Just a thought as a retired engineer, i would raise that hoop that attaches to the bottom of the shock by 1.5 inches as at the moment the hoop and shock unit are in a straight line. When you have tank/seat/fuel and body weight on the bike the whole suspension linkage will be bending down which will increase the shear value on the welded brackets. Start off with the suspension at a raised angle so that it will become more linear under load. Hope you don't mind my suggestion as otherwise your concept is good.
You beat me to it. I agree with this solution. If the bracket welded to the swingarm hoop could be parallel rather than perpendicular it would drastically reduce the likelihood of failure.
WD-40 works well as a cutting fluid on aluminum. Also climb mill aluminum when possible. Chuck the cutter as far into the collet as practical to increase rigidity.
Congrats to all of us for beeing able to enjoy your build. I have an old airhead. To be able to follow your thought process with design and fabrication is quite the trip. Thanks.
Lots of reinforcement in that area from the lower frame attaching on either side, and even the front gusset. The frame itself is oversized as well. I would be shocked if anything bent due to normal riding.
I think he’s concerned the mount at the top of the shock will punch through the blank at the end of the backbone. Me too! It feels like there should be some extra strength in there. A plug would be good.
I a no mechanic nor a welder so I might be talking out of my a** But I’m a bit concerned about the perpendicular tabs on your added swing arm part. Where the bottom of the shock is bolted to. What I mean is, when in stress, the force of the shock will want to rip your welds. The whole contraption essentially doing an S. If you keep the shock, tabs, and added arm in one line, it’ll only press down on your welds
I can't wait to see the finished product. I wonder if you could attach two wires to the battery that come out under the seat or somewhere that's easy to access.... to be able to test your battery voltage and charging system without taking the tank off. I'm kind of OCD about checking the batteries on my bike, so having to take the tank off every time would be a pain...or it would cure my obsessive compulsive battery testing. : )
Aha I wandering how you were removing the shock mount hoop if your welding it solid to the swingarm pivot tube. I figured you'd weld some mounting tabs on the pivot tube and crossbolt the upright brace like the other 2 bolts. That system you came up with is pretty neat.👍
I don't know that I would put much faith in one M6 bolt to absorb the full forces of the rear suspension. But it's a good way to make something (not so structural) removable.
love your channel you’re inspiring me to start building/flipping motorcycles, any must have tools for someone starting out, or even just some tips? the fabrication side of things i pretty much have covered I’m a weldor/fabricator by trade so i have a tig, mig, plasma cutter, bench grinder, grinder and other miscellaneous fab stuff, i’m only 23 so i’ve only built a couple dirt bikes so far and really only buy tools if i run into the problem and don’t have a solution lol. any tips would be appreciated, keep up the nice work!

Awesome mill work with that tray! Fancy looking!
Nice project. Another consideration. I've seen batteries short and catch fire. Scary near fuel tank.
That may fail compliance. Food for thought dude.
Hey Taylor, happy to see you cracking forward on the airhead! Nice work on the mill!

Nice job machining the aluminum battery box Taylor. You have lots of big tools.

Really liking this build. Appreciate how you break things down and relate what you are doing. It's the details that make the bike.
Methinks you need a slug in that backbone where you mount the upper shock…a lot of force generated there.

Digging that battery clamp man 👌
Sweet battery tray
That APP is pretty handy too beats calculating surface footage to attain rpm then feed rate in inches per rev manually.

I used to have a quick connect under the seat for plugging in a trickle charger. Would work perfectly for what you want.
@@outerfroggy1 same. I use one of those pigtails for a Battery Tender.
Nice build. How about adding a AMR 500 supercharger.

so glad I found your channel homie, this has me thinking I could weld and fab my own shit :')
looking good, great work.
what the heck is that little trick part!?! and where do you find them.
Is the regulator rectifier from motogadget as well?
So when you want to service the battery on the side of the road, do you have to remove the gas tank?
Magnificent 👏
awesome
Awesome!
👍😎👍
