My 2011 was horrible on gas with stock 14 gr rollers. Looks like for the 2018+ 450 they upped the rollers to 16 gr, and you have EFI, so I'm surprised yours is hard on gas. I run 18 gr overdrive sliders in mine and once I take my primary apart this winter I think I will be switching to 20 gr rollers. You could try 18 or 20 in yours to see if that helps your mileage. What kind of terrain do you primarily ride, and at what typical speeds?I have <50 miles on mine (2018 450 w/EFI but no EPS)- it does seams to consume a lot of fuel
Would be interested what others are getting
2018+ = 2018 & 2019 (currently) Grizzly/Kodiak 450 model yearsSorry if I am missing something here - not sure what this means " 2018+ 450 they upped the rollers to 16 gr," what is a gr? Gear Ratio? If so it's completely stock.
It's driven 95% of the time on our property a mile or two up and down to the lower 40ty - slow to moderate speeds up and down hills - we are old retired folks no need for speed
The gas mileage does indeed "suck" as compared the older 1999 Honda TRX300 - The Yamaha is EFI the Honda an old school Carb
