Nice job!

One hand fashioned copper head gasket. Not perfect, but should do the job.

Lloydy1,

I used an adjustable c spanner to loosen the left hand thread cam sprocket nut. I blocked the cam sprocket with a piece of hardwood. Some sharp hits with a hammer on the C spanner did the trick.

The adjustable C spanner is similar to this one - you would need to check the size.

Hi,
The part that looks home made may have something to do with selecting the 5th gear or to stop false neutrals when changing gear.
I know you could buy a part that fitted on the shift arm and I have one but it looks nothing like what you have.
It's a nice bike and looks like a lot of work has gone into it.
You are welcome to pop round to my place and see my bikes anytime as you are only in North Wales.

Hi Alan

What you say makes sense to me. I cant think of anything else it could be.

I have sent you a PM in reply to yours.

Thanks Dave.

Hi G

I'll give it the heat treatment before fitting it.
