Hello,
I am new to grooming and utility sleds.
I have purchased a left over 2010 VK Pro. I had the dealer install the sub-rad kit and scratchers on the unit prior to pick up.
I did this based on all the information I could find on this and other sites as well as as many grooming related sites I could find about 4 strokes and pulling.
I am not subsidized by my local ski club and I also wanted to do a bit of touring with it, so I don't want overheating issues reducing engine life.
My first experiance was 3 hours packing in 18" deep fresh snow. (2 mile loop)
3 hours later I pulled the drag (home built 300lbs) around for another 2 hours at about 10 mph.
I did not have the scratchers down and did not turn on the manually operated fan on the sub rad. No temp light and the temp outside was about -15C (-5 F).
pretty happy with the power but not much experiance to compare to.
If anyone else has the set up, I would appreciate talking to you to learn more.
Thanks.
Wayne in Sask. Canada.
