Powerdynamo brings new ignition & light  to your vintage motorcycle

Many riders find that even after they have installed a brand new Powerdynamo ignition that their classic machine will still not start or will barely run.

Consider that parameters other than ignition could well be a possible cause of the problems.

Here a few suggestions (specifically for 2-strokes):

• Always use new fuel. Fuels age quite rapidly, sometimes after a year they will be wothless already.
  
• Thoroughly cleane the carburettor, fuel tank and filters.
  
• Check crank shaft oil seals
  
  If your machine has covered high mileage, isn’t used regularly, or been stood in the corner of your garage for the last twelve months or more then the chances are that the crankcase seals would have hardened and have lost their flexibility at the lip. The springs in the back in the lip will not be strong enough to over come this hardness so the seals will not grab the crank and seal properly.
  Symptoms include poor starting and idling, spiting back, engine starts and stops, poor performance and excessive smoke etc caused by negative pressure pulling oil/air into the crankcase from the gearbox through the suspect seals and the gearbox oil will be lost.
  
  Another simple check is to remove the carburettor from the inlet stub and while kicking over the motor so it is spinning rapidly place the palm of your hand or a piece of paper over the inlet stub and check the suction, if it is very little its time for new seals.
  
• Check the airfilter and the exhaust system . If that is clogged you stand no chance of the engine starting. Paper filters might have sucked in moisture acting as a screen.
