Vigor CS CCPM
KSJ 2p Muffler
2 Gallon Break-in
During Break-in I hardly could wait to really put the 91 through its motions and start hitting some hard 3D with my new Vigor - Right away I started to notice that the KSJ muffler likes to spin around and around. Not a real big deal just a bit uncomforting.
As I started to tune the needles I started to notice that the Vigor started in to a tail vibration that had me very worried. Worried for good cause as screws and bolts started to back out and fall off. Going just a click or two leaner makes the 91 very mad so I backed off going to the rich side, only about 6 clicks and it smokes like a chimney. I don’t have as much power as I do closer to lean but the vibration is not as bad.
I have ordered a new shim and a new Zimmermann Pipe and hope to try these out in the up coming week. After talking to other people that have the same set up, and who have tried to shim and have changed to 15%, they still stay they have not seen a change.
I am wonder who else has this problem with the Vigor / 91 and what they have done to fix it - I DONT EVEN WANT TO FLY right now and this is very disconcerting - I love to fly and wish now that I had a Nova with an OS 61 -
Please if anyone has any feed back I would sure love to hear it -
