new 05yz144 jetting help needed

:busted: i knew what 2 run when it was a 125 but what should i run now? should i lean piolot jet bcuz of xtra vacum? its just a little time consuming with 3 kids u know! just anything WILL help! $10 for every response! just kidding!

I think i went leaner on mine when i had it, do a search.

I never got it running right, I had the Athena kit, it kept melting cylinder head o-rings no matter what i did. . .

Did you ever figure it out.  I have a 05yz144 and need help also.
