Hi All,
I have just fitted another engine in the Sporty and I found this vibration around 3000 rpm when coming back to idle, you don't seem to feel it as you take off and all the other the other rev rages it is smooth, it is just around the 3000 rpm, the old engine never had this vibration that I have now which seems so strange to me, same prop.
Dieter the L2 has checked everything else and now it seems to be this balance issue, so to eliminate this and hopefully fix it who is the best person to get this prop balance done and how much does it cost approx?
