Yay finally got the cat and fiddle an wet cheshire test ride onboard edited dried up a bit by the time we made it to the cat was cool seeing how the 650ss handled in the wet superb chassis meant just as good as in the dry. Few things to sort this weekend after I fix my uncles gt750 tomorrow. Think the whine is of the timing chain so need to check that. Is the mag one tensioned by the same tensioner for the cam one? Gonna go through my manuals in the morning. Couldn't hear the timing whine clearly till we sorted the rocker spindles an primary chain. An need to fit the new springs I've ordered for the outer gearbox cover if they show up before weekend. Exciting though that the carbs are settling in along with the rocker spindles.
