Ok I have a 1997 rm 125 and I have had terrible problems running it here in CO. So I looked at my settings on my carb and it shows stock: 50 for the pilot, 170 for the main. I have a 42 pilot and a 165 main in it from the previous owner. I finally got the clip right and the air flow pretty good and now I find that at idle I have just a little gas on the top of the plug not to bad, but when I open full throttle it is not wet, but it has a carbon deposits all around where it is suppoesed to be white. Now before it was soaking wet, not a dry carbon. If I cange my main jet down to 160 from the 165 should this maybe help?? Also when I am riding the bike does great except for when I open it up to full throttle and then it wants to bog out but it doesn't. I think this is related but any ideas would be great.
