my 2001 125sx was running great last weekend. this weekend i couldnt get a bog out of it no matter what i did or anyone else at the track. just off the bottom it bogs. i`ve changed every jet up and down and it wouldnt matter. the bog was still there. couldnt come out of the corners unless i kept it revved out. could i have a electrical problem happenening? i changed the reeds the main and slow jet, dropped the needle and raised the needle and still it persists. it drove me nuts! does any one know something i dont? has this happened to anyone else?
