A question about spark plug gap. Can anyone please help?
I have a Hero Honda Hunk 150cc motorcycle. It requires a spark plug Bosch UR4 DC which has an electrode gap of 0.8 mm. Now, recently the spark plug was fouled due to excess engine oil in the crankcase. So I had to replace the spark plug. I searched everywhere
the gap on the plug is only important to insure a proper spark to ignite the air / fuel mixture in the combustion chamber... changing to a different part number within the Bosch line means you are changing the heat temperature range of the plug. dropping
