Hi Rick

I'm Still waiting for my parts book to arrive from Spain so I can't confirm part number etc.

BUT I bought a set of rocker off ebay from a guy in Thailand.

They have M8 threads.

I was told by an all knowing source in Australia they had the same rockers. 125 & 160

Seeing as my engine & frame are VERY early 58 they still may have been using parts from 100 but not too sure as an early 100 parts book is harder to find than the 125 book has been.

Can you give me an idea of where to get the M8 screws ?
Please dont say any of the usual places ( guzzino & bevelheaven ) as I find $85 aus + delivery to Australia a bit rich for my poor old pocket.

Like Jordan said elephant foot adjusters are readily available. You can get a set of 8, watch for any wear and swap in a new pair easily if necessary. There are a lot available and I have no idea which are best but there is plenty of info on the web about them.

As for part numbers have you tried contacting someone that might have the early parts books? Malcome Tunstall of Syd's Cycles may have them, also Jonathan White of Prova in Cincinnati probably has them or he would just know what you need to know from experience.

Try a Porsche or VW air-cooled performance parts shop.

Thanks Guys
I have not seen the elephant type only the original ball type & a solid mushroom head.

I didnt know that they used that sort of valve adjustment in porche
