SANDSTAR Posted August 22, 2005 Report Posted August 22, 2005 Stroking an engine is not a reason to change spark plug heat ranges. Quote
momo20 Posted August 22, 2005 Author Report Posted August 22, 2005 even though i did i port and polish on the jugs, stoker crank with stoker pistons...what would be the case in changing the plugs colder or hotter Quote
SANDSTAR Posted August 22, 2005 Report Posted August 22, 2005 Stuff like really high compression bikes that run at higher temps than a normal engine like yours. Nitrous is another reason to switch heat ranges. If you run a colder plug( which means that the plug dissapates more heat) you run the risk of creating a fouling situation because the plug insulator cannot stay hot enough to burn off deposits. Remember- plugs do not create any heat by themselves. They DO dissapate heat from your motor at diff. rates. That is what the heat range really means. Don't get any bright ideas about trying to fix jetting issues by changing plug heat ranges. That wont work. Quote
momo20 Posted August 22, 2005 Author Report Posted August 22, 2005 thank you very much...that cleared up any questions that i had....so i am gonna stay standard or normal heat range....thanks a lot SANDSTAR....your the man Quote
