Magneto

Lucas K2F and K2FC magneto rebuilds for twin-cylinder machines. Each magneto is thoroughly tested and comes with a two-year warranty.

We specialise in the renovation of the LUCAS K2F and K2FC magnetos. When we undertake the renovation of these magnetos, we examine the following: 

• Mechanics - Bearings, insulation, washers and shimming of the armature
• Electrics - Armature windings, Condenser, Slip ring, Points and Bushes
• Magnetism - Check magnetism and Remagnetise magneto body
• Ignition - Check Spark strength, Spark timing and stability

We use the CRYPTON MAGMASTER (from the 1950s) to do a comprehensive testing programme on each magneto we rebuild. This allows us to adjust the magneto to achieve the best constant and accurately timed spark that the magneto can produce. 
The final 20-minute hot running test programme includes: 

• Checking the normal spark HT Voltage
• Checking the maximum available spark HT Voltage
• Checking the ignition timing stability over-rev range
• Checking the ignition timing for the correct timing angle (for most twins, this is 180 degrees) 

By performing this test programme, we can be confident that the magneto will be at peak performance and remain reliable for years to come. 
Available for Pre-unit Triumph Twin, BSA A7/A10 and Norton Dominator
