    So I was riding my am6 and I was thrashing it was only riding for maybe a minute then at full speed it locked up I grabbed the clutch and coasted to a stop I selected what I thought was neutral but it turn out I was in some sort of false neutral so I rode home really low on power thought I was in 1st I was actually in 5th?i got it home expecting a soft seize but the compression is brill gears select except form time to time I’ll hit a false neutral It has full power and rises perfect I will note as it locked up it shot coolant out the cap on my leg,wondering if anyone has had a similar thing happen I’ll inspect the top end when I can but it revs clean and lots of power so doubt it was a seize I was thinking I had shed a tooth but the gearbox seems okay

      @declan the AM6 engines are notorious for their false neutrals.

        Yeah my Aprilia had neutral in every gear.

        Have had this happen before on both the YZ and the Aprilia. Both for different reasons, but all down to tune.

            @declan Yeah. The YZ was being cooled too much and seized. And the Aprilia seized due to detonation.
