Yeah I had temp issues early on with my 800. Although I didn't go through the entire process of draining and adding a specialized coolant I did add water wetter. I did notice it helped sparingly. Eventually what solved my issue was a new larger billet completely welded aftermarket radiator. Another thing idk if I added previously was a ton of CA guys do tunes to lower temps right from the jump. As these machines aren't tuned for efficiency from the factory they are tuned for compliance!!
