went for a ride today 300k's got to a top of 36ish degree's here a little warm yes
at 2500rpm both plugs were a tanish colour
at 3500rpm left plug was still the same colour while the right plug was allmost black
at 4500rpm both plugs were a tanish colour again
whats the chance of the right hand coil breaking down at a specific rpm?
didnt think to swap the coils over to see if the problem followed the coil besides i had no tools with me to do something like that
