Stock or suggested jets?
I'm planning to redo most of my 1999 CR125 Honda and one thing i am planning to do is replace the Reed and with this i am going to probably rejet the carb. the honda manual says that the stock sizes are Main Jet: 177 Pilot: 55 but on fmfracing.com they have suggest jet specs and they suggest Main: 170 and Pilot: 52. i do not have a FMF exhaust, i have stock exhaust though.
should i replace with fmf suggested jetting settings or the manual jet sizes
