Reading 9000rpm and they advise to fit a 7afe headset to the silvertop to raise compression to 11:1. But which year and which gasket as bnt have multiple ones listed.
I know the South African guys use this and I still can't work out how it is that the pistons don't hit the head. However to go to 11:1 you just need a TRD 0.8mm gasket. I can supply one if need be for $120AUD
