do you leave the wires that go to the thumb throttle unconnected?

how short is the 450r throttle cabe will there be enough cabe for a 1'' or 2 '' riser?

i have everything on the way right now i just need to know what to expect when everything gets here.

and will the stock 450r jetting work off the bat or does it have to be changed right off the bat????

thanks for the info
