Newbie carb setting question 1992 RM250

[ukrm]

Hi from the (not so) Sunny UK !

I realise this is a tricky issue but I would love to hear some jetting suggestions for my very rich 92 RM250 :whoa:

Its very boggy low down & currently running a 370 main jet, std needle & pilot.

Cheers

Steve

its hard to say what will work for you its all on how your bike wants to run elevation, temperature, humidity are all big factors in jetting you should do a search in this forum on how to jet, and read plugs. jetting is a skill but can be done with the right info on how to jet, but youll have better results by reading the plug on your bike Here is a link on how to read your plugs. but you need to consentrate on one circuit at a time, start with your main jet, wide open in about 4 gear and pull in the clutch and kill switch at same time, read plug. then go to the needle same thing but 3rd gear and half throttle pull in clutch and kill, read plug, same for the pilot, or slow but 1/4 throttle, and second gear, read plug then, 1/8 throttle for air screw.
