Mmmm, likely didnt want to speed....90limit? Many many moons ago I worked for a Truck manufacturer, and Linda Lusardi was our racing 'mascot'. Initially the tractor units were unlimited, but due to the pounding the tracks get with 7tonnes hammering them we were limited back down to just 100mph....so slow, (water filled and underslung steel spare wheel, was just one of the tweeks)
Quite! Without a cage round the oil pick-up I bet he is starving the engine oil system......Sure fire way to run bearings... (Are those some form of wheelie bars we see underneath?)
I think that’s the linkage hanging down under the rear end???!! That said still not right in the head
