Anyone tried the Hyway titanium coated cylinders yet?

[HuskyFan1977]

Hyway has a new line of titankel cylinders. Has anyone tried them yet?
Here is a link to the big bore 066/660 titanium coated cylinder with a pop up. https://www.tijug.com/products.php?func=p_detail&p_id=7&pc_parent=5

I bought the Husky 372 52 mm popup. The plating is like a mirror. Still thin but Definetly harder. I was planning send it out for the spa treatment when my xpg gets done and do one (regular niksil) myself without the base gasket.

The Hyway rings resemble caber F cast (but rougher) so I ordered regular caber rings that should wear better FWIW.

For my use I'm sure they are fine. Production cutting or milling probably better off oem.

Hello, I have a 660 bigbore titanikel. Its looks Really good and timing Numbers is ok. Running it without base gasket. Squish is 0.023. Regards Bjorn

We have some inbound, but not in stock yet.

They hone them with a diamond hone because the stuff is so hard. Likely gonna mess up your tools a bit if you get to grinding.
They have to put a layer of nickel on the cylinder wall first in order to take the heat required for the titanium to adhere.

Would definitely be interested in how this works? My only experience with titanium is race valves and guns .
Titanium valves get changed frequently and the actual barrel sleeve of a titanium gun is traditional material, Both because heat cycling titanium makes it go boom! As in shatter.
I just haven't thought about it used as plating for internal parts? Any feed back is good .

I wonder what the proposed advantage of this new coating is.... Nikasil has been an excellent 2-stroke cylinder coating, and has a proven track record. I am interested in hearing about people's experience with it.

I should have them by the end of this week.

Do you have pop up pistons for a slant top 044 stihl?

Hello everyone dont try to port the titanikel cylinder. The plating is just to hard and brittle. The plating is chipping and lifting everywhere You touch it. Even after grinding With a Diamond Burr first. Hopeless to work With.

I can positively confirm what @Bjorn has said.
The hyway titanikel cylinder is not a viable candidate for porting. I started to port this cylinder and quickly found out how easily the plating lifts and chips.

Did you get pics before the work to see the factory ports?

Any duration or timing numbers?

82/124/102 without a gasket is what I timed it at.
The exhaust port roof and floor are extremely flat. The transfers have poor direction and allow for short circuiting out the exhaust. The tunnels are to tight to allow for good flow.
The intake port looks decent.

At least those aren't terrible stock numbers

The stock numbers ain’t bad at all. To bad the rest of the cylinder sucks.

 

[ManiacalMark]

I wonder if it's a hardness problem or an adhesion problem from the "different" blend of plating.

 

[Absolution]

I didn't realize there was another thread already on the topic I just posted over on the ricer section. I'm curious too.

I’d say both. The plating was chipping and lifting. In stock form they would likely be ok but I don’t think they’d perform very good due to the bad port shapes and direction

Check out how flat the roof and floor of the exhaust port are.

Damn. I see your point. The plating could be worked to help the flats but that seems impossible if your chipping it.
Try low speed tools like a drill and a fine stone
