Never did try them and I cant remember piston off hand. The piston was for a different make saw, then what it was listed for.

Mako is a aftermarket brand of parts distributed by Tilton Equipment. Fairly extensive selection for both Husky and Stihl. Whatever Jonsered models are common to the Huskys are of course covered, but there are no parts for Jonsered specific models.
Some of the parts are of "Asian" origin. I doubt these parts are unique to the Mako brand. They are likely sourcing them from suppliers that are making this stuff under different labels we've already seen. Some of the parts are Tecomec, which are all super quality. (and cost more) The difference is in the part number prefex, either "TL" or "TM".
Experience so far on the asian has been limited, so I can't say it's all good yet. The 372 big bore kit looks really nice. Beefy piston, very clean casting. Has that dark finish on it like the bailey's kits. Regular 372 is the standard silver finish, and doesn't have the same quality look. I did put one in a 365 a couple weeks ago. Saw is in commercial use and has been doing fine. I put a Mako piston in a 575 of mine. Only ran a tank and a half through it to date. Seems OK. A buddy used one of the 395 kits, and it's been OK. On the down side, a customer said he bought a 288 kit from another dealer, and the surface where the intake block meets the cylinder was screwed up.
My big bore kit is going on a Jonsered chassis. I'll create my own Jonsered 2176. Even going to make a "2176" decal by using decals from a 2171 and 2186. 8)

-
The suff is junk. Hyway IMHO is much better!

I have only read that by the same seller of mako stuff. Kind find it anywhere else to confirm.

I had owned a evo harley in 93 and I just dont remember anything about cylinder coatings. So doing a search. http://www.powerglides.co.uk/ar/bor_hon_tech.php

Sorry for getting off track. But this HD stuff was interesting. I want to know all about this coating the seller says mako does for HD in its cylinders. Notice the article says nothing about coating during boring and honing.

I just read the seller info on mako. I question the chrome being used over nicosil. Must be a reason why everyone else even OEM went nicosil.
1. Time in the industry: 30 years plus.
2. Material: MAKO is top of the line Quality cylinders with material coming out of japan the metal is AC4B.
3. Process: Before coating the cylinders are put through over 13 different process.
4. Thickness: The coating is 0.04 to 0.06mm of Chrome which does increase he life the cylinder.
5. Machining: Machining is done a CMC tool centres machine.
6. Die Casting Process: all of the cylinders are made by slow Gravity fed die casting, This process increases the weight of the cylinder which enhances the performance over and has been proven.
7. Tooling: Each cylinder has limited life and are replaced as the manufacture pf 50,00 pieces, further this process tools are checked more frequently and maintained on a monthly basis where others do not.
8. Quality Control: Special instructions are done on each cylinder inlet and exhaust ports which includes chamfering of all burrs, every 20th cylinder off the production line is thoroughly inspected to ensure quality is still number 1.
9. Nicosil: Nicosil is a good coating and has long life, but Mako stand behinds the Chrome coating process and thinks and feels paying the extra for Nicosil coating is unnecessary since Mako believes the Chrome is as good if not better.
10. packaging: All Mako packages are well wrapped and placed in a high quality box with full description of the product.
11. Supplier of: MAKO is also a OEM supplier for Chainsaws and Motorcycles.
12. Quality: Mako believes and has done research that their product has a 3 times longer life than any other Cheaper Aftermarket kit. 90 day Warranty

These are some pics of the mako piston and cylinder kit. Sorry my pics are not the best. Can't seem to hold still or not shake a bit. Over all I am pleased with how it looks. The intake and exhaust are smooth with no casting seams. The combustion chamber looks good as well a smooth transition from squish band to cc. Let me know what you think and if you want anymore pics
-
Chrome plated? Pics look good.
-
It's rather unusual to see a current production Chrome plated cylinder bore. Most are Nickasil.
Don't use Nikasil rings in a chrome plated bore.
-
I talked to another aftermarket supplier and ask about mako supposedly coating the HD cylinders. More or less just a smile and rolled eyes reply IMO. ::) :D ;D
Using Chrome and their reasoning is BS IMO too. Even the other aftermarket folks went from chrome to Nikasil.
-
Not sure how to tell the difference between chrome and nikasil. The supplier says it is chrome. I think it looks good. But only time will tell. It looks as nice or nicer than the NWP kit I have seen in the past.
-
Chrome is electro plated
Nickasil is a molten metal that is sprayed onto the cylinder wall in sort of a torch application.
-
Pretty sure all the modern cylinder coating are electroplated and honed to final dimensions .
-
Plasma sprayed bores are more common on auto motors. I think k Ford is using this process in the newest mustangs...
-
If you work with the different kinds, it is easy to tell them apart.
-
NWP started with chrome on their BB and went to nikasil. IMO must be a reason for it. mako saying they are sticking with chrome to me is just cost savings to them which = better profits. All JMO and thoughts.

Depends on environmental considerations as spent chromic acid disposal was a real consideration in some countries.
