My family is thinking about going out west to the Big Horns during Spring Break. I have two Nytro FX RTXs and I would need to change the clutch weights and springs but I'm not sure what to get. Anybody point me in the right direction?
I realize they are both short tracks but if we spend our time on south facing slopes the snow should be set up and riding should be OK. The trails would be nice and there could be some powder riding if it snows. I would rent but my son is not old enough and he wants to ride too. Understandable.

If you you are running the stock tracks, then you should be able to just change the rivits in the weights and gear down as per the Yamaha clutching/gearing chart for the elevation your going to be riding at.
Rivits and a 20 tooth top sprocket are fairly low cost.
If you have a taller track then you may want to use the same total amount of rivit mass per weight, but instead of putting the heavier rivits in the tip as the clutching chart shows. Put the lighter rivits in the tip and heavier ones in the heel.
The clutching chart is usually a good starting point. It's fairly common to have to fine tune from the chart though since each riding area/sled is a little different.
Once your in the mountains and riding, I like to write down what my rpms were at lower and higher speeds. Then if the rpms are off a little, you'll know what change to make for the next trip to the mountains
