I installed the TB cam on my 2015 OG a couple weeks ago and at high RPMs the motor don't sound right to me.. Valves making a slight noise as the RPMs increase. Not noticeable at idle.
At first I went with the recommended I.004 & E.007 valve clearance.. That didn't sound right so I called Hard Racing and they said to try I.004 & E.006.
This sounded better but I can still hear the cam/valves tapping at high RPMs... Its like I can hear the cam spinning and hitting the rockers... Has anyone else experienced this? I have checked the clearances after a few days of riding and they have not changed..
What valve clearance settings have worked for you guys?
Also do I need to (or should I) get stiffer valve springs to accommodate the steeper cam slope?
