Thanks for the replies people, I think I have a plan now though after many hours of browsing this forum and some go kart ones.

1: I've shaved roughly 2.5-3mm of the head using a belt sander and then a glass table with some sandpaper on it. I'm planning on putting a bolt in the decompressor hole and filling the void with liquid metal.

2: giving the bore a quick hone as I had my neighbour over to have a look after i realised he's a 2 stroke model boat and plane expert, and he thinks it's pretty good.

3: replacing piston rings if I can get them alone but if not I might just buy one of $35 rebuild kits from ebay

4: porting the intake and exhaust, wider but not longer so my timing doesn't change.

5: 22-26mm carby from ebay

6: a 2 stroke exhaust from a pit bike or something similar. As long as it's the same width I figure it should be okay

6: other than that just a very nice clean and paint. I'm thinking painted block with a polished head

I,ll get some photos up tonight
