System 72 95 999 20
=> €/$

generator / ignition system
for Yamaha XT 500 , TT 500 and SR 500   with twin spark coil
For better starting properties of the Yamaha and on explicitly customers' request we have changed the rotor (now: 1.1kg or 1.4 kg/ 112mm diameter / 180W - previously: 0.7kg / 103mm diameter / 100W). 

To the older version (system 70 95 999 00) with the lighter and smaller rotor.

same as 72 95 999, only with twin spark ignition coil (see info)

Magnet based generator with integrated solid state ignition. replaces all original generator and ignition parts. Updates your system to 12V/180W DC. There is no need for changes on engine casing. The system is technically capable of running without battery.
advantage over original system
  • all parts are new
  • solid state ignition
  • more light output (use bulb 40/45W)
  • very stable ignition with solid spark
  • better starting, better fuel burning
  • no trouble anymore with setting points or the old electronic ignition (depending on what system you had)
  • no wear anymore on collector, points and govenor
NOTE: Installation of the new system does NOT make instructions from Yamaha on how to start the bike without violent kickbacks obsolete. The new ignition does not eliminate this inbuilt problem. 

also know that the new ignition coil does not directly fit  on the stock coil frame.  Find explanation here. We are quite willing however to produce and add some adapter piece, but presently lack dimensions. all info is welcome
