Default Freeing up a drive train

As the topic says, I'm looking for advice, or a process to follow, any tips at all on how to free up my drive train. The chassis in question is a Schumacher Mi1, which runs boosted 17.5. But any help, general or specific to the chassis would be much appreciated.

Hi abec rated bearings or ceramic bearings,
low friction belts,
I used to remove the inside sheilds off my bearings and use a light oil instead of the grease in the bearings.
make sure none of the pulleys are worn at all.

I hope this helps

As above mentioned, I blast all bearings out with motor cleaner and re-lube with light oil (Trinity Royal Oil for me).

I shim out all four hubs/knuckles for slop at the axles while checking smooth rotation of parts by bolting up a wheel and spin it with the dog bone removed from the outdrive.

For pullies pretty much the same thing, check all three individually with both belts removed and dog bones out of diffs. Shim / File off material until they spin free and reinstall belts with right tension (~5mm deflection).

Yep, bearings will make all the difference.
