I have a full detailed, lap history of my NXA. I have printed out all the practice laps and race laps for every race John rode the bike and the Oliver's Mount meetings i have even have it verfied by the circuit and been given an electronic scan of a signed pic that resides at the circuit office.
Anyway the bike has done 1069 miles from new and of these miles John did 579. No doubt he wasnt riding it like he was off down the local sunday cafe for a bacon sarnie and a cup of tea!
The other 490 miles is me pussy footing about like the doddery old git i am becoming ... (at a rate of notts i would rather ignore
).
The cylinder bores look amazingly good and under my ownership all top end parts have been replaced before 300 miles with OEM HRC and i have no doubt Clive P has not skimpt on the comsumables as he prides himself in the reliability of his bikes.
So the question is .... As Ever....
How far do i push the Cylinders and the Crank at this stage?
I know somebody with a CMM so i could get the cylinders accurately measured but what exactly am i looking to measure?
I see loads of bikes with 'spare cranks' that are pulled before full mileage BUT in reality who in their right mind is going to put a crank back into one of these things that hasnt quite reached its HRC Manual mileage? Why not just do the whole mileage and then some ... then lob it in the bin?
Does that make any sense to anyone?
