Just found a insulator 68N-14271-00-00 spacer thing in my friends 2001GPR and I'm about to install VF3's. Does any one think it should stay or should I ditch it? Wouldn't there be a top end performance gain in spacing the carbs out with it?

Also would any one know the difference between the 1200 and 1300 sound suppression box?

Thanks Mike
Merry Christmas to all.
