Yup Stack, I'm in the same boat. Came off a M-series and now have an '18 Snow Check 162.
I'm 48, very experienced, aggressive rider and I'm not comfortable yet on this sled as well. I too have a 5.5" riser delivering today. Shock set up is crucial and with the low snow conditions we've experienced here in Colorado and southern Wyo, I just haven't felt comfortable pushing the sled yet.
Great advise above. I too will stand tighter in the "stirrups" and get out and tear some donuts!
Sled is awesome. I know it's just me that is the problem.
Q
Figured I should update,
I went out last weekend with the updated pressures mentioned above. Primarily less pressure in the front an rear shock, running #2 on the trail and #1 in the bush. I rode most in deep touched logging roads and a few easy climbs, but the point was to get more comfort with the sled. I will say that has had a lot of smiles! Changed my riding position and have challenged myself to not do those things like I did on my old "M" that lead to the diving. Its coming together, and this things is really fun with sidehilling too....practicing that as well. I still to had contend with a bit of the diving, but its kinda specific to situations, and mostly at slow speed for me. Once I get a bit more comfortable I'll get into the tight tree climbing that we have up here. My Front Shock on the rear skid is the standard coil over, so my setup is unique as my other shocks are the Mountain Cat QS3's. I might update that to the QS3 or look at adjusting the spring to see how it reacts. Note; I also added the 5.5 riser which was a but more comfortable to me, only added an inch from the stock 4.5, but I feel a lot better on the sled.
Thanks for everyone's feedback so far, it has been very helpful, and gave me motivation to keep moving forward on this awesome sled!
