uh...my book says 54n-m, or 40 ft lbs for the front sprocket, this also converts to 5.5 kgf-m
Axle nut: 93n-m, 69ft-lbs, or 9.5 kgf-m.
for the front sprocket, my manual shows it on pg. 7-8, remember to pay attn. to the units in the torque values! An over-tightened fastener will stress fracture sooner, break easier, or get completely stuck and break upon trying to remove it. In general, a pain in the rear.
Have fun when it's back on the road!
