    Rotax 2 Blade Head Gasket

    Does anyone know how much cylinder pressure or compression would increase by going to the 2 blade gasket.I want to bump up the comp on my engine a bit. I think they are .7 mm thinner than the 4 blade standard one.Would be thinking would need to run the Rotax cam chain tensioner with this aswell!!!

    I believe it is anymore than 0.5mm that you will need the rotax chain tensioner, not sure how much difference it would make to comp though. The rotax 2 layer gasket is just the OEM gasket with the 2 middle layers removed. You can drill out the rivots on the oem gasket and remove the 2 layers to save some cash.
