Agreed with the lead. At one time lead had a real advantage over lightweight as the lightweight shrank and cracked easily.
Most lightweight problems that are quoted are due to improper use or prep. Bondo needs nearly as much prep work as lead, IE clean dry slightly roughened substrate, but many people fill a dent without even attempting to smooth ot the panel or washing the surface, going right over paint and often wax, then say bondo's useless because it falls out. bondo is best in thin aplications, thick gobs of it will crack. I've seen professional jobs with bondo over an inch thick on cars.
Back to the bike, was looking at that again, to see if there were any bids on it, and noticed that the guy 'capped' the frame where he cut it so it 'looks' finished. May just be my own work ethic or my idea of eye appeal, but if he was going to go through the effort of making the tubes look nice at the cut, wouldn't it have been easier to remove the tubes all the way to the down tubes at the front, and shorten them a bit more at the rear? the only reason for the rear to be as long as it is would be to use the stock airbox mounts, with the pods there's no need for the tabs. as it is you have those 2-3 inch stubs hanging out doing nothing but make people say huh?
like someone else said, good parts, halfway decent ideas, but just put everything together wrong.
