Does anyone have trouble keeping the spark plug cap on the plug when racing. when i go over a really bumpy place really fast, the cap falls off and I am dead. Is there any special boots that racers use to keep this from happening?

Just wondering.

 

It would be a good guess that you have a plug with the cap on the end off. Does the plug end have threads showing? If it does you then need to change the plug cap to match or put a cap on the end of the plug. I thoink that this is your problem. New plug caps cost about $4-5 or for the good NGK cap about $7 at the dealer.
