Head buildup???
I've got an 09 RK with about 5500 miles. For the last year I've been running a K&N intake similar to the HD Heavy breather.
Recently I removed said intake to install a new SE AC.....got bored with the K&N. When I removed the breather bolts they were caked with something that resembled gritty sludge.....kind of like soupy coffee grounds. I've never seen anything like that before in any of my bikes.
I change the oil at regular intervals, and have used Royal Purple Syn since the first oil change @ 1000 miles.
Now, It could be normal since the K&N intake uses the breather tube, and since i've never used that type of intake before I don't know.
So......should I be concerned? I bought a can of Seafoam but I'm not sure if I should use it in the tank to clean the fuel system or put it in the crankcase and change the oil.
The bike has a full stage I, slip-ons, AC, and tune but it does seem a little sluggish power wise.....but that could just be my imagination after seeing the crap come out of the heads
Any thoughts of suggestions are welcome and appreciated.
