You furhter might consider that if so, you might have a far larger problem inside your engine; the longer cam-chain will NOT get shorter by dis-connecting the sensor.

You failed to convince me so far....
Hi, sorry for answering so late in this important thread!

You are right! Indeed, the lengthening of the chain shifts the timing of the camshaft backwards compared to the ideal moment governed by the crankshaft/piston. It was my assumption that this amount of lengthening could be neglected, but as said here clearly by Euphonius the ECU's software goes a long way in trying to compansate for these mechanically induced errors. So, I learned that it may not be neglected.

Still, our June 2011 JH600 does not have the camshaft sensor anymore. It may have stalled 2 times in 2.000 km, but I guess more to the very lean mix setting. Will try to set it a bit richer coming spring and see what happens.

Anybody in this forum replaced an "old" chain and what happened to the stalling behaviour? (Did not yet read all posts following this one...)
