83 250r Jetting opinion

[zoomerman]

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

good luck to u on the jetting of an airfooler. I have 2 of them. one that i ride is now bored 80 over stock, dg pipe/silencer, open air box, 120 main jet, 38 pilot and its still rich. read the jetting forum. its great info. also, i have a rear shock. its in decent shape. pm me..........

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.

So put the 130 main jet in the 86 carb and do a plug chop? i was thinkin i should go with a richer jet but i don't really know.
