RE: MOKI LIVES!
Well I ran a little over 2 24oz tanks through my Moki with the Pitts muffler. No complaints and very happy.
I now have it on a MACs quiet pipe and wow! It's now swinging an APC 22x8 at 7200rpm.
From what everyone has said it still has a lot more running in to go.
I've got it in an 87" EF Yak 54.
The pic below is with the Pitts muffler.
