I have a Honda CR125R 2004 , i tried the NGK B9ES but i found that the motor was flooding the plug and killing the plug , so i am using a higher burning plug which is the NGK B7ES and i have not had any further problems with it

My bike came with champions, but I have always used NGK, then I tried autolite, and I found them to be 10 times better than the champions. Check them out.

My 2002 Honda Cr 125 will not start. After about 20 kicks it makes this popping noise from the exahaust. It has good gas and the carb has been cleaned.

pull the spark plug check if it is wet/fouled,clean and dry it,then ground the pug to the head spin the motor and che the spark to see if you have spar arching across to the electrode tip if it is not and you hear but do not see it and it is sparking within the body of the plug replace it.

I have a 94 cr 125 , that i just bought , it started at the guys house but now wont start for me , tried putting a new plug in , any ideas

Try a compression test first see what it is, next check for spark, remove plug from engine leave connected, ground the end of the plug to the engine and kick over, if you have good compression and spark, it is in the carburation, some bikes dont start well when cold due to bad carburation(air leaks, bad jets etc)you could try roll starting down hill and see if it starts.
