Welcome! It does take the 400 some time to break in the engine. I thought mine was gutless until the 200 mile mark or so. Then it was like a totally different engine. So, I had that knock too, and don't anymore so it is nothing to worry about. Also, the Arctic Cat tranny is a really good one, you won't have any problems with that either. Enjoy your maching and put some pictures up!

Great machine, as others said it will wake up some. I haven't heard of many problems with this model, tranny or otherwise.

I gotta say, when we first got our 400's I was under-impressed with the power. But I figured who cares. We're not racing anyway - just "touring".
Well, now that I've got over 1200 miles on mine and my wife has about 900 on hers, what a difference! I can now 'gas on it' in the turns and actually break the rear tires loose. It climbs anything and goes anywhere. I can't believe the difference once you pack on a few miles.
I'm totally impressed. No problems other than stuff I've caused myself.
