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....

You definitely do not need a "tuned" version of the engine. Plenty fast from Sirio. I am using an ultra hot plug in mine with a Sirio 2013 pipe. Runs well at 200 degrees and idles forever. I think it's a great engine.

Nevermind, guess I should have followed your link before I typed. I was thinking an aftermarket company was "tuning" it.

Yeah, that motor will be a good one.
