[Hello everyone]

Welcome aboard mate.

I would replace the points if you haven't done so already, they have a habit of going on strike even though they look OK.

Hi Jamie,

Welcome to the forum.

That's a nice project you've got.

These guys should be able to help with parts/info :

If you would like to PM me your direct e mail address I can send you an owners manual and parts list which should help with the rebuild.

Thanks

Genuine Seeley, it even came with a nice authorisation letter from Colin Seeley.

I painted the tank cover and fitted genuine Seeley stickers and made a neat sidestand from a pair of Renthals, and generally tarted it up.

Made a neater silencer

It rode very well.

That's very sad news........

[Fuel/oil ratio for Alpina]

15 minutes ago, djr said:

It's an old air cooled , iron liner engine, not a modern water cooled plated cylinder engine,  so its up to you if you want to go as lean as 80/1,  100/1 ( which is fine in modern engines, but maybe a risk in older engines ?)

Short term it will probably run okay on just about any oil, at any ratio that has been mentioned,  but good oil mixed at a sensible ratio should give the best long term life for engine wear.

I once accidentally mixed up fork oil with my petrol ( picked up the wrong silkolene bottle)  and rode a trial with no problems before I realised , But I don't recommend it ! 

 

 

Did the forks work OK ?
