dJames Posted May 24, 2011 Share Posted May 24, 2011 Went for a run this weekend on the 04 1150 RT and after a few hours of riding it started making what sounded to a metallic knocking noise, almost like a jack hammer hitting something metal (just not quite that loud). I only heard it in 6th gear and made the noise at all RPM's. I cannot hear it at idle. I did my first valve adjustment around 1k miles ago. I did not use a torque wrench on the adjusters, (could not find one that would work properly, most were way too big). I also have been running 89 octane and has been running fine with it for last 1k also, but will try 91 though I do not think it will make a difference as it does not sound like pinging. Thanks for the help. Dennis Link to comment
