Hello to everybody that ils still active on this forum. I just picked up a 2021 Kawasaki Brute Force 300 for my GF and I'm riding a 2021 KQ 400 myself. Here's a service manual for the 300, I hope it helps someone who's stuck working on one. I believe these are made in Korea by Kymco, also marketed as an MXU 270 and a Tracker 300 at Bass Pro Shops here in the US. I'm not sure how similar the machines are but I would hazard a guess that a lot of the powertrain parts/info are interchangeable. I can only post a link to my Google Drive but if you tell me that you're from BF I'll grant you access.
