i know plenty of people building race bikes in sheds that's seem to get along just fine without fancy tools, people have been tuning engines a lot longer than fancy gizmos have been available from the states
A pendant motor and flex drive is hardly a fancy tool, and Foredom one from China complete with handpiece can be had for around £120.
If you want to do 2T cylinders though its very difficult to do much to the transfer ports without a 90 degree tool, and these do cost quite a bit for good ones.
