Ngk spark plug gap chart

usually around .028" - .032"..

r = resistor
b=thread size = 14mm
7 = heat range - NGK, the lower the number the hotter the plug. Other mfg. are opposite - higher number=hotter
h = thread length =1/2"

These are THE important ones... the rest are mfg. specifics

What,s the reason for my honda crf 100 sparkplug getting so dirty all the time i need to keep cleaning it to get it to fire everytime can anyone assist on this problem please help????????????????

The bike may have the wrong spark plug in it. The stock plug is NGK, CR7HSA. You may want to go to a hotter plug > CR6HSA. It is also possible that a prior owner installed a bigger main jet. Check the main jet size. The jet will have a number stamped on one side. Stock is #92. A #98 jet would be a richer jet. Please rate my answer. Thanks.

2006 crf100 no spark

You have 2 basic possibilities,
  • A kill switch is active
  • The ignition control module has gone bad
The stock spark plug is an NGK CR7HSA. Is a kill switch on? Does the side stand have a kill switch? Is it working properly? Check the operation of all kill switches with a volt ohmmeter.

Check the wiring harness. Did a wire come unplugged? Are all wires clean and with solid connections? Any abraded or pinched wires? If still no spark, get CDI system checked at the dealers shop.

A top rating on this answer? Thanks!
