hard start today

[geezer]

ok i have just got done adding an emgo muffler and a filtro air filter to my 99. i shimed the needle a tad more than what the washer we all just flip over would let me and moved up to a 136 mainjet. my idle mixuture screw is at 2 3/4 turns. ever sence owning the bike i have had instant starting everytime, cold or hot, choke or no choke. well after work it was in the high 90's and it took quite awhile to start. i say to myself, ok better report this to the forum and go on my way. down the road at a light i forget im in gear and let go of the clutch and bam i kill her. go to start it and its very sluggish, you could feel and hear it barly chug that cylnder. so i belive im jetted to rich for this warm weather. i might just turn down the mixture screw and go back down on my needle and main. what do you all think? before i forget i needto check my spark plug and see if its black
