Bike pinging

[cdogg556]

My bike has been pinging just a little not really bad but enough to be irritating, so I have read about a few different ways to go about fixing it, one is running higher octane fuel, all I can find around here is 91 octane, I could mix some racing fuel in it but it seems from what I read that it's not a good idea to do that, also I am assuming that a larger main jet might help, or I have read that Curtis installed a programable ignition and that did it, so I just thought I'd get some opinions on what is the best way to go!
See Ker you were wrong, it wasn't my tire splitting that was next! Lol!

This isin't a problem, its driver error

Get some real gas, 93 is what we have here, buy some octane booster. The other question would be, are you lugging it? drop a gear before you start to accelerate to get the RPM's above 3000.
Yes there is a programmable ignition from Thunder Heart that is plug n play for our bikes, some say it makes a big difference, I personally didn't think it did anything. You can change the settings for a different timing, 28,30,32,34 advance timing. Stock I believe is 32. But the way I understood it, the factory will adjust for knock and engine temp and the TH will not, so choose your poison.

OMG! That's what your suposed to do? I thought the right grip was just for holding on, your actually supposed to twist it?

Ker, I don't know what I'd do if I didn't have you around to straiten me out! Lol!

I read that octane booster eats the lining in our tanks, any particular type better than another?

Yes, dick head, I read that post!

Go to J&P cycle on line. Look up rocket fuel. These are small packs of Octaine booste. I keep 5-6 in my Tee bag. If I buy fuel out on the road I simply put 3/4 of a pack in there & toss the rest in the trash. I checked this 2-3 times with an Octaine test and using super unleaded & 3/4 Octaine Booste pack I get 98octaine. Normally I fuel up at my house or top off when I get back with 100% Octaine AV gas!

Thanks Jonathan, I am gonna check it out right now!

The methanol eats the tank liner also, when I had my tank fixed the guy said it came out like a big snake skin and pieces of it were all over the fuel shut off when I removed it. I'm trying to help and your getting all up in my grill, maybe a little smack up aside the head will straighten you out

and what's up with Jonathan gettin Tea Bagged

 

[BadDawg Bill]

Your timing is too far advanced... Forget about the fuel.

Haha who knows your guess is as good as mine

Bill, I don't think John has a programmable ignition yet, so how would you retard stock set up?

[some] Race gases eat more than liners. It decomposes and clogs up jets. So sad was me watching the race bike run 18a {really lean] in ratio. I mentioned something to the effect of I do not like what I see on the dyno. We go out and shake it down on the track... I see it smoking coming in and that did not look good. Rider mentions he heard something. Never did I see aluminum skirt damage backwash right back out to the velocity stacks, no shit! Number 4 cyl was not that bad a shape, nor was the jet that clogged if I recollect?

Summer days and think Heat expands inside the chamber, will lean out the mix. Do we:
a. Step up the accel pump for a few months of hot days?
b. Accel in a more slower throttle opening?
c. Rejet for hot days?
d. Retard ign and run an even hotter engine or advance and detonate at peak TDC compression?

Alex, I'll take, granny grab my throttle opening for 400 less pre-ignitionslow as it goes.

So basically Sven is saying back off on the throttle, right?

Yes, in case you didn't understand, that's -b open it slower not backoff retard

That's funny you Wanker!

 

[cdogg556]

Ok, seriously, what should I do? It's not super bad but it is irritating! Is the only way to retard the timing is by installing a programable ignition? And are you sure that octane booster that Jonathan uses would eat the liner? It seems like really good stuff, made for big twins!

Ok Johnny, listen up, when I installed the 585 cam, I also installed the TH programmable ignition. I had it set at 32 advance and if I would go WOT it would ping, changed it to 30 advance and it pinged, changed it to 28 and it pinged, no reason to go to 34 advance. And I'm running 93 octane, I put the stock ignition back in and it will ping if I'm not above 35-3800 rpm when I go WOT. Thats my experience with a programmable TH. Most of my riding is with my wife on the back and I don't go WOT unless I'm in the upper 3k in RPM's.
Now on the other hand the 585 woke this bike up like no other, it freakin rips around 4k n up thru the gears.

Carb wise, more accel pump. Why? Cools the lean-HOT chamber. When does ping happen? Most likely at peak kinetic or when all is compressed and can't reach any peak higher than TDC (top dead center) is ping-det, not pre-ignition. Pre is when there is a glow plug effect as in, carbon is glowing cherry red, then here is the igniter, not the timed spark plug spark and you meet two flame fronts and hear that bang. My guess is too lean, compress what little air is there and boom = ping.

Right on Sven! now that I understand,
