Purile rantings, now come on Victor.
I open a simple post requesting information and you turn it into a childish slanging match. You failed to offer anthing constructive and seem intent on nit picking, taking everything literally.
Underlying resentment, i think not! i have a lot friends in the 600 class and have raced one at Mallory, i have a lot of respect for all racers, you have too. But not those with 5K engine tunes and 732 motors.
So, take the blinkers off mate, engage (or find) a sense of humour and do your thing, whatever it is.
You don't have to share your 600 championship/IOM winning secret, i mean you must have WON every class throughout your esteemed career to be so knowledgable and quick to dismiss others opinions.

(something tells me this is going to be a tit for tat, lasting forever and getting boring very very quickly thing)
