10/16/2023 8:24pm The recent cooler weather really affects the v2 stroke 38mm Keihin ? We dropped from 95 to 65 degrees in 3wks and it's causing decel pop surge-like symptoms. Current jetting: SJ #48 MJ #178 NC 1.5

10/13/2023 9:23pm I'm wondering now if loat height is why I have to have a 50SJ & 180MJ? I don't have the correct tool to accurately measure it. Very hard to eyeball it.

A two stroke that doesn’t idle has better throttle response then a carb set to idle.

Why do you want an mx bike to idle for more than say 10-15 seconds? No factory racer back in the day idled for more than that.

10/10/2023 2:52pm I think I finally have my '00 CR250R jetted right. I've gone up & down the pilot jet scale from a #42 up to a #55 back down to a #50 w/ the NC in 4th & the AS out 1.5 turns. Does < that sound about right? Once hot it won't idle which I read is normal or optimum...
