Mototrans 250 (69mm bore) Cylinder Head needed; can you help??

Postby BamBam » Thu Apr 15, 2021 2:44 pm

Hello
I have a Spanish 250 engine and the Cylinder Head has gone missing, presumed thrown away by accident during a workshop move!!

Does anyone have a suitable head to sell please?

The head is of course different to an Italian A series head; most easily obvious by the oil way spigot positioning and the recess for the cylinder liner top size of 89.95mm

Hello Eldert,

I would prefer a complete head with decent rockers and cam lobes (I have the Bevel Shaft and Tunnel); however I can source rockers and I have a cam that can be reprofiled if only a bare head is available.

Thanks very much for your help...

Hi Eldert,

I thought I had found a 24 Horras camshaft for the cylinder hed you supplied me but it was actually n Italian 250 camshaft and not suitable. Do you know of anyone who would have a 24 Horras camshaft or have the dimensions and profile so I can have one made up??

Thanks

Paul
