Change in Silencer I.D.
Posted: 07:56 pm Feb 03 2017
A month or so ago, I put a new FMF TurbineCore 2 silencer with spark arrestor on my 05 KDX220r, keep the same chamber. Last night I noticed that in the process, I had gone from a 1" diameter at the outlet, to a 1 1/8" diameter. Now I'm wondering if the mixture would be changed significantly and if I need to make any change to the jetting? Any input is greatly appreciated. Thanks, Phil
