When you think about it, pretty weird to do the tuning for idle (and 
4000 rpm without a load on the engine is barely cracking the 
butterflies open either). Tuning should be for running conditions, not 
for great idling; tuning for idling is only a proxy for running. Best 
to use dual vacuum gauges (or far second-best, the 9v TwinMax) and go 
riding to check/confirm the idle synch settings.

For sure, you don't want any uncorked leaks into the maninfold! If the 
fume-inhaler has been excised, install a cross-over balance tube rather 
than the caps.

BTW - this list is really lucky to have David Paulus join us. He brings 
a cracker-jack knowledge of automotive engineering combined with much 
real-world experience. Nobody should casually disagree with him but.... 
I just finished an Expert Witness report for a little girl plaintiff 
who was injured riding a bicycle that was too big for her. With 
masterful technique, people like David can manage a tall bike but 
that's not the same as saying it is a good idea to have a bike which is 
too tall. I always admired the briefly offered R80ST which combined 
features of the GS without overdoing the off-road-ready illusion.
