Yes its white/yellow/cream coloured on the tooth, but once you've heated it up and scraped it off, it could well be black/grey/manky......

(i ran my B4.1 with grease on ALL the gears, its still going strong now.)

I thought it could be tooth wear of idler and diff gears, and to some lesser extent the metal layshaft gear, but there was far more powder than wear to the teeth.

How much and what type of grease did you use? how was the gear wear when you next stripped it down?

So what's the general consensus on lubing the gears in the transmission, and what's the best lube to use? black moly grease? silicone grease? lithium grease? some oil? or running dry, like the manual indicates?

It wouldn't surprise me if they said to run it dry, and if it causes excessive wear. it sells parts...
