Hello everyone,

I’m still having some issues with timing my 98 1200s and pinging under load and I was wondering if anyone could give me any further insight.

Here’s my setup:
1998 HD 1200S
Accel 2418 copper core spark plugs (too hot?), gapped .26 per Dynatek’s recommendation
Mikuni HSR42
- 165 Main
- 25 Pilot
- 97 Needle/middle position (could be too lean?)
High flow air intake
Hammer Performance machined intake manifold
Dyna 2000i nosecone ignition module
Dynatek DC6-4 coil, for dual head plug applications
Supertrapp 2:1 with 20 discs (10 discs + open end cap)
VOES w/ 6” mercury
Running 93 octane gas

Here is my issue:
I’ve timed the bike at first TDC on curve 4 with about .030” retarded timing. Bike was pinging under load.

Then I retimed the bike TDC on curve 4, but fully retarded the timing as much as possible (cranked fully counter clockwise) per Hammer Performance’s advice (dual plugs want way less engine advance, the pinging seems to be a common issue with a similar setup as mine.)

This seemed to help a bit, but when I get up into 3rd gear and lay on the throttle I still get some pinging.

So then I retimed the bike 4 or 5 degrees before TDC, on curve 4, fully retarded the timing as much as I could via the nosecone- STILL pings under load in 3rd gear.

So my ignition timing is retarded as much as I absolutely can with this module without getting the custom harness to program a curve.

My theories:
- Spark plugs I’m using are too hot / don’t match the stock HD 32362-04 heat range (6R12).. haven’t been able to figure this out yet or if it would help.
- Carb is running too lean from the pilot jet, lean condition is causing pinging. Haven’t tied switching needle jet positions to run more rich or switching for a richer needle yet.
- Air intake leak somewhere, still have to test but highly doubt it as all the gaskets are new and everything is torqued to spec.
- My worst fear, the ignition timing / curve, even 4 or 5 degrees before TDC + fully retarded on the nosecone, is causing the pinging. I would have to wire in the programming harness or per Hammer Performance’s suggestion, just buy a new coil and only run 2 plugs which should solve the issue. Both are gonna cost more time/money.

I’ll also include a picture of my spark plug because it does look to be running lean, but I’m very new to HD and these bikes- just dove into it head first over the winter and trying to figure shit out. Any advice or suggestions you can give would be greatly appreciated. Thanks again for your time!

Under load and in low rpm its notmal squiking and clicking pinging like ,that happened tyo me but i try not to full throttle while riding heavy person uphil in low rpm.

HI guys ,i have Dyna 2000i ignition and it seams that stock XLH1200S was better than my tuning now. What do you all think?

There's a guy who goes by Stevo on the forum. He seems to think the S model supervisor to aftermarket ignitions because it based off a MAP sensor that selects from 9 different curves programmed in the module. (I was told 9 different maps, not sure if it's true). Also since it's based off a MAP sensor the S has a 3D advance curve. (So it's been said on the forum). Stevo has run the SE ignition (for sport models) on 1250- 88inch buillds with no issues. When you go to an after market ignition, you can only run two curves due to the VOES which is basically an on off switch that chooses between two curves.
I feel that the S model is superior to the aftermarket options for our bikes.
I hope this gives some clarity.

there is +/-'s to each.
a map alters voltage with vacuum levels and this diff'l is sent to the ecu. there is not separate curves, only one. the ecu uses the input from the map sensor and alters the base curve to suit load. that means riding same conditions solo and two up can and probably will have diff adv timing.
i run the ultima system without voes, basically operates like the old mechanical system and no issues, have to do this because the voes will always force as much adv as it can which gave me clutch off issues which could not be tuned out.
it was better than the map ign because it took out a lot of timing in the upper rpm range just like the voes. this is fine for a stocker sunday school rider.
i still have the old system with several modules that are plug and play. in case the ultima goes south which happened already.

Im on the fence about purchasing the daytona twin tec ignition. I will be installing the SE CNC heads with matching pistons and .575 cams. Its been mentioned on this forum that almost all factory ignitions have too aggressive of a curve for engines with higher compression. I am assuming this is the case with the SE 7500 module as well. Even if I were to dial back the timing at the nose cone the curve(s) programmed into the module are still too aggressive and can lead to damage and/or piston scuffing. If I were to go to the daytona twin tec setup my components will be up for sale. I have two spare 7500 modules and two SE coils. Plus the ones on the bike. Also I still have the stock coils and modules.
It appears that that Daytona has and external module set up 1007EX. Has anyone tried this? Any input and guidance on the ignition system would be greatly appreciated.
