What can be wrong with a 2-stroke cylinder head that it needs changing? Is it cracked?

I didn't know Yamaha did a Y-3 head, i thought they were all marked as Y-2 and distinguished by the model number. i.e. 3mb00 etc.
Whats the model number of the one you are looking for?

[joycee125]

hi mr krispy i now they did the Y-1, Y-2 and the Y-3 they all look the same on the internet but i dont no if they are or not but Y-3 is the only marking i have on my cylinder head other than yamaha. hi pete it has a massive chumk out of the culinder head were it meets the bore so there is no compression cause it is all going in to the water system and all the water is going down in to the exhaust thanx joycee125

[Mr Krispy]

The only difference i'm aware of is the squish band on the 3BN type has a more pronounced ring that reduces compression as a form of restriction.
3BN (Y-2) (notice the raised squish band)

3MB(Y-2) (how it should be)

Y-1 is the cylinder (barrel) and Y-2 is the head!

Is the damage that bad it can't be skimmed?

What year is your DT?

[joycee125]

sorry mate i dnt no what year it is cause i brought it as a field bike with no vin plates or nothing it only cost me £100 and my other halfs dad is going to try and skim it but it is deep in to the cylinder head and it is exactly the same as the 2nd and 3rd picture u put on joycee125

[Mr Krispy]

Well if you need a replacement get a 3MB head.
For £100 it sounds dodgy to me, good luck explaining to the police the lack of engine numbers when you get pulled.

they gotta prove it first and no vin plates good lick to them and it not on the road its a field bike and i bought it that way

[Mr Krispy]

I sense some recycling on the horizon
