I thought I would take the time to post some riding results on my wife's 2013 ProRMK 600. Over the summer I installed a Carl's Cycle 660 kit with clutching, a Kmod rear suspension conversion with fox floats, a C3 syncrodrive belt drive upgrade, and finally, Evol R's in the front suspension.
1 - Carl's Cycle 660 pulls very hard, comparable to our stock 2013 M800, but revs quicker and is an absolute blast to ride. Carl's clutching and mapping is spot on, doesn't appear to use much more fuel, either. This is a great mod to any 600, and it is so fun to ride, you won't be missing the 800 IMHO. Jackie came off a modded 09 M8, and she stated this package is by far superior.
2 - Kmod rear suspension upgrade: We used fox floats on this sled, and absolutely have no complaints. Ride quality is second to none, transfers weight effectively, works great on the trail, climbing, or in power. Great product.
3 - C3 belt drive. It's nice to have gearing options available (we kept stock ratio with the 660 kit). Well thought out, adjusted belt tension after break in. Runs cooler then the original Quick Drive...
4 - Evol R's: Had to remove sway bar to fit onto sled, so increased pressure to compensate. Running 54 psi / 160 psi, rebound set @ 9 clicks out. Big improvement over the stock Walker Evans shocks, even with a Zbroz spring upgrade...
All in all very happy with the improvements - this may be the most perfect sled we've owned to date - light, handles great, and tons of fun.
