JD Leak jet

Recommended Posts

I have just purchased a JD Jitting kit , plus leak jet kit . I am not sure what leak jet i should put in , or even if i need to. I have had some low end bog on my crf 250r 06 and i am trying to tune it in. I have put in a

180 main

45 pilot

Fuel Screw 1 out

Blue needle on 5th from top

300 ft

between 0 - 5 Deg C ( 32 - 41 F )

Any info would be appreciated , as i do not know very much about the carb.

Cheers.

First off congrats and welcome. Im impressed you got the carb out of that beast without any questions on removal. I had to ask a bunch of questions. Good going :thumbsup:

Im not going to be the best advisor, others will chime in, but a 180 main seesm abit high for your conditions. Im in Ohio, similar elevation, same winter temps. I guess the missing piece of info is "How does it run set like that?"

Its got a 55 leak at the moment,

Standard JD settings are 175 main , red needle on 5th from top on the 06

In conditions under 50 deg f put the blue needle 5th from top and go one bigger on main jet ( 180 is the next size they give ).
