You have got to get the accelerator pump fixed and when you turn the throttle you should see the spray nozzles spray a stream of fuel into the intake. That thing you had in your hand was a mainjet and mainjet mixer tube.
That pressed in idle jet needs cleaning too - Use a .010 steel guitar string.
I have the Carpy exhaust on mine. tried the stock jets (105) went up to 115 and it runs like a top.
A lot of guys think that a café racer means putting pod filters on the carbs. Don't do it, keep the stock airbox.
If you are intent on doing the café conversion there are a couple of things you need to get right. If you want clubman bars or clip-ons you have to put rear sets also. If you don't it will be miserable trying to ride it. Also, keep the front fender. Cut it down if you want but it does provide some rigidity to the front end and it will also keep the crap from the road from flying up at you.
Don't under any circumstances go hack stuff off of the frame until you know exactly what you want to do with the bike.
do your research on all the parts you want and count the cost. You can spend a lot of money and still end up with a piece of crap.
One thing you should do is change all the wheel bearings, swing arm bushings and steering stem bearings. I recommend All Balls.
