The pinging can be caused by a lean fuel condition, as another poster said, "you are ruining your engine". There is no oil additive that can remedy your problem.

Mine was makin a similar racket when lugging the engine and I looked into it and my stock compensator was loose. I retorqued it to spec and it was about 50% better.....I wasnt happy with that so I ditched the OEM compensator with the much improved Screamin Eagle Unit with updated chain tensioner and it sounds great!! All of the primary noise is gone...

The valvetrain on Twincams is a tad noisy. So thats no issue if thats what it is. Now detonation or "pinging" takes a good ear to hear and is detrimental to the pistons. However if your engine is stock the compression is extremely low (9:1) or close to it and it should not have any problem on premium fuel.

So, I think you are hearing the valvetrain noise, and possibly have a loose compensator bolt...I say retorque your compensator bolt and change the engine oil. Add the Lucas stabilizer (20oz) as recomended at this time.

Maybe consider getting a tach for your bike would help...I have a Speedway mini digital tach that works just fine for 149.00. I use the tach more than I look at the speedometer.

IMO, the TC motor likes to spin a bit...mine runs much smoother at 2600-3000 than chuggin' along at 2200 rpms. Try runnin' at 45 mph in 3rd gear, which is 2800 rpm or 55 mph in 4th gear...also 2800 rpm and see if it feels smoother than runnin' at 50 mph in 5th. :icon_idea1:

:icon_that: Good advice. Get a feel for how she sounds and feels at the speeds and gears he mentioned. Once you do it will become second nature.

I love my Dakota, lot's of fun stuff on it like a 0-60, 1/4 mile, and other useful info.

Just as a comparisson: I rode a EVO powered sporty for years, and it did the same thing, especially in hotter weather. Was told by a mechanic friend to keep the RPMS up...and it worked. No more ping. When I bought my TC Dyna, and it did it too, that just verified everything ive been told. As the other posters have said...just teach yourself to run a little higher RPM and all will be good. A tach is good to have, but not necessary (unless you are racing...then it is a necessity!)

^^^ I Agree! I've noticed that my bike runs much smoother at these higher RPMs. It seems that the transmission and the engine pair very well together in this range. My bike has a slight ticking as well but I recently switched to SYN3 and changed out my rocker covers. I had my dealer take it out for a test ride and the tech came back and said everything sounds normal . . . so I'm learning to live with it.

You newbies make me laugh, :icon_laugh: throwing money at your bike, instead of reading your owners manual and learning how to ride your bike properly. RTFM! It tells you when to shift (using your speedo). And just listening to your motor should give you a small clue. LOL!

Dude, lighten up, I suppose you were a master with your first bike? No need to beat it to death.
