"There is no substitute for the correct tool"
One of the most important tools is a flywheel puller. It removes the Magneto housing in the way the manufacturer intended. If you wish to do heavy maintenance or want to get to the bottom of electrical issues this tool is a must.

There are many other ways to do this but most methods are potentially damaging to the crankshaft and housing itself; which is made from soft metal and is easy to mark.
The good news is that this tool is relatively easy to find. I purchased mine for £7.95 from startright.co.uk. Make sure it has a left-hand thread.
If you are lucky you will still have the bike's original toolkit stored away in the right-hand side compartment. (Mine has long since been mixed up with the rest of the toolbox.)
However, if you want to recreate this toolset for on-the-go usage, the contents are as follows:
- 14*10 mm double open end wrench - general use
- 9 mm wrench - tappet adjusting luck nuts
- General use pliers
- Spark plug wrench (including handle bar)
- 0.05 mm thickness gauge - tappet clearance
- No. 2 flat head screwdriver attachment - general use
- No. 2 cross head screwdriver attachment - general use
- No. 3 cross head screwdriver attachment - general use
- Screwdriver handle (for the different attachments listed above)
- 3 mm socket wrench - tappet adjustment
On the SS50E manual page there is a scan of the toolkit pages.
Other necessary and recommended general maintenance tools include:
- Multi-attachment socket set (a good one can cost about £30-£50)
- Feeler gauges for measuring spark plug gaps, contact point gaps and other small measurements (£5-£10)
- adjustable wrenches
- screwdrivers, flat and cross of small to medium size
- pliers, clamps
- emery paper of various grades, wire wool of various grades, for keeping electrical connectors in good condition.
- lubricants such as grease, multi-purpose oil and WD-40
