30years Posted December 21, 2010 Report Share Posted December 21, 2010 I am wondering what it means to do a plug chop? Anyone help? Quote Link to comment Share on other sites More sharing options...
Jereme6655 Posted December 21, 2010 Report Share Posted December 21, 2010 doing a plug chop is how you tell whether your bike is running rich/lean. you warm the bike up on the old spark plugs and once warm you install new plugs. then you make a full speed run.....1-6th gear. When you top out in 6th you want to pull the clutch in and shut down the motor and coast to a stop. then install your old spark plugs again and take your new (just tested) plugs back with you. what you want to do it cut the threaded ends off the tested plugs and look for the carbon ring that is on the porcilan segment of the plug. you want it to be approx. 2mm in depth from the base towards the electrode and have a light brown color (much like the color of a carb board box). If it is too white then your bike is running too lean.....too dark and your bike is running too rich. running a bike too lean will cause premature failure while running it too rich will cause a loss in performance.

30years Posted December 21, 2010 Author Report Share Posted December 21, 2010 Thanks alot man. I'd never heard of chopping the threads off. All I ever did was install new plugs and look at the bottom of the plug to determine if it was good or not. I'll give it a try. thanks Quote Link to comment Share on other sites More sharing options...
