i didnt have the patiance on tuning it.
I had baught the qoncepts kit really at first just for the header set up,to use with the sirio , so I ended up having the kit and no more patiance with the sirio. The qoncepts kit did give me the ability to upgrade my clutch and clutchbell to 1/8 scale ,the motor sits lower ,spur gear and clutch bell mesh better,buggy style motormount, i got rid of the dreaded ez start , didnt like the way it sat on the side of the motor,looks a little cleaner without it ,you can actually take the motor out in seconds.
all in all I have seen what the sirio can do , it is a crazy engine , it screams
I have become better at tuning and I know I could get the sirio running sweet, i have everything to pop her back in ,just having sooooooooo much fun with the wasp ,when it dies , i will definatly go sirio
