Hi All,
As I'm going in for my second valve inspection 2009 (56K), everything was very dirty etc., so I removed the whole exhaust system to go in for a deep cleanse.
I now notice that on cylinders 1,3, & 4 that on one side of the exhaust port, half is clean and half is black with carbon. I'm baffled and would like to know if anyone has seen this or can explain what might be going on. no exhaust valves are out of spec. the spark plugs all look the same nice and clean tan color. bike was running well with Steve's Mountain runner premium flash. Any insight would be greatly appreciated.
Thanks,
Richard
