Got my f4 back from the shop. It had valves checked, new brake fluid, be coolant, oil change, plugs, and timing chain tensioner. So no my bike growls pretty load from under the tank when it warms up. Doesn't sound that bad on video but it didn't do it before the shop. Any ideas?

 

Don't know about "growling" but your idle sounds high. Set 1300-1500 depending on climate. I keep mine around 1400.

 

check the air box? I didn't have mine on all the way after cleaning my carbs and my bike growled, which if you've ever heard a cold air intake on a car it's the same sound.

If you're talking about that high pitched wine, I'm pretty sure thats the CCT and it normally wines like that. Person before me put on a manual one and it wines, but unless you put your ear next to the bike you can't hear it.
