It is either wrong belt, stuck pulley(s) or both.

Injector cleaner works great if you have valve deposits, likely from high mileage.

Oh my what is that LOL?  Can you direct me.  What is this and where do I put it.  All I know to do is put some seafoam in my gastank now and than. :)

Not sure what you have in N America, but PEA-based cleaners work well. I think Lucas upper cylinder lubricant is ok, but there could be better ones on the market.

You just add it to the fuel tank and after a few hunderd kms you will notice a power difference.

Fuel Injector cleaner - is that proper to ask for when I go to Canadian Tire or bike shop.

SHELL and BP (and several others) gas companies in the USA sell Top Tier gas. Shell and BP are recommended by BMW, VW, Mercedes, etc. and come with plenty of "cleaners" in the mix.
When used regularly no additives are needed.

And, I'm feeling a little peculiar.

Have no idea how a low battery could have any effect on high rpm. Low battery will allow starter operation but will not fire the plug below 10.5 volts. Other electronics like speedo and tach are not as voltage fussy. Had you had actual sound on your video it would have confirmed the tach.

 I can easily upload a clip with the sound.  I didn't know it matter.  I am stupid with all this! :D

Don't say stupid! Ignorant can be fixed but stupid is forever! Even when ignorant is fixed, retraining is periodically necessary, like keeping mph and kph straight (me!). Many on here have been listening to engines and drive units so long we are nearly deaf but sometimes can still hear things that tell volumes of info. There was a post on here years back that indicated by the sound the rider adjusted his valves with the cam in the wrong position: LOUD CLATTER!

Sounds like 7 to 8000 rpm when the tach shows that. Looks like speed is pretty slow.

Yes I think I use my bike pretty regular.  I even get it out in the winter not often but  do.  Lets see I have had the bike 3 years now and I have 28000km's.
