I believe that the 1st batch of sirios had a bad carb. I bought sirio and I could never get it dialed in. But a buddy of mine bought sirio and his carb is different than mine. Same carb body, but now there's a silver alum. plate behind the mid-range needle. BTW, I tuned his sirio, and that suck is hella fast. It idles alot smoother also.
Is the aluminium plate visible from the outside? And around what time did they stop selling the first batch of sirios, I got mine from tower in december (hasnt been broken in yet) do you think I have the first or second batch?
Thanks
