Hi Max,
This bloke from Ballarat says that with a plug in the decomp his 24 nearly breaks 3 fingers when it kicks back, in the same way I found the PT's on a 24 bite. I fitted a F/C on a 24 recently that was obviously before they started fitting the decomp valves and there is no sign of kickback, but thinking about it it might only be a 125 but it certainly handles the tough stuff the same as the 160's When I get it back from my mate I will check it out.
