The only place I find parts for the Mega engine is at Ashford hobbies and he list the part as I show below.
He is not very willing to give much help as I have emailed him with no responce.
On his site he list it as (ABC-Set ZX21 w/insert DSII) he also list a rod (Connecting Rod ZX21 DSII+).
I have a rod already I just want the rest.
The pics I see of the DSII Race are the same sleeve as my motor I am just not sure if the DSII is the same as the RACE or + version.
I have checked the rod I have it has a 4mm small end so from other post I have seen it is the newer version.
