2018 Axys running rich?

[hondalrd]

Hey everyone. I have a 2018 Axys and it has always seemed to run rich. It leaves a good brown stain on snow when I punch the gas and stains my exhaust side panel. I have owned other years of Axys and never had one run this rich. Any body know how to adjust this or what would be causing it? Has about 53 hours on it

Yep I had 2 of the 18’s and both were really rich. TPS was biggest headache and made them run fat. One sled required TPS replacement other sled was able to set. Just ran rich all the time.

Can you set those at home or is something the dealer has to with being the plugged in?

I recall trying to adjust my TPS on my 2016 Axys 800 RMK. I think it involved putting a long screw driver from behind the tank to reach the adjustment on the throttle bodies. Pretty sure I got the instructions from Snowest forum.

Can be done. Just need a digital voltmeter and patience.

My '13 started doing this as well, after I turned the oil pump up.
