Re: [ST] Several questions



Is everyone staying current with their maps?  I'm thinking about this more and more, and I have never experienced this.  I have had both a 2000 and a 2001 ST (so experience with two of the bikes); I've run the bikes with stock exhausts, Triumph Off-Road, and third-party (PowerMax); had a K&N air filter in one of them; I've run the bikes to sea-level (back and forth to the beach for a couple of summers every weekend; run the bikes up to the highest point in the Blue Ridge Mountains, up through the mountains of up-state NY and Vermont; I've run nothing but 89 Octane; run the bike loaded down with my fat-ass and three bags full, and a bag behind me on the seat; and I ride the bike hard (including track time).  Just seems weird to me.  I do know that I make sure that I stay on top of the tunes as Triumph are constantly tweaking them.  But I've never run into this.
 
This is not really any answer, but it just has me wondering....

Ping is really pre-detonation.  The fuel/air mixture is being ignited before the piston reaches TDC.  Therefore you have the ignited gases pushing down while the piston is still moving up.

Hmmmm.  Having said that.  If fuel isn't your problem, maybe it's timing?

So, let's remove the fuel from the equation:

What else could cause pinging?  Hot spots (carbon build-up) removed by fuel
system cleaner.

Anything else?  I will go up to "premium" fuel and try that.  But if it
doesn't fix it I'd like to know what else I need to look at.
