cctl or bent valves video
Read up, but not sold on what it is. About to tear apart motor to confirm but would like some direction.
It is 22,000, tuned, ran great, and had newish oil, about 500 miles. Plugs are about 15k old though id say.
I replaced the CCTL with a new OEM unit about 4-500 miles ago.
I had thought I had a slipping clutch due to some power loss feeling around 4-6k. It then suddenly made the loud rapping metal to metal noise. mostly right side it seems. The exhaust still sounds like all 4 are firing. While I rode it home, I noticed the power loss in those RPMs was dramatic, but came back to more power after those RPMS, still rode soft to not kill it on way home.
So far I am going to pull plugs, pull old CCTL and try putting in the old one that was not necessarily bad. See what happens. Is there a way to check timing without valve cover off?
high quality video, sorry big.

gold/brass colored flakes are typically bearing material... Could be from a multitude of things though since the fluid is shared in the crankcase, transmission, clutch, etc.... if your having problems with your Cam chain tensioner i would check it very good and see if the shavings possibly came from it
