Hesitation at Half to Wide Open Trottle

[Guest]

This is a new problem.

I cleaned the carbs this winter, and also cleaned and reoiled the K&N insert with an aerosol K&N kit. I moved and haven't been able to ride much this year, and noticed when I took the bike out that it sounded a bit sluggish and I was getting hesitation around 6 to 7k RPM at anything over half throttle.

I can rev up to redline at anything below half and can hold it there without and hesitation. I don't think this is a fuel starvation issue and my plugs are on the darker side (actually a little too dark), my floats are set at 22mm, and my main jet is +2 sizes. I haven't been able to do a plug chop at WOT.

Yesterday I tried riding without the air filter inside the air box and was able to pull hard at WOT to redline. When I got home the plugs looked a little lighter and more tan.

I tried cleaning and the oiling the air filter again and I'm back to the same hesitation.

Does anyone have any ideas?

Either you over oiled the K&N, or your main jets are too large

I don't think a Kerker requires jetting

Did it run well before?

It ran well before.

The filter is barely red. The instructions said to spray evenly until its a salmon red. I watched a couple videos on YouTube and I feel like I oiled it lighter than what I saw in the videos.

Maybe I'll try washing it again and use even less oil.
