I know you really should not care about it since thes are toys but wow. I have a 650I and it makes my full sized truck look like a gas sipper. I have gone through 5 and 1/2 tanks in 117 miles.

 

somethings wrong. do you idle alot? should be 2 tanks tops

 

No not much idle. I have 19 hours on it. It is at exactly 122 Miles.

 

It does not smoke and of course I just got it back from the 10 hour service. They did not mention anything even after I said It had really bad fuel thirst before it went in.

 

I have seen a post of a 08 750 that had the fuel line hose come off, yours could be loose & leaking?

I have 4 hours on my 08 650i @ 28.8 miles used maybe 2.5 gallons. still in heavy break in mode. (1/2 throttle)

 

And then there's this

 

Go to any Auto Parts Store or Walmart and get a can of Sea Foam to treat your fuel , you can also get Deep Creep to spray directly into the carb ; and you can treat your engine crankcase oil with Sea Foam to clean out the sludge from the engine !

The Sea Foam will clean the engine from the engine inside out all the way to the combustion chamber , i have used this product in my fuel and it will keep the emtire fuel system clean ; and also clean's the combustion chamber of builtup carbon deposit's !

I highly reccomend Sea Foam and Deep Creep for gasoline and deisel fuel powered 2 and 4 stroke engine's , it comes with a money back Guarranttee and has been on the market since 1942 ; any product that has been on the market that long and still carries a money back Guarranttee has to be a good product !.......

 

Umm, not insulting your intelligence at all, but you may not be completely filling the tank. Brutes come with an insert in the fill pipe that will restrict how fast fuel can on into the tank drastically. It will be a full 1-1.5gallons from being full and gas will come up to the top leading you to believe your full, which ridden under normal some fast, some slow riding will leave you refilling again at around 40-45 miles. Just a thought. Good day.

 

I second the motion on SeaFoam. I use it in my boat, truck, ATV, lawnmower, snow blower etc., etc.. It's called "tune-up in a can" and sometimes it seems like it is. When I picked up my first ATV ( a 2003 Prairie 650) it was running rough tight from the dealer. The dealer grumbled about the crap gas they had in that town and poured in about a 1/4 can of SeaFoam. The engine straightened right out. Not sure what kind of solvent is in it, but it works.

 

During fill-ups, pull out the white Tube in the Gas Tank neck, fill ONLY to the bottom of the filler neck, reinstall the white tube, this is what "Kernel" is refering to.
On my BF750 I am avg. 85 miles to a tank & I did that too on the '07 & '05 BF750's I had before.
