Sudden change in how bike feels.

Hey there.

So i have a 2016 naked. It has 26xx miles on it. Recently (within the last 2 rides) theres been a difference in the power.
Before it seemed very raw, if that makes sense, now it suddenly feels smoother? With less urgency it feels like. Im not sure how to describe it. It still pulls but it almost feels like somethings off. Not kicking any lights or anything. And im noticing the flat spot in the 4.5k-5.8k range way more like its worse almost.

Any ideas?

Sorry for formatting on mobile.

Mouse nest in the intake? Problem with the exhaust valve?

Id go with fuel first, run a tank through with some good stuff and then start looking at other stuff. Filter, exhaust valve etc as has been said.
A plug check can always give you some good clues as to how the engine is running

Two thousand miles? Any chance you have just gotten comfortable with it now?

Could be a bad batch of fuel I suppose. It happens. If it doesn't clear up with "good" gas from another station, then I'd guess one of the exhaust valves is 'sticking' as @mike d suggested. I got a tiny little pebble in the exhaust valve of my CBR929 and it got 'stuck' in place. It did throw a dash light code, so I'm surprised you're not getting one, but maybe its just a matter of time? Or, it threw a code but not on the dash for you to see it?



It might be an intake restriction of some sort, too, (again, as @mike d suggested.) There is a 'flapper' valve of sorts for the intake. Maybe lift the tank and remove the top of the airbox and look for anything amiss with it. Check for oil up in the filter? Maybe a plastic bag got sucked into the intake snorkle? Mice set up shop in there? Stranger things have happened.



I hope its just a bad bit of fuel. That would be the easiest 'problem'. Try a new gas station that sells TOP TIER fuel (green and white marker on the hose or pump itself that says "Top Tier".) Get PREMIUM, too, just to be sure you are getting good octane stuff in the bike. See what happens after running it for 100 to 150 miles on the 'good' gas. Keep us posted.

I notice this on my bike pretty often. Not sure if it's exactly what you're referring to, but sometimes my bike feels super raw, sounds great and roars, and other times it just feels and sounds...meh. more smooth and buzzy than deep and raw.

My recent guess is mine has something to do with the exhaust valve, and I plan to do some experiments.

That's an observation I've had with gas-powered cars for years. I think a huge factor is the air- the temperature, the humidity, the density, things like that. Some days my Mustang just runs fantastic, others not so much.

Now, interestingly, my Chevy Volt electric car will run the same regardless of the weather. But it's got no combustion happening so the air's properties play no factor at all.

That’s the first thing that came to my mind as well, air/climate/outside temp conditions ... Is that possible Bored?
