as some of you know i have posted a few times on the pinging.&nbsp\\; it drives me nuts, i ride fairly hard so the pinging is not good.&nbsp\\; anyway, for those with the pinging.&nbsp\\; octane helps greatly and it was how i resolved it until now.&nbsp\\; just put colder 4163 spark plugs with no octane and although i have not had a lot of time with them, they seem to make a huge difference.

 

I just added&nbsp\\;the SE Air, pipes and of course the all important download, running on&nbsp\\;91 octane&nbsp\\;and have done about 300 mile on this set up. This reduced my pinging dramatically, to almost non-existant. I might try your suggestion&nbsp\\;and see if it can't be totally eliminated...

 

SOUNDS SIMPLE&nbsp\\; why didn't stealer suggest that???

 

What did you use to increase you octane?

 

I used lucas octane booster on cross country trip.It help a tone with that lil sob beating the top of my new pistons.I think his arm get bigger as the trip went on or hi hammer bigger,I had few fill ups w/o the booster.

 

You should not need octane boost in a low compression engine
to avoid ping.
In fact there is a lot of literature that shows 89 is fine.
It detonates at a lower flash point.
I would look at the fuel managment system.
At what rpm is it pinging...????

keep the rpm's in the 2300 to 2800 range for zero pinging.

 

If you put a gear reduction kit in, you can run 85 octane and never have a problem
and then pull the house down
