I called emailed faxed and posted on HMF's forum about this... and they keep telling me the SAME THING you don't need to rejet... i will be in about 40degree weather with slipon stock fitler and lid on.. they claim no jetting required but will it be alright?? i mean.. i don't want ot blwo it up..

 

if ur worried bout it enought hten doa plug chekc. find a place where u can rev out a bunch of gears, pull in the clutch and hit the kill switch. take ur plug out and check it. if its got white on it then its lean, if its tan or a little darker then its fine, if its black then its rich(u wont have to worry bout that till summer). u can do that for every circuit of the carb and figure ur jetting for each one. 0-1/8 is air screw, 1/8-1/4 is pilot 1/4-3/4 is needle clip position and 3/4-full is main. might be a lil different to each carb but thats the basis i use for my 125

 

best thing to do is a plug check its not like its a pain in the butt to check the plug...
