Virtually everything I have purchased to fix up all my bikes came off eBay. Working with eBay is a skill like anything else. I have my saved searches fine tuned and when the right item shows up at the right price, I'm ready. I have a 280+ purchases on eBay and a buddy was asking me how much I've really saved. Well aside from the sales TAX that you save almost every transaction, I went back and looked at my records, look at some of these purchases for the busa:
Power Commander III USB - $152, retail $300
OEM Gen II mufflers - $1, retail $2150
Forks - $180, retail $2200
Perfect 2006 tank - $210, retail $785
K&N air filter - $28, retail $80
Wave rotors - $184, ? ? ? ?
All Sintered pads - $45, retail $100
Racing levers - $48, retail $190
Adjustable rearsets - $148, ? ? ? ?
Rear footrests + rear calipers - $91, retail $420
Steel rear brake line - $11, retail $50
Clutch Master - $41, retail $164
Headlight - $132, retail $265
Inner fairing plastics - $32, retail $145
On second thoughts, maybe you guys should stay off ebay, less competition for me!
