I just changed my old FMF Fatty with a ESR TRX6 pipe and now it has no low to mid. The quad acts like it doesn't want to pull when under a heavy load unless it is on the pipe! It runs great on the top as long as you keep it on the pipe. Currently it has a 38mm PWK carb on a stock cylinder. ( No port work or big bore) Stock air box with lid and snorkel.

Pilot jet: 52
Main: 170
I am a 1500 ft above sea level. I have no major motor mods other than pipe, carb and reed spacer. What jetting should I use?

Thanks for the help, MIKE

The plug is a medium tan color. It screams at WOT, it just bogs at 1/4 to 3/4.

The TRX6 pipe is a woods/MX pipe.

lean out the needle, that should do it

btw, be carefull pullin the slide out of the carb, u can break the needle off right at the clip

I agree w/Bean,,go to next leanest position

but before sure to check a new one after a fairly long run...
