Back to the wonders of my R1oT and the pending engine (re)installation.

Has anyone heard of any bad (or good) experiences with the Westfield XTR2 engine installation?

Basically, Westfield rubber bush the engine cradle, quite tightly there's little compliance, but compliance there is. They then rigidly mount the differential cradle to the chassis. Therefore the engine can move (minimally), but the differential can't. Have you any experience or heard of any problems related to this set-up?

To me, it seems the best of both worlds, the only fear I have is the chain getting slacker than it should under heavy acceleration - or am I being totally stupidly worried?

Contributions *VERY* welcome before I start welding bush tubes onto my engine cradle.
