Hello,

Since putting on my D&D on the 2005 City X, my bike wants to ping at lower RPM's. I ran 110 leaded mixed with regular premium Shell for a couple of tanks and it never pinged with that. Now running straight Shell premium, and ping is back. I am looking to get some sensor safe octane boost to keep around. Can you guys recommend any you like? I can't run the leaded fuel for fear of screwing up my sensor.

look for something OTHER than the octane rating. It seems to me, as I have the same problem as you, that there are some other things happening. It's kinda like turning up the radio to mask the exhaust leak in your Duece and a Quarter.

Kybueller.... This did the trick for me. Just retard the timing.
Edit: So .. I click the link I just posted for you, guess who just posted there... doh!

kybueller,
I noticed you posted on the "pinging, please elaborate" thread linked below. Have you tried changing your timing and still have pinging problems with pump fuel?

Has anyone heard from "Glitch" lately?

Has anyone heard from "Glitch" lately?
Rumor has it he's been very busy lately.
Thanks for the e-mail Davo.
I've found that setting the timing, using the Davo, non-Factory supported, timing method worked for me very well.
I've also found that (I was warned by Davo by the way) one must be very careful while adjusting, a little goes a long way.
Instead of re-writing my response to Dave, I'll just paste my e-mail here.
I'd like to see some thoughts and comments on Heat Soak, from those that know.
Dave,
I've been really happy with my adjustments.
I only had to re-visit once.
I seem to have gone a little bit too far with regards to turning back the timing, so I just started over and tried to get it spot on, with great results.
I've ridden to work a few times, and in the mountains a bunch with no pinging issues.
The only issue I have at the moment are wear issues.
At 46 thousand plus miles, it's time for a new front rotor, if I can pull it off I'm going to buy the 8 piston caliper, now that the Buell Race parts are now available.
Also last weekend while in the north Georgia mountains, my right side fork seal started leaking. $54 to re-build both forks!
Oops! I got off the subject!
I read an article, I can't seem to find right now, I hope I can find it again.
It's about Heat Soak.
Heat Soak is when the engine gets hot through out the engine.
Engine tuners seem to be the most concerned.
Turns out that while on the dyno, the tuner has to be careful not to let the engine get Heat Soaked, because the bike starts to lose power, and tuning gets more difficult if not impossible.
I was wondering if that's more the problem, with some of what we're seeing on the BadWeB.
If the bike is pinging at a certain RPM, regardless of gear, or load, that seems to me a timing issue.
If the bike is in traffic, and it pings while accelerating, I think that may be the Heat Soak issue.
I think I may have had a mix of the two, because it was pinging at 4000RPM no matter what, and if I was in the heat of the day in traffic, it made matters much worse, and the pinging was most all the time, until the bike was moving again (getting air moving around the engine) then it would only ping at 4000RPM once again.
What do you think?
Thanks again for your hep with setting the timing, it is priceless.
I'll post on the board, with the hopes of helping, and not confusing!
Maybe someone with tuning experience will chime in about Heat Soak, just in case I can't find the article.
Dave

I have not tried retarding the timing. I guess that would be a good project for this Fall. It never did this until I put the D&D on it? It almost never pinged with the Buell factory race pipe on it...who knows. Why would a different pipe suddenly cause it to ping more? I'll try the timing adjustment. Thanks everyone.

Of course the D&D would cause a greater chance of pinging, as it is freer flowing exhoust then the race pipe, thus it can be causing a leaner running condition, adding excess heat to an allready hot engine, anding to the pinging problem, to a point.

The timing adjustment worked for me. It still pings at 95+ degrees ambient, but not too bad. It used to ping even in cooler temps, now it is well behaved.

The timing adjustment as per Davo took me only a couple hours, and although I like to think I'm handy, I'm no mechanic and I like to go slow and careful with such things. I also switched the rivets to threaded since I didn't want to mess with a rivet tool.

My timing is now very slightly retarded. When it is really hot I have used STP octane boost with Jet Fuel (says safe for O2 sensor) as well as a couple other kinds. Check any auto-parts store for an octane boost that says it is safe for O2 sensors and you'll be fine. I use more than the recommended amount (like double).
