Are you doing a full system or just the silencer? It depends how restrictive the silencer is.

You can if you want.
Will be fine either way. Maybe a little better 1 size up on the needle jets.

Should be okay just to stick on and see.
Run it for a couple days and see if you can notice any differences.
Do a plug chop after a couple days and see if you're running lean or rich, then adjust accordingly.

it seems to be running lean on standard main jets. going up 1 size on needle jets how do you do that.
