    Africa Twin

    Dominator / FMX
    I'm hoping to build a special dominator motor with a high compression piston - say 10.5:1 No problem I thought, as Wiseco do them for the XR650L - which is the same as the Dominator right? Does anyone know 100% for sure if this is true of all XR650L motors because the Wiseco catalogue does not...

    Dominator / FMX

  8. One for the collection...

    Africa Twin
    At Moretonhampstead Motor Museum last week. The old Isetta brought back memories, too - I had one as a sixteen year old. If you're down Dartmoor-way, the museum's well worth a visit, particularly if, like me, you grew up in the 60s: many/most of the bikes and cars displayed are everyday...
