Mines running 50:1 now after the turbo. No problems that I'm aware of after about 350 miles. I might start putting a few ounces in the tank though too. Not sure that it's necessary but a cheap safety net.
I ride a 08 PG D8...on on xmas eve I rode with a brand new 2011 Pro-RMK 163". There was about 4 foot of fresh to battle. At the end of the day I was on reserve (on the gas cap) and he was just getting down to half a tank. I never really thought about fuel consumption until then. Either my turbo @9 lbs is very thirsty as well or those new pro's are like a camel...one drink every 2 weeks. Ya get what I'm sayin man
Yesterday, PRO RMK 7.5 miles per CDN gallon which is about 6.6 miles per American gallon. Breaking trail all day and running 50-65 MPH most of the time. I thought this is similar or worse then my D8. Overall consumption of the D8 was extremely low though, it was in the shop all winter.
A lot of it depends on riding style too. No matter what sled I ride I'm always the first one out of gas. It's been that way for as long as I have been riding out west. The turbos def. burn a lot more though.
