I suppose if you want to split hairs down to the transitional surface of the tapering cones of a 108 jet drilled to 117 vs. a standard 117 jet there probably is some infinitesimal difference on that surface. However, there was already a taper on the 108 jet and the orifice was only opened up .004", about the size of a hair.
Anyhow, I'm not looking to debate something which I really have no expertise in. I'm just searching for practical answers to get an inexpensive Chinese motorcycle to run smooth without hiccups.
All positive input is appreciated.
