[Roadsters] clicking noise with clutch

[Bubba]

Sounds a lot like a chipped tooth on the drive side of one of the 
countershaft drive gears, or a bearing in the counter shaft.  These gears 
would have pressure on them when driving in 1,2,3, but not 4th, (assuming a 
4 speed trans) but not when coasting, in neutral or clutch depressed.  In 
4th the counter shaft is just along for the ride, being driven, but not 
under load.  The input and output shafts are locked together in 4th gear.
