Just wondering what fuel mileage guys are getting? I've got 1400miles on and checked every tank ridden all conditions and I'm only getting 11.8-12.8 MPG. I'd get 14-14.5 with the nytro and apex. I'm thinking I need a throttle body sync

I have almost 2000 miles on her now and I love it! After a little tuning on the fuel controller and some fine tuning on the clutches it runs awesome! It's quiet and mpg are pretty good. MPI builds a really nice turbo and Matt is very helpful. I'm really happy that I got the turbo it makes it a really fun sled! Zero problems with the turbo and the sled. So far so good!

I've only managed to go from fuel light to fill up twice. We usually get gas any chance we get. The first time was the first tank through the machine during break-in, which was 11. The second time was 14. I assume its going to keep getting better as I only have 400 miles on?

My 09'nytro would get 15 mpg plus.... Would be surprised if they came in less than that!

I got 160 kms when the gas light came on. I was loaded with gear, spent lots of time WOT and in the powder and I have the 1.75" track. Still not great mileage (less than 13mpg?). Anyone know how much gas is left in the tank when the light comes on? Anyone run it bone dry to find out?

I was on the first TY ride and we went from Hancock to Greenland 83 miles and I ran out 2 miles from Pats Yamaha. I only got the low fuel light when I was playing in a pen about 3 miles before I ran out. It has come up since then but only getting about 11 mpg. My fuel is set up fat but I like the AFR #'s so I will deal with the mileage issue.

Any issues restarting after you ran out? I was alone about 50 kms from town when the light came on and wouldn't push it. I should also note that it's an XTX with high windshield and when I say loaded with gear, I'm talking 50 pounds additional to my hefty 250 with riding gear.
Yes - it only ran on 2 cylinders up to 6000 rpms. I am not sure this was an issue from running out. I thought it was a vapor lock but now think I have an electrical issue. I think it may be a result of pulling the hood so many times or a loose wire from the turbo install.
