It raises compression which causes deto. Also my Gramps drove bike had so much that it starts to make pistons hit heads with the hard build up on the front and back of these bath tub heads.

 

=====================

Techron dosent remove all or most of the carton buildup like other same type cleaners you simply add to the fuel tank on the market too.

But what i found techron in the " concentrated version " does in cases of excessive carbon build up that may be causing detonation is it " effectively reduces carbon buildup in comb chambers " enough to help reduce or stop the detonation along with also do s good job cleaning on backside of intake valves valves & injectors too.

I have a bore scope and have actually checked backside of intake valves (thru intake) and comb chambers (thru sparkplug hole) pre & post cleaning using techron so i know it works when you do what i do.

Here are reasons i found some people(Maybe you) have not had as good a results i have when using it.

1) Chevron mfg's 2 versions of Techron ,1 with std cleaning power and a 2nd states in the CONCENTRATED VERSION on the label so when i post i get good results its always with concentrated version where as you or other people may have used the weaker std non concentrated version that dosent clean as well.

2) When i post i get good results using Techron in concentrated version i also state to use what i term a HEALTHY DOSE of concentrated Techron of 1.5oz per gal of pump fuel vs the mf'g rec dose of 1oz per gal which is weak & somewhat ineffective from my 1st hand exp.

And 2 times i also rec running a couple full tanks of concentrated techron at the higher 1.5oz dose per gal fuel treat rate thru the motor too.

So either of the above issues by themselves can cause a poor result using techron let alone if someone had both the above issues going on when using techron .

With that said over the yrs i have tried just many of the inj/carbon cleaners on the market that you add to the fuel tank & even at higher then the mfg's rec dose they dont seem to work as well as concentrated techron (applied/used as i rec above) which is why i end up back with techron's (" concentrated version") @ the more robust / stronger 1.5oz per gal pump fuel dose.

I also get great results using concentrated techron in my every day use vehicles/cars with EFI too.

Seafoam is my 2nd go to carbon/injector/carb cleaning product that i have also found to be a decent product too.

Happy motoring.

This is a very accurate post. I have used Techron Concentrate only for years with excellant results. I have also "scoped" 2 of my TC's and the valve stems are clean also top of pistons. I have used this product several times after ping starts and it's gone before treated tank is used. This stuff DOES work.

 

As suggested, I would start with fresh plugs, check or replace your wires. If it still pings, I would look at timing the ignition or go with a new ignition module. The carb could also be jetted incorrectly.

 

Having a "thermal" layer on the pistons it beyond idiotic. First that would defeat the oil mist H-D sprays on the underside of the piston to cool it.

Secondly carbon heats up and glows red hot in spots which is what causes most knocking by causing spontaneous combustion.

 

I guess you've never heard of thermal barrier coatings...

Please explain the mechanism where a thermal barrier of any type on the top of the piston effects the bottom..

I thought the problem with hot spots was preignition... Ever hear of "boundary layer"?

Google up spontaneous combustion..

You might learn something..
