N9 Bad vibes

[ROSSCO]

Hi Paul,

Yes!, that's the new SE Center Block for the N9. Did you order the step washers for the rear gyro bracket also?

If not, these are the washers you will require as they press into the mount:106-930 M3 Step Washer

The engine runs well, well it seems to, its about six month old and had about 2 gallons through it, I didn't know about the se mountings will get some sorted

Finally got it sorted, had one of the lads from the club have a look and found the problem straight away, when we turned the engine over by hand the clutch bell was lifting very slightly, so stripped it down and started from scratch, centred the clutch on the hub with 0 run out and also got the top of the shaft to 0.5 thou

not flown it yet, but did run the engine up and it does seem 100% better

Excellent!!,... Let us know how you get on!
