The wife and I couldn't take it any longer. We had to get ourselves a couple 2016 Timbersled ST's for our Yamaha YZ450F's!! In late December we ordered our kits from our local dealer and within a few days I had them put together and ready to ride! Thanks to a ton of great info from this forum I was able to make our bikes snow ready before we ever left the garage. ThermoBob thermostats, Moto365 engine covers, Flo Foam pre-filters (made specifically to fit in newer FI YZ450F's shroud intake tracts), Pod filters, Mt. Addictions gas can, and we have had a winter to remember!! No major issues like fuel or water in our oil. Bikes start and run great! We are officially forever hooked on snowbiking! The bike with the white plastic is my wifes 2013 YZ450F and the blue plastic is my 2014.
