Hello. I got a 2003 RM125 with a pro circuit engine and i had one question. I Got the bike from sea level, no spooge what so ever. Than i took it to my house which is 6500 and it would kick over but it wouldnt idle. I had a friend show me how to ajust the idle screw and now its fine.but the thing spooges horribly alll over. I mix at 40 to 1

Any tips would be apperciated

Exactly the opposite, you'll run lean and need to richen it. Just take note of what air screw and jet settings worked at sea level and then switch back and forth every time you change altitudes. It doesn't take but a few minutes. If you are going to be going back and forth a lot, I recommend changing the main jet vs. raising the clip position because it takes less time to swap the actual jet than it does to move the clip.
