Hi, i just bought a used 144 top end with 'more everywhere' from somebody and didnt get any jetting specs with it. I'm sure I'll probably have to go richer, but can Eric or anybody give me any insight on jet sizes that will work the best with the 05' YZ144?
I was told by steve125 that stock jetting was good since i'm currently having my '06 turned into a 144 I'm going to try stock jetting. He told me that my current settings (everything else is stock) only changes are a 37.5 pilot and the stock needle in the 2nd clip from the top. He adv me that I would be risking damnage going any leaner and that I must use a good race gas like something that is 110. but I'm having mine modified for more mid/top and to run on race gas.
