what is stock on a 300? i have a sh1tload of mods and i was told to go 3-5 higher than stock and move the needle (up or down 1 i forget) so basically what is stock on a 300

I thought the stock main jet was a 128?

[300EXrider02]

no i just put mine in yesterday it is dj128

The main jet on a stock 300 should be 122. I am running a 128 in mine and it seems to be running real good. I just need to move the needle 1 notch, and it will be running perfect instead of good.
