Yes, leave the #42 sprockets on the M01 motors.  They will
mesh with #41 chain.

#40, #41 and #42 chain are all 0.50 inch pitch.  #41 chain has 
roller width of 0.25 inches but the #42 sprockets are only 0.12 thick.  
A very long length of #41 chain with lots of slack might walk laterally 
off a #42 sprocket.  However short lengths of #41 chain with little 
slack as shown at   http://www.anvilus.com/motor01_tiger_kit.jpg
will not walk off due to lateral stiffness of the chain.

The output shaft of an M01 motor is 11 mm DIA with
4 mm wide key.  You could purchase a #41 sprocket
with 3/8 bore and have it machined, but that would
be a waste of time and money.

With #41 chain, can I keep the same sprockets that the M1's came with (will 41 chain still "roll" on them)?
And the shafts of the M1's are metric right?
