I couldn't get link to work. I think the system may be very good, but I can not get a straight answer from anyone other than, well it makes mine runs good, heck my V&H fuelpack made mine run great, cost a whopping 189.00. I just think some facts would be nice, the thundermax company should be flooding us with test data to convince us.

 

My 07 RK has never pinged. I had to run some 87 octane in it to get to the next town and I still cound'nt make it ping.

 

211Chuck: Keep us posted on this product. Will be interesting to see how it performs. As for me, I will have to wait until the price comes wayyyyyy down. LOL

Ride safe,

 

hey gunrunner ,thanks ,I'm glad its not only me who knows they are full of sh....,its just a little anoying the fact that a brand freakin new bike sounds like it is going to expolde.. I did talk too probably the most honest of all harley techs a couple of weeks ago,an old timer in Myrtle Beach ,though he did not admit too a specific problem ,he told me that ever since people started stroking the ole v-twin there has always been a problem with pinging ,though on a bike with a carb its pretty easy to overcome .what really sucks is I have since found out that stroked motors dont last near as long as a typical engine ...............those bastards......,well anyway after my 1500 mile ride between Myrtle beach and the two coasts of Fla with Skynyrd cranking on that pretty damn cool radio system ,I do believe they have some piston work to do on mine.good thing for the warranty guess that $25,000 I spent has to be worth something.

 

Not sure it's allowed to give other sites addresses out here so I won't.
There is a very informative thread, actually several, on another very large forum. Some of you are members there. I don't have a Thundermax but sure am thinking of one. (PC111 now which I like).

 

Good Luck! My '06 pings and HD could care less. Oh, I forgot, it is NOT a ping, per HD it is a "low load rattle" caused by the lean condition they must run to meet EPA requirements......

Of course the HD Master Tech that road the bike when I first took it in for the ping (and each of the follow-up visits) agreed that the noise is a PING!

 

just my .02 here.
But before you go spend a lot of money I'd say try this first if you haven't already.

Valve train noise get a mechanics stethoscope (or a very long screwdriver will work)
listen to the engine while parked at idle and other rpms. Put the 'scope down on the
cams and pushrod lifter blocks and move up to the rocker box, to try and locate the area noise is coming from and when (hot cold low high rpms).
Normally lifters / valve train will be noisy when cold (first startup) not warmed up.
As all the metal in the train expands and makes tolerances tighter. so even though this may help find where it is at, may not resolve the actual cause.
Pinging and wrist pin two different problems and sounds.
wrist pin is more of a knock (like a bad rod bearing) but is usually noticeable AFTER the spark as the explosion crashes piston down on the pin. rythmn changes with rpms as you rev up and down engine.
detonation /ping happens because the fuel /air mixture ignites from heat and compression just before the spark fires.
Advanced timing and too lean mixture will cause this.
HDMOCO has issued a voluntary service correction issue on this for some bikes.
They remap the ECM to adjust timing and air fuel to modify the torgue mapping.
this supposedly helps cool down the heat issue( a cause of pinging).
Severe detonation can ruin the piston, and because of the unintended out of time firing, can cause cylinder pressures high enough to rattle a valve that is off it's seat thus contributing to the valvetrain clatter.
So first I would go to dealer and besure the injectors are the new upgraded 06a 25 degree
and try and get the free remapping under the 0903 bulletin.
Also get it in on a work order and have their tech do whatever so it's documented.
After you've done that call HDMOCO csr and file a complaint and get a reference number so HD can track this issue and maybe come up with a favorable resolution.
After you've done this and you're ready to spend YOUR money, then look into the aircleaner, mufflers, sert or pc iii etc. most everybody else here has recommended.

 

Put on the SE Race Tuner and have it dyno'd, your bike is lean due to EPA. Riching it up will most likely cure your problem. It will also help it not run to hot in the summer. If you plan on exhaust or aircleaner changes, do that first before dynoing.

 

havnt been on my bike since Nov,,, but it Pings, Clancks, chatters,whines,and is HOTTT
other than that its fine,,,,????!!!!
was gonna get PC111,,, but dont think so now???
anyone looking for a Ultra,,,, I'll trade ya for a huge roll of toilet paper!!! lol

 

Yes! You have just discribed my '06.

Two trips to a dyno-tuner to get PC III and dyno-tune ---- and with the PC III and tune, the ping is much worse.

Without the PC III, the bikepings when at normal temp (210degrees oil temp or above), when going up a hill in 4th or 5th, from 2,200 RPM to 2,900 RPM,andI roll on the throttle. It only pings a few times, then I believe the ion detectors adjust the timing and the ping stops. I figure it should not ping at all unless I put low octane gas in it.

With the PC III, the bike pings in any gear with throttle roll-on, and pings above 3,000 RPM on level road with throttle roll-on.

The PC III is resting comfortably on my garage shelf. Took it out before it screwed up the engine.

May have another go at dyno-tuning but must wait until it warms up. The bike does not pingas long as the temps stay below 60 degrees. It is only in the summer (like when you want to ride the SOB) that it gets hot and pings.

I will never buy another new Harley. If I can sell this POS, I hope to find an early model, carb,TC88. Like '02 or earlier --- before Harley improved the engine by going from two main bearings on the drive side to one main bearing....... A bagger that came stockwith thechrome passenger grab rail - before the grab rail was a $128 add-on. Etc. Etc. A bagger that you can ride in the summer without actually burning your legs. I've been riding over 40 years and this is my 6th HD ---I loved the others--- but this one is truly a POS.
