Big Bore Kit HELP!!

ok so i bought this

ww313

and i need some help with it. does it not need a top drum peice (where your plug plugs into) its a different sized plug and it makes me mad because i dont have this top peice for the head so i cant even use it? please somebody tell me what to do nothing ever goes right i just want to get my bike working and i go out and spend some money and everything i buy is not what i thought. I bought the Dell Rep Carb and have no idea how to use the throttel cabel with it. it makes no sence at all and if you know anything abou that please help me too. Bought new fuel filters but the stock line on my bike is hella big! why is it so big???

okay i believe thats the same BBK i purchased, there is a spot where the spark plug screws in its like on the top where it normally goes, its pretty self explanitory, theres a bullitin on here about how to install it i think i asked the question about installing it lol, be carefull with the piston rings, i broke my first set... okay i had the same problem with my fuel lines as well, my fuel line was 1/4 ID ( inner diameter) and the new dell rep carb is 1/8" ID so you have to go and purchase a brass fitting i bought 2 a 1/4 and an 3/16 they screwed into each other, and i purchased some 3/16 fuel line at Pep boys total it was about 8 bucks the 3/16 fits on the carb just fine and grab a fuel line clip for the carb just in case, i havent experienced any leakage but whose to say it wont. so better safe than sorry. and installing the brass fitting is pretty easy... if you still cant get it ill take some pics of how i did it and post em

ok thanks man i appreciate it and where do i find the bullitin?
