Dirty Valves
Okay I did my valve clearance check today on my 2007 CBR600RR. My intake was all .008 and two were .007 and my exhaust side was all .011 and two were .012
I don't think I have any issues there do you guys?
Second question, I looked into my cylinder ports below the throttle body to see my valves and here is what I saw:

The top of the valves look like black sand paper. The bike has 23,xxx miles on it. Is there a good way to take care of this? Will a good injector/fuel cleaning additive work for this or is it too late? I don't want to clean it in place because it is basically carbon and I don't want to risk scoring the cylinder walls. Any Ideas out there?
Final question, since I am this deep how do I check if the spark plugs are okay? At $100 for a set I would like to keep them if they don't need to be replaced.
Thanks for the help,
George

But lots of people seafoam cars, not sure on the specifics of the bike, but its safe.

On my F2 i actually poured a small amount of seafoam onto the valves and let it soak for a day. It was a little hard to start(think i shoulda mixed a lil gas with it) but when it did i ran the bike for about 100 miles and then looked agaion and they werent perfect but it was cleaner looking.
Seafoam in the oil is fun. People think your car is a POS and burning mad oil(which it technically is) but its making your car cleaner.

With the bike running, you're supposed to just pour a little bit into a vacuum line to clean the intake track. It'll smoke like crazy but it seems to make a difference.
P.S. I used to live in Rancho Sahuarita

No problem on the after pics. I would do the video if I knew which vacuum line to go into. I am going to have to trace it out once I get in there again. I need to make sure I tie into a line that evenly feeds all 4 TB ports.
I didn't go into the oil. The build up is on the bell of the valve so going into the oil wouldn't contact the effected area. Went through the fuel.
SeaFoam has an SOP for going into a vacuum line while the bike is running.
To remove carbon and varnish deposits more quickly, Sea FoamŽ can be induced directly into the combustion chamber via the following method. With the engine warmed up and running, SLOWLY POUR 1/3 to Ŋ can of Sea FoamŽ down the carburetor throat or into any main manifold vacuum line that DISTRIBUTES EVENLY TO ALL CYLINDERS. Note that some newer induction systems, like those found on Vortec and Subaru “H” style engines, do not have any vacuum line that distribute evenly. Consequently, this process should only be attempted by technicians with a comprehensive understanding of the engine’s induction system or use Sea FoamŽ Spray through the throttle body (discribed in a different section of this web site).
Once the product has been applied, turn off the engine and allow the Sea FoamŽ to heat soak for a minimum of 10 minutes. At this time, Sea FoamŽ will dissolve the varnish deposits that hold carbon together. After allowing the Sea FoamŽ to soak, restart the engine in a WELL VENTILATED AREA as exhaust will be extreme for a short time. Drive aggressively for 2 to 5 miles to allow all the atomized carbon to be safely expelled from the system. REPEAT Sea FoamŽ TREATMENT AS NECESSARY
Before attempting this though I think one should consider engine sizes for product amount in application. 1/2 a can is about 8oz and in a 600cc motor compared to a car engine that could be alot. If anyone has any suggestion I'd like to hear them.
Rancho huh? Great neighborhood for kids and singals. I could see a TV show starting there...House Wives of Rancho Sahuarita...
