Snooky, Good question, My outer intakes looked like this with only 600 (yes 600) miles. Maybe be due to the additives in our gas?

how many miles?

Are all the valves like that? 1200miles they should look like new? The valves look like it has carbon up badly for only a 1200 miles.

Have you been lugging the motor, ie low revs due to riding in the wrong gear. You need to give is some revs!!!

You can try using throttle body cleaner to remove the carbon. The bike will initially have a hard time starting up straight after the application of throttle body cleaner.

Slow is smooth and smooth is fast!!

We get some crappy gas these days.

Add some Yamaha Ring Free to your gas on a regular basis.....same basic thing as Techron.

I used to be fast....now I just dream about it.

carbon on the intakes

its oil, either from the valve seals or the rings haven't seated in yet

the old mechanic's trick is to put Marvel Mystery Oil in the gas....Google it

My throttle bodies were really dirty too I think the air box wasn't seated correctly from factory or setup. Maybe this had something to do with it. Thanks for the replies.

Dexron III ATF also works well if not better. Sounds crazy, but I also notice a power increase when I use it. 1.5 ounces per tank.
