Greetings fellow riders, Yesterday I was out for a short ride around town when I noticed that when I wrapped on the throttle there was a sound of what I thought was a couple of pebbles hitting my fins, so I assume this is pinging. I had the cylinders cut to .4889 I believe as rocommended by S&S and added the 600 cam 640 springs. It runs really strong but I am not comfortable with this new sound, that being one of a kinda whind from the cam area also . The guy who did the work is 3 hours away but I plan to get back out his way for a checkup as soon as time allows. I did added the spike to the setup so I am not sure if that would have made a difference, but for the sake of giving all the info, I added a pre filter to the crankcase breather hose. I do run the 91 octane in it and compression is 10.5:1 now. But I want to be able to verify that information myself. Thanks for your attention guys in advance. Going to check the plugs now.
