Thanks heaps Blumbly, much appreciated.. now to find a model 8 base...

No there was no gasket between the two halves.I guess they were such a awesome fit they didn't need it.I usually put some gasket paste between them just to make sure,but it may not need it there,but I'd suggest to anyway you don't really want to have to pull it apart if it had a small air leak from it.
oh, true.. might grab some silicon gasket maker just in-case

Wow if the crankshaft is bent I suggest getting another one,as if it's not spot on it could cause all sorts of problems.Some things like extra vibration,damage to seals & bearings and other things like that.Could do quite a bit of damage to itself.
Will deffinitely be on the lookout for one.. though Im gonna give it a shot to see if i can correct it.. just in-case, are these crankshaft used in all the older 2stroke victas ? or is each different ?
On another note, the bearings look exposed (no rubber seals on them) .. when I replace them, do I need to get the same deep groove radial bearings? Does the oil in the 2 stroke lubricate them or will sealed bearings be ok ?
There's this kit on ebay, not for another 8days.. its a bit pricy, but not sure what ill be looking at in terms of cost..
