I bought my 00 yz 125 from a trusted friend who barely used the bike. He advised me to run 40:1 so i always use Yamalube 2-R however when i got it i would constantly foul out plugs and then i decided to tune it. I cleaned the airfilter out and made sure the exhaust was mostly clear and then went on with the adjusting.
I ride and live at an elevation of 90-100 feet so its basically sea level.
I had to go from the 3rd clip (stock) to the 2nd clip on the jet needle and 1 1/2 turns out (stock) on the mix screw and i have the idle set so it barely idles at a stop and dies after a few seconds.. I have the stock 350 main jet, stock 35 piolot jet, and an 80 starter jet.
I must say that the bike felt like a completly new bike after the tuning i made. It was absoutly amazing.. but then about an hour and a half of riding the plug fouled out.. so i cranked the mix screw out another 1/2 turn so its at 2 turns out now and threw a new plug in.. seems all good now because it ran great for the rest of the day. I am going to pull it out and check it tomorrow. If its nice and tan then i am going to be soooooo happy. But if not then its back to the drawing board for me.
Now i barely get any oil out the rear of the bike (but there still is a tad).. but to be honest an article i read which i found recently posted in another thread here, has really got me interested in going to full synthetic at 32:1 and setting my bike all back to stock specifications. What are your opinions guys?
Also.. what elevation are the stock recommended settings set for?
Thanks!
