550 has different rubbers to 500, there was a member on the US forum that was making the 550 rubbers otherwise they only come with the plenum chamber if its available

Sorry 550 K3 is different as it has PD carbs

I should clarify Bryans comments. It’s only the 550K3 which has different intake rubbers than the 500, the 550F has the same as the 500. It’s due to the different carbs fitted to the K3, which were PD carbs. The 500 and 550F share essentially the same carbs.
