem to still be there, although I could’t test drive the bike - it was pouring rain. However, vibrations on idle still are there. Seems like running out of options.. no idea what else could cause those vibs. Now the only...

Well, all the engine mounting bolts are torqued, CCT swapped, although the old one looked and worked just fine.

Most of these have already came to my mind!

I hate that person now.. So much fiddling for such a small issue! Will tackle that bolt today and my CCT arrived just now, so will change it out too.

Last bolt remaining (and the most problematic) holding the crash bars at the top of the frame, where the fairings would be fitted on a faired version. Quick question - is there a nut holding the bolt on the inside of the frame? The nut is not coming out and it seems like a nut is holding it in...

Did the spark plug wires again, cutting more of the wire this time. Everything went much better this time, plug caps screwed in tightly. No change in vibrations. Engine mounts, crash bar and valve clearance seems the only remaining options. Going to tackle mounts with crash bar tomorrow.

Negative, that's a pretty long and big job that I've never done before, so I want to cross all the alternatives and then get to it. Will re-check the wires later today, can't believe they had no impact, seen a lot of good comments here. Maybe I've cut too little (I've cut only a couple mm) or...

Unfortunately no, I do not. But I now remembered - wouldn't it create 218mmHg vacuum at sea level?

Excellent advice, thanks again. Ordered some helicoils and will try to tackle that bolt once they arrive. On a different note, last night I checked sparkplug caps and leads to see if they are not loose. Would you be able to spin them with a bit of force after they’re snug? I cut the leads with...

Okay, that's new information, thanks. So the hole on the right side has no thread - how is that bolt supposed to stay there? I can pull it out with my fingers, I don't get how it remained there this whole time and didn't fall out. Left one seems to be just turning with little resistance and I...

So the top bolts that screw in directly to the frame and hold the crash bars is a mystery to me. Came to try again the next day, tried to pull on it with pliers - it's out. Seems like there's little to no thread there. Same bolt on the other side is not coming out and is still turning with...

Probably will just buy hex head for my wrench. Will try to use a flathead screwdriver too, thanks for the tips Gary.
