Good lord.
Ok. Everything is estimated or rounded.
My cb650 project:
bike- $450. I was so broke and the time, the guy let me make
payments on it.
carb rebuild set 1- the keyster kit- $120 ($30ish each)
that set leaked like a freakin sieve.
Honda set- $40ish each, so closer to $160.
Accelerator pump- $15
Air cutoff valves- $10 each. (x4..) $40
Tires- $60 each. $120.
Gasket set- $86
MC rebuild kit- $40
MC reservoir- $35
Pads- $15
New clutch lever- $5
All new cables- $30 give or take some for clutch, speedo, tach, throttle. $120
Cost for Mac's Radiator to boil out, coat and completely effing hose my original tank- $200.
New tank- $100. (lousy learning experience.)
H4 headlight kit- $50 (ebay, claims to be DOT)
Seat recovered- $60
Kickstand shortened- $20
Shorty shocks $60
Progressive springs w/ fork oil $70
new seals/dust seals $20

Accel wires and caps- $10
4-4 exhaust $200 (I think?)
Hard luggage- $90 (ebay)
Fiberglass kit to repair luggage- $15
Windshield- $90
I think.... that might be it.
comes to $2599 all told... a decent deal for the bike as it stands.

I don't keep track of expenses though, all that was spread out over 3+ years, too, so it wasn't as painful as some builds.
