Hyway 45mm Cylinder

[BonScott46]

Picked up this Hyway 45mm cylinder with a meteor piston for a swap on a Jonsered 2152. I have little experience with cylinders and saws in general to be honest, am wondering about a couple things. There is a band of checkered material at the top of the bore from the squish band to about half way up the the decomp hole. I can feel it with my finger, is this normal? Here are some pictures of the bore. There is also a spot under the transfers clutch side with some discoloration and a pin hole but nothing I can feel with a fingernail. On a side note I also noticed that the transfer tunnel dividing wall is not continuous and has a big gap. I am assuming that is the same on the OEM. Anybody know what the idea behind that is? Does it have to do with keeping the pressure equal in both sides of the tunnel? Thanks for any information.

Appears to be chatter marks from the boring bar prior to plating, need to sharpen their bit.

Is it good to use as is?

You can use it, it probly won't last forever. That hole in the plating under the transfers worries me.

I usually find the Hyway jugs are made and machined very well but if you are able I would return that one to the supplier .

I have contacted the supplier to see what they say. I am confident they will stand behind it. I wanted to see what you guys thought of it, I did not think it was acceptable but wanted a second opinion. Thanks.

Wow!
They really take their chamfering serious huh?!

Yep, that would be going right back in the box.

Supplier is going to send me another one and check it first. This is the same guy Tor buys stuff from, great prices. Kit came with a meteor piston and a caber for 750kr to my door which is about 80-85 bucks at the moment.
