Anyone here running a BR2J head at 4000 rpm?
I've wound my inverter up to 133Hz which gives 4000 rpm but didn't want to risk damage.
Seems the spec sheets show 2300 or 4200 rpm - is there a difference in models here?

Had a quick trawl this morning - it seems the differences were possibly between the J head and the 2J head, the J had a smaller motor.
My head is definitely a BR2J and it also has a plate on it stating not to engage low gear at speeds above 3000rpm so i can only guess it went to 4200 once upon a time.
I'll keep an eye on the temperatures and see how she goes.
