Hey guys...I no this subject has probably been beaten to death, but is it O.K to change over to a synthetic oil at 300 miles, which is where Im at on my 04 1k. I waited untill 1500 miles on my other two bikes, but I thought I should do an oil change early to get all the crap out of there before the 600 mile service. I have three quarts of Mobile 1 15w/50 sitting around and thought about using them before my next ride this weekend. Should I use the oil or just wait for the 600 mile service. Thanks for any input.
