Low down / tickover issue HELP

[stevehipkiss]

Hi all,

Bike: 2007 ec 300

Just changed my silencer to a Gasgas 'Racing' silencer, runs superbly after tickover,kicks powervalve in slightly quicker.

Problem Ive got is that on tickover it feels and sounds like it is hunting, a kind of up and down on the revs, as I said once moving its fine...Anyone help ??

Please dont guess..you either know about these things or like me,you just guess, my guess being it needs a different jet....

My jetting is currently 178 / 40,
