Cool project, are you sure it's 64mm? That's like the S12 305 piston size. Bill Silver in the US just had several sets for sale.
What do you mean by S12? I've never heard of it.

Re: CA77 Starter relay

I've rebuilt a few CB77 relays but have no experience with CA77s but I suspect they are either similar or identical. Here are a few comments. First, is your battery in good condition and charged? This is a requirement for the starter to work. If you need to, a 12V car battery or portable jumper will...

Re: Bullet Connectors - Superhawk

I bought some connectors a couple of years ago. For very little (< $20 CDN) I got a nice plastic tray containing an assortment of 3.5mm & 4.0mm, male & female along with with some double and triple female connectors.

Unfortunately I'm not quite sure what the effect would be but I suspect it would either burn out the rectifier or let some smoke out of the wires.

Re: LOUD MOUSE

I hope he is well too. He has posted his phone number several times although I didn't find it with a quick search. Someone might like to try it.

That said, since this site came back up he hasn't been anywhere near as active and that may be all we're seeing.

Re: 305 oil seal leaks

It may well be the clutch pushrod. Pull it out and have a look. You will probably find that it has been worn down a bit at the seal.
