One thing on axle set up is should you tighten the bearing carrier pinch bolts once everything is in place as it should be?
If you ran them loose / out, as the chassis & axle flexes on track would this not allow the bearings to move in the carriers as they might want to and therefore is this not a good thing (excluding potential to develop wear in the bearing carrier - maybe not if also lubricated).
Or if they are tight and the bearings don't move in the carrier the chassis flex / axle flex is controlled partly by the bearing rigidity and is this a better thing??
I think maybe the latter but don't now why?

From cadet days we used to leave the grub screws out from the engine side only (if both sides I think we would have a problem!!) this allowed the chassis to flex a little more and seemed to reduce bog coming out of corners - he seemed to go better like this. If you looked at where the axle passed through the bearing without grub screws you could see a witness mark formed by the lube and the axle moving sideways in the bearing as the chassis flexed, on the cadet it was at least 2mm maybe more, So some thing was going on there, would it work for Junior or senior karts??

Also I used to chase axle freeness, maybe from cadet days - low power, free runing axle might have more affect, used WD40 before every race, had some ceramic bearings once - these were best due to no grub screws, but were also very free running - I never looked into the correct lube for ceramic balls but they were very free running. Now we used std bearings with seals in, very small hole drilled in one seal at the top to squirt lube - grease in and very small hole at bottom to aid cleaning / flush out.
