Does anyone know if you have to get the next step hotter plug after you do the uncorked mods? My 2000 XR650R has been uncorked with the honda power up kit and the plug is really dark as in black. Do you need to get a hotter plug because of the richer jetting? I know there is more air coming in as well compensating for the richer jetting but it seems to me more fuel a hotter plug may be needed?????
