Finished the A-arms today and got the back pivot brackets for the swingarm welded on.
The A-arms should be plenty strong thanks to all the 1/4" thick flat bar I welded in. They're also surprisingly light despite how heavy they look.
As it stands now the front will have just shy of 5" of travel (4.8" to be exact) and the rear will have just over 5" (5.2"). The rear might change if I have to fiddle around with the shock position, but I'm confident about it at the moment. All I have to do from here is weld the shock mounts to the frame and then we'll have a roller! I also bolted the swingarm in and it pivots very smoothly on these huge 3/4" heims.
From here we still have the gas tank to make, rear section of the cage, pedals, brakes, brackets for mounting wires/cables/lights/horn (yes, it's going to have a horn), weld in the floor pan, additional gusseting, and then finally paint (which I want to save as a surprise for the end for anyone who actually reads these updates). I'd say we're 65% there at the moment. Most of the "hard" work has been done.
