Jetting help for my 12 300
Thought I'd better start my own thread as I'm jacking another at the moment.
I was told by gas gas uk they run 40 pilot 175 main 7 slide N1ef top clip 1 turn out on as My bike is a standard 12 race 300 but I've added one of power valve spacers from elvis on this forum. I tried this setting and it wasn't too bad but not as good as my 09 which was smooth from bottom to top, my 12 a a mx type power . I'd robbed the 40 pilot out of the 09 so had to go back to the stock setting , I raced at the weekend and stuggled with that , bottom quarter was fine , then it seemed to be bogging down and not want to get into the power without a handfull of clutch to get it going , then I was faced with too much power. I've read good things about the nedj but can't get one as they are on back order in the uk , seems the ktm guys like them too So I've gone with glens suggestion of a cek/cck , they should be here tomorrow with a bit of luck. |

It sounds like you have one like ours. We've been all over the jetting map and can't make it/us happy. It's very frustrating, especially when others talk about having to tone theirs down.

Jan,
I should be in Crossfork mid-late afternoon on Sat. I have a pretty good needle selection I'll bring if you want to try some things. |

Grant, If you were using it in an older model bike particularly with the AS1 carb it might have been too lean on the needle diameter to give good response off the bottom. The different model carbs definitely require different jets. |
