Dan,
F the nay-sayers. Jetting the bike isnt that hard. I'm running 85 jets, with a baffled exhaust.
Those are 18 inch wheels, factory. I got the tires from coker tire, they are firestone.
I got the seat Here:
http://caferacingparts.com/ The seat is pictured on a red cb550. That will give you the correct seat code. It fits the bike perfectly.
I made the licence plate holder from sheet metal. The tail light is a turn signal from a 1979 sportster. I put a dual filament bulb in it, so it works as a brake light. You can get one already like this from "Drag specialities", for like 15 bucks.
Back to the jets, 85-90's work great for a free flowing exhaust. I'd baffle it a little bit, or it wont run right, and your ears will bleed, seriously. The pod's are great, the throttle is really snappy, and you get cool carb noise.
