sort, i guess

but only when i drag the clutch or throttle

if i clutch out with my foot off the gas, nothing happens

if i clutch "properly" nothing happens

if i get a bit lazy and keep tiny amount of pressure on the throttle the noise appears during the point of engagement, not after, but right during.

if i'm driving on the highway and i can "maintain" the noise by getting the clutch to slip just the right amount with clutch/throttle balancing.
