JawaMoped - Technical

My 1992 Jawa “Jive”, two speed, kick start, model 225.
I bought this off ebay with only 305 Km on the clock.  It is a restricted version made for the Netherlands market, where the yellow plate on the front mudguard was used as an identification marker. A yellow plate identifies it as a (normal) moped - restricted to 45 km/h, helmet required.  An orange plate was used to identify light mopeds - 25 km/h max., no helmet needed.  These plates are no longer used, replaced by yellow or blue rear registration plates respectively.  I’ve no idea how this ended up in the UK. This is badged as a Jive but all the UK literature on these models show the Jive as a single speed pedal start.  This kick start model should be a Jazz, unless this model was badged as a Jive just for Holland?
I’ve done a bit of restoration - refreshing the paint work, the white in particular, some of which had yellowed badly, and generally cleaning and tidying it whilst keeping it completely original.  The only changes from original that I have made is to remove the 28 mph restriction and add a horn and stop light, required for the UK MoT test, and a mirror. More information on these additions is in my ‘Electrics’ data sheet, below.

Below are some data sheets and articles on various aspects of mopeds, some with information on tuning. Some of the articles are by me and some are by others, but in all cases you are advised to seek professional advise before doing any modifications to your moped unless you are very sure that you know what you are doing.  I can take no responsibility if it all goes horribly wrong.

I regularly get asked about availability of spares and about the value of mopeds.
I have prepared this data sheet that tries to give some answers.

This data sheet has full details of the Babetta electronic ignition systems and the various electronic units used, including how to swap to later, better versions.

Full description of the lighting and auxiliary equipment and generator fitted to the Babetta mopeds and some notes on modifications.
