Primary Chain tension Twins

[crm]

I have read that the primary chain tension is adjusted by tone on a running engine.
When the locknut and washers are removed does this not cause oil from the chaincase to be expelled and if so in what quantities - just a dribble ?

In my previous post regarding oil quantities at change it was suggested that at least for triples this can be used as a method to evacuate remaining old oil which cannot find its way to the sump, is this correct ?

Tone thing is a nonsense. Turn and a half to two turns out from tight on the screw. No oil will come out if you remove the adjuster screw on a 750 as it sits in a raised boss in the case way above the hole that allows oil to drain back into the crankcase sump from the chaincase.

Keith, so you tighten it to really snug or just as it start to get tight? In the past (could be bad) I did it while the engine was running like the book said to, seemed ok but not very exact. Scott took the engine apart for the rebuild and he never mentioned any chain issues so I guess there is a little tolerance built into it for the slop adjustment?

Keith explained it a while back as as tight as you can get it with and oily hand on the screwdriver if I remember right.If its to tight it howls a bit with the engine going.
