Searching Anton Alers

Hi - can anyone get me in contact with Anton Alers by email? Met him in the 70's at the Austria 500GP where he found Roger DeCoster his hero to be a very normal and open guy. From Sittendorf we gave him a lift in our car to Holland. Thank you Harry van Hemmen, Dutchman (67) now living in Spain

Hodaka dirt squirt best time of my life

I grew up in cairns Queensland and a friend Steven Milne had a hodaka while I had a Honda 50
, I was making dirt tracks over the road from my house and behind the house.
I upgraded to a hodaka 100 dirt squirt and had the best time of my life riding any free time possible, it was up to 1975 so a while ago but the memorys are still there so it is great to see any hodakas now.

Anyone have any success salvaging an old rusted Bultaco motor.  The project is a very early Model 3 or newer 4 speed engine, with the external oil seal on the drive chain out put sprocket.  I am not interested in saving the studs and logs nor most of the internals, but all fasteners are extremely rusted and Penetrating oil, heat and ATF have not been sufficiently helpful..  I just need to save the castings and some major components of the internals.  But this 'sucker" is locked up and every…

Carb woes ...

Today my VM32 carb was certified as deceased ... and so I need to buy a new one. It is for a Suzuki TM250 (1973). Is it worthwhile going to the VM34 ... if so, what would be the jetting / setting suggestions? It has the standard pipe (no silencer add on) ... and a unifilter foam air filter.

Any help / suggestions greatly received and appreciated.
