I normally run a BR8EG in my 03 cr250. I am going to be doing a lot of jetting changes soon and dont want to go out and get a bunch of expensive plugs to do my plug chops. is there a cheaper plug I can run while I figure out all the settings?
Don't buy them from a dealer. I was paying $7 for a BR8EG until I called NAPA. They sell them for a little less than $3 a plug. The dealers seem to be doing a little price gouging.
Nope, you can't get an accurate plug reading from anything but a new plug. If the plug is already colored you have no way of distinguishing between old and new. People assume that all old deposits will burn off, and it's just not true.
