[QUOTE="David Trustrum, post: 743499, member: 21529"] Eek! Unless the piston is incorrectly marked the arrow should be to the front, either way the ring pegs should be to the back. What I would have thought inevitable if the ring ends find themselves in a large port they will poke out & do some makeshift porting. I guess it would be possible if the pegs were over a bridge that it might survive backwards. I have seen pistons with a single ring in the middle of the back crossing over a boost port (Rotax), as this is central & doesn’t twist it seems to survive. There are other reasons for the direction of pistons like offset of the piston pin & more obviously holes in the back of barrel reed valve engines. I have not taken my EC apart yet so I can not comment on the piston itself. One thing I did notice on my GasGas trials bike was the ports were a little on the crudely finished side, how do the enduro ones look? [/QUOTE]
