I really appreciate this video! My son is on an older chassis, and we have been searching for any ways to find another year or so out of it. We made huge gains over the summer, but I was sort of at a loss of where to look next to keep moving forward. This was exactly the sort of thing I needed to begin making my list of things to tackle next.
Everything you listed will slow a kart down, but anytime a kart will not respond to changes made to the kart first thing I check is the frame rails and if the chassis is sagging, a chassis should have a 1/16 to a 1/8 of arch checked under the seat bar with a straight edge along the main chassis rails, the cross bar where the bottom of the seat is mounted is where you check for arch or sag. Lots of karts sag brand new, ever wondered why you’re new karts a turd this is why, so check for a sagging chassis before you buy, a chassis can be arched on a frame table but don’t do it if you don’t know what you’re doing, take it to someone that does.
That's a great point that I've never heard discussed previously. I've often wondered if kart chassis are cambered and, if so, how you could tell if the camber was correct. Is the arch you mentioned measured with the kart unloaded (no driver)? I'm assuming you'd measure it with the kart supported on it's tires, or, at least with it supported on the axles where the tires would normally be?
@@mattjohnson1148 Matt I have never seen a kart chassis it’s self have camber unless something bent lol, when I have checked for arch or sag of a chassis at the track I take everything off the kart that gets in the way of the straight edge, kart is unloaded. You most likely will not be able to arch a chassis at the track without a frame table, I have seen a few guys try before though lol I put 1/16 to a 1/8 of arch in a chassis, it depends on how much the kart with driver weighs whether 1/16 or a 1/8 of arch is needed. A chassis sags when the driver is sitting in the kart, you still want a little bit of arch in the chassis with the driver in the seat. I have checked on a frame table with the driver in and out the seat to see how much arch the chassis has with blocks of wood measured with calipers so I know exactly how much chassis arch is needed.

Can you link the Facebook page of the videos you posted?
