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

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

Pair of high quality large bore exhaust header pipes for standard Le Mans exhaust systems. Finished in black and made in Mandello these downpipes have been developed specifically for the Le Mans 1 and 2 and are an excellent choice for bikes that will be ridden

Note that there is no crosspipe joining these downpipes as they are designed to be used with EXA50009. Unfortunately it is not possible to manufacture black painted downpipes with a crossover in front of the alternator due to the production process.
