Sorry to thread - jack but is there anything particularly bad with using a bpr7es plug on my fireball? I haven't fully tuned it up yet and I'm not using a power arc, but a trispark. Everything seems good but I don't want to damage anything! Pardon my ignorance..
Thx dude, my bike was run with bp7es before I git it by PO, so I just got a resistive version to go with the trispark, I will sort it out! Thanks
