Just bought a slew of stuff from Cyclemax, and noticed my CompuFire alternator is somewhat hard to spin. I would think it would free wheel like a motor does. But it certainly has resistance to it.

Is this normal? And I suppose it will free up as it gets some miles on it...

I would expect it to be reasonably tight with new brushes and not being worn in to the armature yet.

Besides what Rudy has mentioned, you'll notice a slightly different sound to it as well, compared to your OEM one,once you have it running.

Rudy is right, the Compufire doesn't spin easily by hand. Nothing wrong with it, they are all like that.

Got it, thanks guys! Figured I would ask rather than put it in and wonder why it runs so hot or noisy.

Now if this wonderful weather would just go away so I can work on my bike rather than ride it!

I just finished a test run on the new Compufire alt for them in Dec. When I put it on in Aug it was very tight, hard to spin by hand also as your is. It has preformed very well that way. Enjoy it bro, still great product and great peeps at compufire, most all ride, mostly Harleys as their main products are Harley beefed up starters, and all other trick electrics.
God Bless,
Stu

When new, the shaft seal at the front has a pretty good grip on the shaft.



Also, of minor consequence maybe, but it has a larger rotor and stator and while all that makes more power, it also gives extra leverage to magnetic pull.
