Why is this?  Is there a good thread that gives the reasoning behind this?

KXcam22:
The main reason to start in 3rd is to make up the time while everyone else has to shift into 3rd. Typically you can gain 5-10ft by not having to shift, but you need to have the power to pull it and it is less forgiving on errors in technique.  Done properly, no one can stand against you.  2nd is much easier to do, more forgiving and is more commonly used.  I typically start in 2nd on my K5 even though I can pull good 3rd gear starts.  Last time I started in 3rd at an MX race was because the tranny was stuck in 3rd (in practise).  The K5 did get 2 holeshots and 2 moto wins.  Not many bikes can compete in one gear but the K5 can. Cam.

At 155 lbs., the only place I would end up starting in 3rd gear would be on my a$$ !!!!   LOL

2nd gear starts 1/3 throttle, and as soon as the 5 honkey is putting down usable traction... WO !!

Wanna impress me? Do a 3rd gear start down a wet, muddy straight away on a KX500 !    LOL

I know exactly what you are saying. I weigh right around 150lbs with my gear on. Even sitting as far forward on the tank as possible, I can't do a 3rd gear start unless I murder the clutch. If the ground has good bite, I have a hard time with 2nd gear.

Last weekend I went to the sand dunes, the drag strip there is right down by the water so it's always has great grip. With the paddle tire and me droping down to a 12t front sprocket (since last time I actually tried launching hard), I couldn't keep the front end down. If I wasn't fast with the clutch lever when the tire hooked, the bike was going over.

Actually 3rd gear starts help tame down the hit. BTW.....you dont just dump the clutch....you feed it out controling the amount of power put to the ground.
