Hey fellas... i just did a new top end rebuild... before i did this rebuild the bike had ported cylinders and a Cool Head w 17ccdomes... I no longer have the ported cylinder or the cool head! The main jet was 340.. I went back to a stock cylinder @ 64.25mm bore and a stock head!! I changed the main jet to 270!! but i did not change the needle or pilot jet..( I dont even know where the pilot jet is) So that would help!!! Im at a little over 100ft above elevation.. I have t-5's v 3's, and i have a pro design air filter kit and i run with the lid off. My shee fires right up. and idles fine, but smoke is pouring outta the exhaust.. and I place my hand over the tips and i get a black oily residue onmy hand . Im assuming im running too rich.. Please imnot an idiot its just my first banshee rebuild.. Im not trying to ruin anything. im being very cautious here!! So i would like to know if the oil residue is from me running to rich.. remember i didnt change my carb needles or the pilot jet.. I was hoping someone can give me an idea of what i need to run.. I would do the sticky of what jets to run.. but i dont know what pilot jets or needle ii am running.. I must to retarded bc i dont know where the pilot jet is!! if anyone can please help out a newbie its appreciated.. I dont need a buncha people telling me im an idiot and etc.. I just dont know the nature of the beast yet!! any help would be greatly appreciated!!! I also tried the shout box to avoid a post. but noone responded!! So this is my last resort!!! THANX AGAIN
