92mm pulley question ESS Re: Belt

Hi what belt length are people running
The original kit with the 96mm pulley came with a 6pk1509
ESS recommended the same length for the 92mm pulley , but when this was tried it was too loose.
A 6pk1503 was fitted which seemed tight
However it has completely slipped off!
When I had a look thereís a tiny amount of play in the tensioner pulley - is this normal and Iím wondering if this might be the cause? Or do I need a different belt length? Iím using gates.

I used a 1510 belt with the 92mm pulley. That was the one supplied by ESS when I ordered the pulley. Sounds like your tensioner pulley could be part of the issue. Good luck!
