Using Graphite powder in the Single Speed Tranny and FLM case.

[lincpimp]

Some sort of friction reducing product is a good idea. Sike uses lucas oil stabilizer in his trannys, with sealed bearings. He found that over 50mph the friction and heat caused the plastic output gears to soften/melt. I usually use some tamiya ceramic grease, enough to coat the gears.

Packing the entire tranny with grease would add a ton or resistance and performance would suffer. If you are having success with the graphite, stay with it.
