GP1300 2006 fuel economy compared to a 2004
Over the weekend I went for a blast with a friend on a stock 2006 GP1300r with 8 hours on it and it seam to drink juice compared to my modified 2004 GP1300r. Now I have VF3 reeds, EFI, Race flame arrester, D Plate, Jetworks, “05 pump, 14/20 DF, 155 heads, keyway mod, grate & one of Jims plates. After 20 miles of hard riding I was on ¾ and the stock 2006 was had been on half for 8 or so miles. I checked on the level of fuel in the tank and the 2006 was about 1.5 inches down on mine, so it was not a simple as the difference in the fuel gauge. For the next 20 miles I rode hard whilst the guy on the 2006 1300 went into economy mode. After 40 miles he was on the buzzer & I was fluctuating between ½ and ¼ tank, I had another 5 miles before going to ¼ tank and another 15 before the buzzer.
With all the stuff on my ski I would have expected mine to drink fuel quicker. Is this something any of you guys have noticed about the 2005/2006 non PV 1300s?
Also, in the 3 to 4 chop his ski would cut through the chop whilst I was bucking away. The stock ride plate is going back on as I couldn’t keep up with him as the pump would not keep loaded..

You have just seen first hand the misconception about these boats. Everyone has always thought that these boats will drink more gas (being modified). Well that is true in lots of circumstances but for some other cases --- the higher compression heads are actually exploding the fuel more efficiently in the chamber (it actually just burns ALL of the fuel in the chamber without any left over).
So in this case - it may very well be that your mods are yeilding you better fuel comsumption than the stocker boats pushing 120-125 PSI in the heads.
I have said this before and people have disagreed big time on this - but you just saw what i am talking about first hand.

I really think it comes to the carbs with our boats and drinking a lot of fuel. Stock carbs or even slightly modified carbs seem to yeild better fuel economy then the EFI boats. It's when you go putting the big carbs on the motor that she starts to drink more. Eventually, if the 2-stroke was staying around...I think the EFI boats would come up to pare.

my modded gp1300r will out last my stock GP1200 every time but that maybe due to the hull difference
I figured it to be from the fact you didn't have to beat it as hard to go were you wanted to go

Most of it, is that lever on the right side of the handlebar.
Granted the GP12 drank tons more gas than the GP12R or 13r. Nothing was as miserly as the Polaris domestic engine... Most four strokes can't achieve the results of that line of engines.

So umm which mods would help with yielding better fuel consumption? I am sure that hull + pump mods might help, but which engine + carb mods? Just wondering cuz, on the river the beeper goes off on me in way less than 2hrs.

Remember also that when the buzzer goes off - you have 3.5 to almost 4 gallons of fuel left in the tank on avg.

Yea I know, but thats only an extra 15 mins worth of riding. Is there any way to make the buzzer go off later?

My 05 is highly modified.
A bunch of us rode 30 miles up the St Johns 2 weeks ago and 30 miles back.
I used 14 gallons of gas which = 4.286 miles per gallon. It uses a lot more fuel now than when it was stock. Total range now is 68 miles.
