    Arrow 83 250r Jetting opinion

    I recently put a 86 carb, Boyseen power reeds, and dg national pipe and type two silencer on my bike( 83 250r) but haven't started it because of jetting issues. Around what size main jet should i start with? the stock main for the 86 carb was 142 and pilot 50?i was told well it has a 52 pilot jet in it and a 125 for a main jet. The 83 carb comes with a 50 pilot and a 130 main. I would like to start jetting rich like stated, but i don't really have any idea. Should i buy a jet kit and start with a 138 or should i start bigger/smaller? any input would be helpful.

    Thanks,

    Evan

    Throw the liquid R carb on and do some plug chops. The jets should be large enough to keep you safe for the first plug check.
