[83interceptor75]

I just picked up my first bike a week ago, it's a 1983 honda v45 interceptor vf750f. she is beautiful. I just cleaned out the carbs and bought some new plugs for it (the past 2 owners have let it sit so carbs were dirty and plugs were most likely fouled...). anyways...I'm just looking for a place where i could find like an air filter for it and a ignition button (previous owner wired ignition to the dash w/ a push button and its awkward to reach over there...i want to wired it back so im just looking for the thumb buttion and whatever else i'd need to mount it on the right handle bar...any ideas???) I'm basically looking for an online store that carries that stuff or something...i've looked on ebay and i've just found random parts, none of which i need...any help is much appreciated, thanks!

...ill try to attach pics the bike...
on an unrelated note, i was just curious my cap on my engine is black and not brushed like most of the pics on see of the 83 and my exhaust is black then brushed metal...just wondering if that is at all stock...supposedly the bike is "all original" but i've already found a few things that aren't so i woudln't be surprised...thanks again.
