Strange question

[ka-ja]

My original enquiries (1985) and subsequent conversion of my 400/4 to Yoshimura racing trim, the oil cooler was only considered necessary when fitting Carrillo? conrods with bigger diameter gudgeon pins, allowing engine max revs up to 16,000rpm,standard  conrods were considered OK to 12,000rpm by the tuners.

That strange

My tuner said taking the engine to 460 increases the normal oil temp so the requirement to add the oil cooler?

I am only giving the tuning advice I received from the people that actually raced them in clubman's 500cc racing back in the day.
