Alternator upgrade kit for Bosch systems containing stator windings, wound rotor and replacement diode board. The superior design alternator has an output up to 300% greater than the original Bosch system. You may wish to fit a plastic alternator spacer ENA18150 if your model does not have one of these already (to improve cooling of the alternator). You will need front crank seal ENA90428 (Bosch seal) if you wish to fit this to a bike with a Saprisa charging system. This kit reuses your existing Bosch regulator and stator plate with brush holder, see ELA29703 for a replacement regulator and ELA17452 for brush holders.

• Outputs 600W @5000 RPM
• Supplied with rotor removal tool
• For tapered crankshafts

1. Remove stator and rotor using the supplied rotor removal tool
2. Remove the old stator windings from the stator plate
3. Solder in the new stator widing wires to the connection block on the stator plate and reconnect the
4. Mount the replacement diode board, this should be protected from the weather but cooled by passing air
5. Connect up the system as follows: Terminals U,V and W take the three yellow wires which should be connected to the stator plate block; Y goes to Y on the stator plate; The brown wires go to earth (we recommend using some earth sleeve on these if possible); Red goes to the battery positive terminal; regulator wiring remains as before (D+ to diode board, D- to earth and DF to brush holder)
6. Check charge warning light is working (earth DF wire at stator to check bulb function)
7. Turn motor over by hand to ensure everything is seated correctly, there should be an air gap between the stator windings amd rotor

Complete electronic ignition kit containing alternator mounted ignition pickup, fittings and amplifier unit. Works with standard 3 Ohm 12 volt coils and can be used to replace points or Motoplat ignition on models with Saprisa charging systems. The pickups for this kit are mounted on the alternator stator. Supplied with instructions in German with wiring diagrams.

2 year warranty on Sachse ignition kits

Eliminates vague timing due to worn distributors on big twins. Preloaded with nine ignition curves, two of which are designed for twin plugged bikes. Once fitted no further adjustment should be necessary. See this link for fitting instructions. Note that if you are replacing a Digiplex system you will also need to replace your 'square' coils with higher impedance 12 volt coils e.g. ELA31165

Complete electronic ignition kit containing alternator mounted ignition pickup, fittings and amplifier unit. Works with 12 volt 3 Ohm coils ELA14500 (big twins) and can be used to replace Digiplex on models with Ducati charging systems where the bike is converted to carburettors. This kit is just an ignition system, it will not control fuelling. The pickups for this kit are mounted on the alternator stator. Supplied with instructions in German with wiring diagrams.

2 year warranty on Sachse ignition kits

Once fitted no further adjustment should be necessary. Preloaded with nine ignition curves, two of which are designed for twin plugged bikes. See this link for fitting instructions. Some bikes may need at least one additional spacer to allow enough clearance for alternator cover to fit once pickup is fitted. Note that if you are replacing a Digiplex system you will also need to replace your 'square' coils with higher impedance 12 volt coils e.g. ELA14500

Eliminates vague timing due to worn distributors on big twins. Preloaded with nine ignition curves, two of which are designed for twin plugged bikes. Once fitted no further adjustment should be necessary. See this link for fitting instructions. We recommend fitting Dyna coils ELA14101 with this kit. If you wish to combine this kit with uprated charging system ELA00502 you will need to make or source longer studs (M5 x 67mm x 2) for pickup, and longer centre bolt (M8 x 58mm wasted). See ACA50001 for distributor blanking plate if required

Brand new genuine Valeo starter motor and solenoid suitable as a direct replacement for Guzzi Valeo and Bosch 8 or 9 teeth starter motors. You may need to fit hex headed neutral switch bolts on some pre 1990 models to make room for the solenoid. Our part number for the bolt is SSA06016
Please note that this item may be fitted to Loop frame models with some modifications as described in Guzziology, also see https://www.thisoldtractor.com/moto_guzzi_loopframe_starter_-_how_to_replace_the_magneti_marelli_starter_with_a_valeo.html for advice on this upgrade.

This is a genuine Valeo starter made in the EU- please do not confuse with the cheap Chinese copies that sometimes appear on eBay.

Complete Newtronic electronic ignition kit containing ignition pickup (distributor mounted) and ignition box. Retains original mechanical advance / retard mechanism.

Kit consists of sensor plate and pickups, magnet, ignition box, clip, screws and instructions. Suitable for all models originally fitted with points which have a mechanical advance / retard . Can also be fitted to Strada 1000, Spada 3, Cali 3 etc... if the distributor is swapped for a points type part with advance / retard mechanism. Coils should have 4 Ohms resistance on the low tension circuit, OE coils will work OK but you may see improved results with high performance Dyna coil ELA14101

Developed from the original Piranha system, Newtronic ignitions are contact breaker replacement ignition systems covering a range of Japanese and European motorcycles from the late 1950's onwards. Using contactless, maintenance free, infra red triggering the Newtronic ignition has gained a reputation for ease of installation and effectiveness from satisfied motorcyclists around the World. The switching units include an integrated timing LED for each channel, making it quick and easy to accurately time each cylinder independently (an essential step in gaining the best performance from your engine.). The system typically consists of three main components:

1. An ADAPTOR plate which mounts the lamps supplying the beam of infra-red light. This is broken by the ROTOR as it rotates on the engine cam or crankshaft. When a beam of light is re-made as the rotor blade clears the beam the switching unit is instructed to fire the coil (please note some systems will have separate mounting plates for each lamp and will not be assembled on a single plate as shown.) In many kits these are supplied as 1 lamp per cylinder. Other kits use a wasted spark system with 1 lamp firing 2 cylinders. The adapter kit also includes the parts needed to fit the lamps around the motorcycle cam or crankshaft - usually supplied as a base plate and /or segment plates with pre-mounted lamps.
2. A ROTOR which fits on the bike cam or crankshaft and makes and breaks the lamps infrared beam when the coil is to be fired. The rotor may be made of metal or a heat and solvent resistant plastic.
3. A SWITCHING UNIT which collects coil firing instructions from the rotor traversing through the lamps and fires the coil. The switching units are supplied positive or negative earth depending on the bike configuration and have a separate switching channel for each lamp in the Adaptation Kit. 12V and 6V versions are also available especially for earlier bikes. The switching unit has an integral timing light for each coil and is fully compatible with existing systems to the older design. It is also a direct replacement for Piranha switching units.
4. An INSTALLATION WIRING LOOM is supplied with each kit, tailored to the original bike loom dimensions, connectors and wire colours for a quick, easy and professional looking installation.
