Was out for my first sled ride yesterday up Meadow Mountain where the majority of the riding is between 7000-7700' and could not get my sled to pull over 7800-7900 on any pull. There was about 2' of powder and about -5 air temp so pretty light stuff. Sled ran awsome in the mid-range, never a bog, and throttle response was bang on. WOT however would stop at 7800 with the odd blip to 7900. No codes have been flashed either.
Last season, my sled was completely stock and would pull 8150-8300 on any pull, though most local areas are closer to 6000'. Over the summer, I swapped out the 155 for a 163 track, put on an HPS can, SLP blue-pink with metal glide washers, delron on secondary, fuel filter, drained and filled with fresh fuel (91 Shell non-ethonol only), new plugs, and cleaned exhaust valves. I was thinking that my RPM's would have increased with the new spring and the can but I'm going the other way. Weights are the stock 10-62's as well.
So, where should a start? I can take it to the dealer but then it's going to be 2-3 weeks as they are really backed up this time of year. I just want to go through everything I can before taking it in. Could this be a TPS or other electrical/computer type thing? Almost seems like some type of limiter is kicking in at 7800.
