quick tyre flip for the Helix and some work on the lathe for the Elite fatty

 Used the drill press to release the old tyre from the rim. Quick and easy without tyre spoons flying around...

 And some good leg work...

Voila, back on nice new 120/70-12 rubber

 Made a bearing cup for the right swing arm on the Spacy/Elite. It fits right in a 57mm inside tube.

Had to drill a new hole for the valve on the other side of the steel rim and close the other side. My initial tyre 225/45-10 turned out to have too little clearance to the engine. I'll probably end up using a stretched 150/80-10 inch tyre.
