Thanks for the comments,
The budget is if I have the money it can get more shiny bits added, I was looking at about £1000 for and engine check and maybe a few dress up bits. As i am in no rush I will just look out for any bargains. If i set a strict and proper budget i will only be disappointed everytime I go over it and then the new one I set again. Great point on the new cases as I will prob be easier to move the internals over during the overhaul and replace the bits that are on the way out.
I was looking at a company called Coba Valley Cycles based in Dorset, I sold a HUC frame last year and the buyer recommended them, does anyone have experience with them ? For the fab work (tank / subframe). Also anyone have experience with PHW (pointy hat wizard) based in Essex, again for fab work ?
If anyone thinks this is "similar" to another frame out there let me know please, I know there are loads of oneoffs out there but worth a try.
I will keep you posted with any progress but may be a few months as I have like most too many projects with are forming a queue, and the YZ80 is next on the agenda.
