No eBay APP ID and/or Cert ID defined in Kunena configurationHave anyone of you tried this piston set? Seems to be the cruizinimage 150 usd cast piston set but with special coating done to the dome, skirt and wrist pins.



"Piston domes are coated with CBC1* thermal barrier and skirts with DFL1* high pressure dry film lubricant. Coatings are heat cured. Pins are coated with PKSX* extreme pressure dry film"

"Coatings manufactured by TECH LINE*

CBC1*

- Ceramic thermal barrier coating

- Reduced piston temperature. Keeps heat in chamber longer, through the power stroke

- Increased torque and H.P. Increased combustion chamber efficiency.

- Reduced fuel consumption.

DFL1*

- high pressure lubricant with extremely low coefficient of friction

- reduces friction, galling and scuffing

- increases part life from up to 10 times

- ideal for piston skirts, cam lobes and any part subject to sliding or rotating friction

PKSX*

- designed for cylinder walls, lifter bores and valve guides

- extreme temperature and pressure lubricant

- reduces friction and wear

- bonds at 20 millionth of a inch

DFL1 is a thermally cured Dry Film Lubricant. DFL1 makes use of a unique binding system, to retain high temperature stability while reducing friction. The film thickness of DFL1, as applied, ranges from .0005" to .001".The lubricating ingredients in DFL-1 can lubricate at pressures above 350,000 psi. Part life increase and reduced friction the benefits. Life increases from two (2) to ten (10) times what is normal can be seen. The dry film lubricants may burnish until they are no longer visible, however, the active materials are bonded into the pores of the part and continue to provide protection. Parts will run cooler. Engine oil temperatures show a reduction. DFL1 is a primarily a high pressure lubricant and is recommend for use on any part subject to sliding or rotational friction. Camshaft assemblies, piston skirts and bearings all benefit from application of DFL1.

CBC1 is thermally cured metallic ceramic coating designed to be used on steel, cast iron or aluminum combustion chamber surfaces, piston domes and valve heads. CBC1 is formulated to be used in all engines, both 2 and 4 stroke. CBC1 provides a hard, durable thermal barrier overlay to any component. Provides reduced part temperature, resistance to detonation, increased combustion chamber efficiency. More efficient oxidation of fuel also occurs, leading to increased power output. CBC1 allows minimal transfer of heat through the coated surface thus reducing part operating temperature. In general coating the combustion chamber surfaces will allow you to run less initial timing with no loss of power (usually a gain will occur). You may also be able to run significantly less fuel. You should be able to run smaller jet sizes. Obviously no specific recommendations can be made as every engine combination will be different. Testing has shown significant power increases on a dyno. In addition certain changes can be made in such areas as tolerances, timing, jetting, that will increase torque and H.P. and are only possible through the use of coatings. Horsepower gains in excess of 15% have been measured in independent dyno testing"

I was wondering the same thing, at least if anything goes wrong I live a one hour drive to their place .
I have a 1980 Kawasaki KZ750 Ltd. I bought new. I recently managed to get it out of my garage after 28 years and put it on the road again (2010). I feel like a kid all over again. Since I have acquired 3 78 KZ1000 Ltd, 1 1981 KZ1000 Ltd, and another 1980 KZ750 Ltd. Love the LTD's.

It's an interesting idea, but two things concern me, although I didn't read all the verbage. One is, what brand are the pistons, the second is that coatings can come off in use. I'd want to see something to back up the product before using it over a known quantity like Wiseco.

My original cast pistons were Wiseco's. Good quality 1015- 10.25/1 pistons. They lasted two overhauls. One was ruined by dry starting. They don't make cast pistons anymore just billit ones. If those pistons are the same quality, they are a good deal. Only time will tell I guess. :unsure:

I'd be really worried about the coatings coming off and the particles being circulated around in the oil. While the coatings may have benefits in theory, I'd need some convincing over the security of a known product. If they are made by a reputable company complete with the coating then I'd consider the option, but if they are some Chinese made product, which is an off brand I'd steer well clear.

I looked at the 1015 pistons. They look like the stock pistons to me not 10.25. That's a red flag in my book.

I looked at Techline Coatings, they make the coatings and are based in USA., questions can be sent to This email address is being protected from spambots. You need JavaScript enabled to view it..

Coatings may be good and I'm not judging the parts in question, but one thing that bothers me about the text is the statement:

"Horsepower gains in excess of 15% have been measured in independent dyno testing"

That sounds like a snake-oil statement to me. If that much power could be gained simply by using coated pistons every bike and car manufacturer in the world would be using those coatings in order to remain competitive with or be superior to their competitors. Ed

I will send and email to Techline Coatings.
Yesterday night I saw a video on youtoube from this company. Yet the vendor only described the benefits of the coating in case of oil starvation...

May be a gimmick to improve a less than stellar product. Are the pistons made in Japan or via Japan?

Have to agree with Ed on this, if the coatings could give you a 15% increase in HP by reduced friction, they'd be in every car built for the increase in fuel economy alone and the people who do the coating would be retired and sunning themselves on a beach somewhere.

Some OEM auto companies coat the piston skirts with slippery sauce stuff. I'm not sure if it's the same stuff as being used on this motorcycle piston kit. At any rate, there is some precedent for using skirt coatings.
