Since a lot of people on this board have inquired about the proper technique to rebuild a salvaged bike, I will hopefully illistrate this effectively so that everyone has the proper tools necessary to build a bike.
To dispell a couple of myths about rebuilding a bike: You can get full coverage insurance that will cost the same as a "clean title" bike, insurance replacemnt value is not affected, resale value isn't hurt too much compared to cars, and there will be more as I take you step-by-step through this process.
So "What do I got to do?" you say? Well lets start with step one then
STEP 1: Find your bike!
This may seem simple, but you have a couple options when finding a bike. Klodes Auto Auction is one place, they charge a 150 dollar member fee, but have a lot of selection to choose from. Lincoln Auto Salvage has a smaller selection but you can find good deals there, this is where I bought my 636. Or private party's or dealerships will sometimes have bikes ready to rebuild.
For me, I found my bike at Lincoln Auto Salvage. The bike had mainly cosemtic damage, the subframe was tweaked, but the bike was relatively "solid" so I made an offer of $2700 and took it home. Things to look for before buying a salvage bike: bent frame, wheels, forks (these are high $$ items) leaks, condition of seals, strong running motor, pretty commons stuff but you defiantely don't want to overlook any of these areas or it will cost you during the rebuild process.
