Bike pinging

I put the stock ignition back in and it will ping if I'm not above 35-3800 rpm... and I don't go WOT unless I'm in the upper 3k in RPM's.
You're welcome, cdogg. Notice BW's statement--in the paraphrase... 'No matter what I did with the timing, I'd ping at any degree until I hit over 3k, then I could rip it up.'

Take it for WOT it's worth. I believe this She'weetie you have, has her own idiosyncratic way, is to sneak up to the throttle apply. Find where she is quiet as a mouse and you found her G-spot, I mean, sweet spot. Same goes with throttle apply in the low rpm range, meaning, no need to mess with the accel pump, more like, find where slow opening too soon is when? Look at the speed, listen for the revs, know which gear? Find that low rpm idio.

Just so the guess pans out, and to make sure there is no ignition problem per say, the guess is all about heat. So the plan is to take a ride in the cold morning and try the same throttling you are doing now; see if it pings? None to hardly notice is your ignition is cleared no prob, and the fuel delivery is not like sun is straight up, most heat of the day is coming and it should say; nothing mechanical in fuel delivery; nor is it an ignition on the blink; when no ping is present being that cool out. Make sense?

Ok, got it, basically find out at what RPM I can hit WOT without pinging! Find the "sweet spot" Lol!

What spark plugs are you using? Also, how hot is your motor getting? Also, if your engine is running too lean, or not consuming enough fuel for the amount of air being burned, this can also cause engine pinging.

Adjust the air to fuel ratio, either cutting down on the amount of air allowed into the engine or increasing the amount of fuel being burned, make sure you have the right plugs and get a temp gauge.

Here's the plugs after riding, the left is the rear cylinder and the right the front, they look pretty good to me, maybe slightly lean, so I increased the fuel intake and did't notice to much difference, if I roll the trottle on up to 3800 rpm and then nail go WOT, it barely pings!

SVEN???


These porcelain tips means nothing.... we need to see a little bit more into the plug.... also... wrong angle.... lets as see the curve of the top "electrode" (or mass)... there is where you can read (see) if the timing is right. It should be right on top of the 90* angle.

BTW... mine are alot whiter.... but nice & grey a little bit further inside....

BTW............. Sven, who´s Sven? many of you have been asking this very same question for a looong time....

Well, let me tell you something; Sven is a fucking good Mechanic... I have been following his responses to all the threads in here and......... it really makes sense (and it does work!) I know, I know......... but Hey! nothing is easy....... imagine me... English is not my mother tongue... but I did take the time to understand what hes saying..... Sven is an awesome mechanic who knows his shit!!!

Thanks Bro. keep it going, it works for me!

Tried this octane booster last night and what a difference! No pinging and the bike runs and sounds totally different!

Looks faster now just sitting there! Lol!

Yea, I know, your video of the bike idling in the garage a few months ago tells it all, that fucking bike sounds bad ass franco!
That's what I want mine to sound like, if it runs as well as it sounds then I know it will be worth it!
