I've noticed a jetting chart floating around here. Gave jetting specs based on elevation.

I got a trip to St. Anthony's comin up. I currently ride at 900 ft. St. Tony's is 4800 ft. Need to find out how far I will need to drop in jetting. Currently, running a 190 MJ, 45 PJ....

Any takers?

Yeah, I found that "calculator" and, it couldn't be more worthless. I am going up in elevation and, it is telling me too increase my jetting.

Less air, Less fuel.

Just curious, seems a little weird that u only have a 45 pilot with such a large mj... I'm running a 60 pilot an 178 main, 3rd clip, and I still pop a little on decel?... You would think that if u were needing to run such a large mj then u be running like. 65 pilot? But if it runs good it runs good I gues haha

I actually don't remember exactly what my jetting is. I know I have a 190 or 192 MJ and a 45 or 48 PJ.

I've got an idea of where I need to be for jetting in Idaho.

I only have a 50p with a 172m. you might want to check out your air fuel screw. I had a 48 with a lot of pop, put in a 50, and an R&D flex a/f screw and that fixed all my problems.
