Different tire heights
I have a 2003 Road King and front and rear tires are supposed to be the same. My question is: can I use a stock size 130/90-16 on the front and a 140/90-16 on the rear?

Doesn't the speedometer use the front wheel? If it does, the speedo ratio would be the same, as long as the tire is exactly the same dia. I will gain a little more top end speed but lose a little hp.

Depends on the bike . HD mover away from the front speed cable some time back. Not even my 1996 use it. it uses a senor in trans. You will not lose any HP the change is so small you can not measure it.
