Random Stall – a Silver Bullett or as close as we may get. TR650 Husky

During a heated 120k ride, the TR started surging, heres the result
A couple of pics of a pulstar plug failure after 8000k's.
View attachment 72900View attachment 72901
Half of the electrode pulled out
As you can see the crush washer and thread are clean, and the plug wasn't lose. So I dont know how coil boot melted?
The gap to the ground has increased a lot and I suspect this is because the plugs are not in the correct heat range.
Buyer beware

I'm curious as to how you had the grommet at the top configured to make up the added length of the Pulstar over stock. Did that have something to do with the failure?

Edit, I see you have the O ring added. How did that secure the coil?

Mag00, the same thought here, remember the pics in another thread re the failure of from memory a Brisk plug ?, gap was opened and it was clear there had been an internal failure in the plug, the thought of vibration failure came to mind on it, could even have been a manufacturing defect on both causing high resistance and resultant heat build up internal to the plug due power being dissipated internal to the plug, classic electrical failure symptoms

Magoo, dont know exactly what you mean by grommet at the top. I used a 5mm and a 6mm o-ring to secure and support the coil. And made certain the coil was a snug fit to prevent fatigue, but it is still possible I guess.
I took the plugs out at about 5000 klicks and found the gap had grown to 3mm. Which leeds to believe they cannot cope with the hi-comp heat. Regapping and reinstalling them.
And to be honest I couldn't notice any difference then and now back to the standard issue also. To my way of thinking "that's why we have two plugs".

Wayne I did a autoscan after that ride and found 3 errors. Do you know if they are coil related? The hexcode web site isnt much help with errors.
I do a autoscan every 4 or 5 weeks and these are the first errors. Once cleared they have not represented after two days of commuting.
And I have not contacted Hiclone, dont see any point


Anyhow No harm done
It still goes like a rocket!
Thanks for the input
Regards

As I noted in another thread, when I removed the Pulstars recently I found that the gap on one of the plugs had also opened right up.

Just wondering if you're running the 0280158124 261 g/min Bosch injector in conjunction with the Pulstars?

Thats a no from me, but I am thinking of buying a 124 and installing with a valve job. Why do you ask?

No biggie. Just thought the dual cone spray pattern of the 124 might be creating uneven combustion & hotspots.

The error codes show that there was a failure of comms on the CAN BUS so the BMSE did not see the Dash (Kombi) and hence did not receive the speed signal when it expected it, since there is no indication of how many times it occured and it is not present now you would have to assume it was a one off problem, I have seen the same error on another machine, cant recall which one though

Re the plug failure

If you look at the pics of the plug you will see that the problem is not heat range related, or combustion related, there has been a connection failure internal to the plug and that excessive heat has been generated further up the length of the plug at the point of the connection failure and the upper part of the plug has separated, the centre electrode has retracted slightly increasing the gap but the tip shows no sign of overheat, look closely at the plug tip

The internal connection which is the source of the problem could be either a manufacturing defect or vibration related, the good news is that the tip and the connection up to the failure point remained intact and in place

It is important to let HiCloneQld know re the fault in the plug as it may be production related

It is also worth going back and looking at the failure of the Brisk plug on page 10 of the show us your plug thread

 

[CarstenB]

HiClone has a generous warranty on the plugs so the least you should try is get your money back or new plugs.

Thank you and I will let HiClone know

Re the plug failure

On closer inspection it appears the ceramic came away from the base, causing the melt down of the boot and separation of the top electrode. And does not appear to be fatigued.
Been riding over 45 years and never had an issue with a plug, so you'll understand if I back away. Dont want a new plug, dont want my money back, just rather live and learn.
Might put it on the band saw and see whats inside

Just tried to buy some Pulstar JE2RT8 plugs from Australia and got told " They are unavailable as they are being redesigned or so I'm told". Does anyone know of some anywhere?.

you can have mine that did not fail and if PaulC still has his that did not fail you're good to go I just wouldn't risk it especially since the Pulstars did not make any difference in my Terra over the stock plugs. That re-design phase is lasting for quite a while now and i doubt we'll ever see new and improved ones.

 

[sussurf]

i got the last 2 in Australia few months ago.
I put the first set in at 20,000k and still have them in there currently at 50,000k.
They made a nice improvement to my already nicely running bike back then.

mine have done about 15k and the center electrode has reduced in height significantly, how are yours looking?

Hey Mike, if you are "dead set" on getting these plugs, you can buy direct from pulstar in the states.
But it might be worth asking Louis Camilli for an update on the redesign of these plugs. IMHO You dont want to be buying Gen 1.
He seems like a good bloke and replied to emails, although I agree with CarstenB. I know of 3 failures. 2 were purchased in Oz and I imported mine so it wasnt a batch issue.

I have tried several times to call and speak with a person, no luck. I did read on their website that CEO Joseph Gonella has retired as of 1/7/16 - Here is a number for international calls 1-505-842-5201

 

[johnsweet]

I just had a reply from Lou by email. They said it is being superseded by a (SE2HT) and will be available this fall. His email is lcamilli@pulstar.com
