For a mate, he will also consider both cases or complete motor.
Hell, he may even buy another complete bike, i think he's trying to corner the market in obscure unsought after models

[Rossvickicampbell]

strange characteristics he has - would be a good mate of yours eh Geoff!

happy New Year mate 

[GMC]

Happy New Year to you too Roscco.

Yeah, it’s the sort of mateship that money can’t buy,
Money doesn’t seem to make him go away either.

Hopefully if I can find a case for him then I won’t have to do some obscure welding job on it.
It seems the main bearing fits into a ring that is moulded into the case and this ring has come loose with up and down movement.
Didn’t know there was such a ring in the cases!!

i have a 576 and a 1R8 set of used bottom ends in the shed, not sure what they are but there that small cc size, any use ?

[GMC]

Thanks Freaky but I'm not sure what 576 & 1R8 are from either.
I assume they are the first digits of the engine No which would specify the model.
Anyone know if these numbers would be for the models in the want-list I posted above?

[Nathan S]

576 = DT175C = twinshock bike = cases no good for IT (whole motor would work, but...).

1R8 = something the Yanks didn't get. Most likely a DT125 or 175 monoshock, at a guess.

Nathan will put me straight , but i used a set of crankcsaes from a DT175 mono for a YZ 125E motor with rooted cases , was a straight forward swap.

In theory they should work for your mates IT Geoff  they are easily sourced and not generally flogged like YZ or IT cases

Geoff, let me know if he turns up any spare yz125f tanks, mine's looking more than a bit secondhand at the moment

[Davey Crocket]

Will a G fit Paul?

[mainline]

no, different shape, fuel tap on other side, different mounting points too I think. They look the same at a glance though.

Lets do that
Do you know what model DT I should look for?
Nathan tried to tell me something similar but my eyes just glazed over.

Daves actually looking for a better 125 F tank as well
And he's still looking for an airbox, well actually he's sitting on his arse while I search for him

should have some 1w1 parts will check next week
