2021 s4 b9.5 has 68,xxx miles. Started hearing this noise issue like a week or 2 ago. Car is tuned by jackle but I haven’t noticed any performance issues. I know the car is loud and chatty but seem excessive from the wheel well. Also I know I will flag a TD1 from the dealer. Should I clone a ECU and send it in or should I buy 3rd party warranty and de tune for this? Please don’t confirm my fear of piston slap
I have a Gsxr 750 2008. 22,xxx miles. The past week the bike had developed an odd start up. Only when cold, I start up the bike and it bogs down as if there is a fuel issue or something and it will die but I also hear a loud almost rod knock sound. Now I know it’s not rods as when you give it a little gas before it dies it goes and ideas like normal and all is well. Shifts great, great power band 1-6th gears no issues at all only at start up. I’m thinking it’s a timing chain tensioner but before I buy the part I’d like to make sure. The bike in this clip was slightly warm after a ride 4 hours ago where I beat on it and road it like it should be. Please advise as I don’t want to hurt the bike but after it’s started I have absolutely 0 issues. Did a fresh oil change 800 miles ago and all fresh spark plugs as well. I have not done coolant and unknown if valves have been checked.
