do you use the 2611 pipe?how many minutes it can make?
did you changed the rod after the run in?
where is his power band?it is like the others sirios?high rpm style?
thanks !
I have the Sirio XXX. I have only run the 2611 pipe (older version). I am still using the orginal rod as they seem to last the way the Novarossi rods do.
I have not had a problem making 5 mins yet but it doesn't get the mileage that the IDM engine gets.
This engine seems to have a more broad power band. It still has good top end like what we are used to, but better bottom end than some of the earlier Sirio engines. I do have a good clutch setup that seems to work pretty well.
