You're making good progress- Some known tips- tie the rear of the swingarm with something as it will tweek and rack with that engine, the flangettes won't support it for very long. With that engine -a gear ratio 12t front & 39-40 axle sprocket for descent climbimg and just above 50mph top-end. The intake manifold for that engine isn't available anymore- it's a 2 piece aluminum with rubber tieing them together, with just a uni-filter(no extension) it will bounce without the support of the airbox and crack the rubber very quickly- the more length you have hanging off the end of the carb the worse it will be. The next thing is your swingarm "IS" going to bend from front to rear as the 1" sch.40 isn't strong enough & you've made several welds that has weakened it even more, you'll need to create some type of box/truss to help spread the load out. The next place that has failure written all over it is the cockpit portion of the chassis- you only have the floor tubes supporting the length, if you were to have a hard impact on the front I'd be worried it will fold in half, all your roll cage bracing is on the old nerf bars that don't tie into the floor where the loads would be terminated- this would be true with a roll of this buggy as well. Not trying to pick apart your work- I just don't want you hurt.
