Hi everyone. I just became a member of this site and a good one it is. But neway heres the story i just got my motor rebuilt on my bike. 2000 rm 250 to be exact. I went riding today for the first time on it and i fowled out one plug. it was oil fowled. so i put a new one in it ran good for a while. brought it back home and it wouldnt start. so i got it to finally start. took the plug out cleaned it a lil starting fluid fired right up. the second plug was starting to get alot of oil build up on it. Whats the deal? i have boysen rad valves i just put in it, the needle in the carb it set at the third position and the main jet has been changed down from 158 (stock) to 155. and my gas oil mix is 32:1. should i decrease the fuel oil mix to ,like say 40:1 or 50:1? any help would be greatly appreciated. thanks
