I'm going to try and find some bearings to replace the old ones and then give it a go.

There I fixed it for you.
I take my race motors apart every 2 or 3 races. Open it up, note where the shims go, try not to lose any. Take it all apart, shoot some motor cleaner in there, clean it up, oil the bearings, put it back together - no thread locker on the screws, set the timing.
Getting bearings out can be a challenge depending on the housing - may need a bearing puller.
There are several videos on You Tube that would help.
