Just fyi, not much of a forum or social media regular, but to give credit where credit is due, I built and ran a 2016 300XC converted with the BRC 500 conversion and a 2020 Yeti this year. Added a Hygge custom pipe and It's a paradigm shift. It makes 80HP, and is reliable tried and true. There were a few problems/adjustments to make it run right, but Riley and BRC Racing was responsive (shout out to Kelley) gave me amazing customer support and this thing pulls like a freight train. It gathers speed through the deep like no other bike I've ridden. They've been building these for the dirt for years, omg, but it really shines on a snowbike when you're WOT all day.. The best feature is that BRC runs these engines in their Carts at 120HP. There's still room to grow, even more potential. Awesome engine, great company, they have the passion to build the best product, not just meet a pricepoint or market.. They're working on EFI and a CVT also... ! 2 strokes forever! Glad they didn't sell out to Timbersled. God bless Canada.
