Wife and I just picked up a 2014 and so far are loving it.  Just trying to find the best places in Colorado to do easy rides as I have a disabled son who has his own ATV to follow along.

Not super fast or quick off the line but love the ability to just cruise along.

I am wondering what mods can be done to give it just a little more umph on take off.  I have taken it up to Painted Rocks, Badger Flats and Rainbow Falls so far.

Welcome. The 600s like the secondary clocked to C1.

Welcome, awesome that you are able to get out with your son! 

I'm not familiar with the 600, I would suggest prior to any modifications or changes you make watch the RPM. Get a good idea of engagement & shift rpm prior  If the 600 cluster will allow you to choose that in the display.

C 1 has been the best clutch set up for me. I do have 23g sliders , but that is because I went up in tire size.

Lost some top end... max mid to upper 40's but it runs the trails great.

I run with a lot of friends with bigger machines but the little 600 holds its own.

I live in Pueblo, shoot me a PM if I can help you with anything....
