Finally got some track time with the big fellow but the gearing felt a little short. Currently has 14/46 what are y’all running?

Not sure what you mean by short. Short as shifting too much or short as in no top end speed? FWIW, I am planning on swaping a IT465 bottom end to my YZ (G model). The enginer can pull it and the wider gear ratios makes the power more managable. YZ were used alot as desert sleds so "gearing up" was commonplace.

Pretty sure 14/46 is the standard gearing. I guess it depends on the type of track you ride. If it is tight and twisty maybe put a 48 on the back.

I had standard gearing on mine and it worked quite well on any type of track. Short shift and let the torque do it's work.

When a bike is geared "short", it has a shorter power spread to reach redline ( large rear sprocket). If it is geared tall, it has a much larger spread to redline (small rear sprocket).

Ok, now we are on the same page. I don't know what skill level you have nor do I know what type of terrain you are riding in but a strong point of the YZ465s was thier ability to rarely need to be shifted when racing. It was not un-typical for a rider to leave the gate in third gear (aka the "Working Gear") and rarely have to shift out of that gear for the entire race. The engine was that strong and flexible.
