OFFICIAL SPECS state 8500 rpm so your tacho is just not keeping up with your engine speed.Taz wrote:dunno where your getting the 8500 from, driven a gpx and my gpr and neither have gone to 8500, cut off is pretty much bang on 8250, definitely no higher than 8300 - factory might say 8500 but it aint
I can get to 8250 rpm on my GR easy. So if the GR has a lower cut out that jeans I cannot get over 8k on mine?? I've gone over 8k heaps of times.
