Title: Canam 400 piston
Post by: sleepy on February 07, 2024, 04:03:17 pm

Anyone out there got a 400 Canam Rotax piston they could measure for us? Need to know the compression height and also a center to center conrod length would be handy as well. The piston in the one I'm looking at is out of a Polaris ATV and I suspect it isn't correct as it sticks out the top of the barrel by almost 2mm.

I'll check for you - but most likely the coming weekend.

Thanks that will be very helpful. At this point we are going to try an RM465 piston but will need a barrel lift around 6mm but that will depend on finding out what the stock dimension are. The RM piston works out to be 2mm oversize which will make the sleeve pretty thin but the current is a worn 85mm and there is nothing in Rotax pistons that could be used.
An overall skirt length would help as well thanks.

I think I have worked out they have a 36mm compression height but haven't been able to find a skirt length. If you stumble across it an accurate measurement would confirm things for me but thanks for looking. If your shed is anything like mine you will find it when your not looking for it.
