I work over here at tousley motorsports and that is a fairly common plug in bikes and stuff so we always have plenty on hand too. They run $2.69 per plug if you come in ask for Nate or just tell them the plug number cause the parts guys can be stubborn if you tell them it is for somthing other than a bike or sled.
first time gapping spark plugs, should i do it alone?
NO, definatly not. Make sure you are wearing protective head gear like a bicycle helmet. Also make sure there is someone there who can give you a ride to the hospital in case of radiation exposure. [/heavy sarcasm off]
i got my air/fuel guage from slowboyracing. auto meter phantom is the only way to go. i just thought id spend 25 bucks and not 85 on the same exact blue wires that make sparks.
