After buying our 2017 f3t, i questioned if it was that much better than our two up riding on our 2015 f3s! The wife and i were still bottoming out on select NJ roads. I decided to go to the nearest air pump and check out what our air bag had in it for air. Guess what, no air. Filled it to 55# and put some soapy water on the valve stem to see if i had a faulty core. No leak from the stem, but where the stem is screwed in was bowing bubbles all over the place. BRP puts locktite on the valve stem, but it wasn't tightened all the way. Had a "bitch" of a time breaking the locktite seal, but was finally able to break if free and get a good seal. Have contacted my dealer to order ndw parts and replace. What a difference the ride is, "with air in the bag!!!!!!!"
