Rotax 447 (part 6) repairing warped intake manifold

[@clearprop]

Another interesting watch. I can't believe how out of flat that manifold was. Surely it wouldn't have been that way from the factory? Thanks for uploading sir - keep 'em coming. 👍🙂

I’m sure it was straight when new. 195 inch pounds toque on those bolts. The two short bolt areas are barely supported by the manifold, the two long bolts have lots of support. Thanks for your comment

Thank you Patrick.

Is it not straight, true and flat from the factory?

[@RotacRepair]

I’m sure it was straight, true and flat when installed factory new. I believe the basic design of the manifold allows it to warp over time. Thanks for your comment.
