Loud/noisy and loss of power

I have 2016 KLR and have done KLX kit (142 clip on 2nd , 42 pilot , fuel screw 2.75 turns out), L mod, two bros exhaust etc.
Bike runs great and memorial weekend i took it to for first long ride around 1000 miles to finger lakes from NYC. It pulls well, runs smooth and I love it but i notice after riding for 70-80 miles it sounds so loud and noisy. I also feel loss of power! If take a break for like one hour and ride back again, everything is normal bike is smooth again power is back but again after riding 70-80 miles it does the same thing. I was wondering if any one knows why this could be happening?

It loses power, but still runs at 80 mph? How is this power loss detected?

Without losing power it does 95 mph and does it smooth like butter! may be my klr runs better better than your's hahaha

When I say I detect loss of power I meant when it is running fine it goes to 90 plus so smoothly and when I have this issue, very hardly i can push it to 80...

lonsomecrow,
Your description does not make much sense to me either!

Can you touch the rear TIP of the rubber chain Slider under the swingarm, when you lightly Push UP on the drive chain?? If Not, Loosen the adjusters until You Can!

YEA, I know that you think this comment is "OFF the WALL"!
Check your chain slack!!!

I have to agree with pdwestman, this sounds like a chain problem.
I also have 40+ year on old Harley's and British bikes. A bad or over tighten chain will shake the hell out of things.
I had 1 on a BSA that would start shaking about 65mph and slow the bike like you had a flat. It was a binding chain.

After you adjust, roll the rear wheel a full turn and check again, if it's not the same you have a bad chain.

Ok I ll check the chain slack but how that would affect the loud and noisy sound?

Is this "loud and noisy" increase in sound from the exhaust, the engine, the tires, the wind ..... ? Any chance it occurs after a turn in the road? At that speed a change in the wind relative to the direction of travel can make a noticeable difference in engine load and wind noise.

If you spin the wheel, and there is a tight spot in the chain slack, then it goes loose again, does that indicate a chain issue only? Could there be any other causes for difference in slack when rotating the wheel?
