I run that motor, at first I could not get a good tune, but found that the plugs I was running was the problem it runs great now with the sirio 2057 an a os. 8 plug might not be the best plug but its working, an make small adjustments. As far fast, its very fast no problem with speed

from what I am seeing with my Sirio is that it prefers hotter plugs....

great engine...dont listen to peoples plug choice...i found with my rossis that they like the o.s. 8 but with a turbo plug they like the p3...run the plug that makes ur engine run
