cyclone 1000w reverse direction

[damcard]

My 1000w cyclone (external controller) is setup for clockwise rotation. I can wire it for the other direction, right? If I do, should I get the same efficiency out of it. Having sensors, I wasn't sure. All the threads I find on here address the motor with the built in controller (I did look, but I may have missed it), so I thought I would double check.

I am looking at using it with my racelink and want to flip it around.

I am also ditching the needle bearing 7t sprocket and looking at drilling out a 13t #24 from electricscooterparts.com. I am a little concerned about trying to dimple this motor shaft and drilling out the sprocket. Will it be too hard? I would like to go down to the 11t but am not sure if I will be able to bore it out and still have enough material for the set screws to bite.

Motor is neutrally timed so either rotation direction should yield identical power characteristics.

-Same PCB for the 24V>48V external controllers
-The resistors pictured are just 0ohm links. Rather than the hassle of handling/resoldering them, just bridge the alternate pads with a blob of solder.

It turns out I may keep it in the original direction. I can mount both my sprockets on the right side directly on the jack shaft. It all depends on how the chain line works out. I have a floating brake arm on the other side that limits the diameter of my sprocket. I can easily fit a 80t even a 100t #25 on the outside of the existing sprocket pictured here. But there are a lot of moving parts that I haven't worked out yet since deciding to use my cyclone. Its good to know I have the option of reversing it.

Thanks boostjuice. I may be calling on you again soon when I start modifying my controller. I can't wait to try it with my new pack.
