I removed the Headlight frame today. It's a bit out of shape...

So I have straightened it up and welded up a couple of cracks in the tubes. I will have to check it is OK once I put the headlight into it...

I have got the old headlight shell in it at the moment which I have been repairing, but I have given up on that and ordered a new headlight, which will hopefully be here this week along with a few other parts. Looking forward to putting them on the bike.
