Primary chain

[Luckydug23]

Hi
Anyone got a lead on a primary chain for an MX4. Mine, original, seems to have quite a bit of slack. What sort of deflection should it have? around 10mm as checked at centre of top run?
Regards Paul

That's way too much. I always insisted on renolds primary chain when I was racing but even then it was difficult to get hold of, I used to buy a roll from my local bearing supplier
