I had to buy tube benders and what not, make frame jig, raw metal then buy every part new except the engine. I am in 7K in by build just parts not including all the time building and I did 2 frames before I liked it. I have to strip the powdercoat and have it actually painted. I can't count the things I had to do 2 -3 times or parts I bought and did not like or did not fit. f I factor time I am close to 20K.
If I had to duplicate the bike I cold do it for 1/4 the cost and time now that I know what I am doing and how it goes together and what parts to use. Custom frame from straight tubing leavs lots of open variables.
