speedo issue -- yellow box from black robotics will correct this problem. Around $100.
noise issue -- make sure the chain has proper slack. The front sprocket will prolly make more noise than stock because it's gotta spin faster now to make the same speed. It shouldn't be extremely loud.

Well the chain I got was 110 links but when I put it on, it was just too lose(more than 1 1/4" freeplay) I wanted to only take one link off, but it seems as if you have to take 2 at a time, so I took 2 off and now it is extreamly tight. What would you do, or what should I do???????? I still have the links I took off.

 

If it's really tight then you're gonna kill that chain fast. You can try reversing the adjusters (aluminum pieces that the bolts push back to tighten the chain) but if that doesn't work then it might be possible to have someone machine 3/8" off of one side (both of them) and that should get you enough slack.
