I hear ya, love the performance but it does come at a cost. I have been tempted to lean out the AFR but I can always find fuel within 100 miles.My first real trail ride this year with turbo, ear to ear grinbut at 11.5mpg

I have 21 41 xtx gears that i will be replacing my 24 50 with, that should help a bit for now, once i get some gauges for it I'll try to lean out the cruising speed 40-75, I'm pretty sure my gems settings are a bit on the rich side any how, as someone is looking out for me so i don't melt the motor until i do get gauges, thanks Mr Sled.I hear ya, love the performance but it does come at a cost.

I'm consistently around 13MPG. It's only a 10 gal tank and my buddies all ride polaris with 12 gal tank so I'm the one usually concerned about the next fuel stop only because they can carry more. I'm also a lead foot on throttle (just like everyone else I'm sure)

Always better than 13.5 mpg but I've seen it run up to 16.5 if I drive like my grandpa.

How is everyone getting their numbers? Is there a setting on your gauge that you can set to keep track of your MPG or just doing the math ? Thanks

I also burp my tank, by putting my knee on the back bumper and compressing the skid, you can get another 3/4 gallon in.
