Novarossi BX S21 port timing.

[Martin Hamilton]

Been offered a couple of unused and good price piston liners for Nova BX S421, or S821 B. 8 port car motor part number 08538 I also have an 8 port case to use these in.Not sure whether this was the same one used in the marine motor or not. Any one know what the transfer & exhaust timing is on these & if they were any good (not to high Timing) as with some of the later piston& liners. Martin.

just about all of the Novarossi motors/sleeve's exhaust timing are around 176-184

the only one that is past this is the new 35plus marine,

cheers Luca

Luca is spot on, on average 180 on exhaust and 127 transfer is most common.
