+1(Samurai-Jim @ May 11 2007,07:52) I get a huge variation in range depending on how I ride and where I ride.
Even going easy around town stuff I will get about 140 miles just like your saying.
Cruising at 70 on the highway with very light throttle across the desert I got 230 miles and still didn't see the light come on.
Normal higway riding with occasional high speed blasts I will get 180ish and see the light.
Horsing around town blasting from light to light, maybe a burnout or 2 and I get 120...
Its all over the map.
+1 here too, I was suprised how much it varied from around town riding to highway riding.(Samurai-Jim @ May 11 2007,06:52) I get a huge variation in range depending on how I ride and where I ride.

I went thru a similar thing on mine. I looked hard at my driving habits and those hadn't changed that I could think of. In my case I had my throttle bodies synced and while the bike ran way better as far as idle smoothness etc, my mileage dropped wayyyy off. And you could smell raw fuel on acceleration and after decel. In my case it all got solved when I recycled the ECU. The theory to it was concluded to be something like this. The ECU had the old TPS position in its memory set from the factory. When you sync the t/bs you actually chnane the butterfly position and that thereby causes the TPS to be in a different position yet the ECU still thinks its at the old position and sees the new position as a new demand for air fuel management and added fuel. When I reset the ECU my mileage returned to its original nice numbers. I since added a PC3 running a stock map and my mileage got even better. Here is what I find. If I drive easy on the throttle say 20-30% throttle and shift below 3K I can maintain 40+ around town and about 50 on the highway at about 70-75. As soon as I get past that and the more agressively I do so, the mileage goes markedly and quickly down. Don't get me wrong I can run her up to the limits and do so, but I also know that as soon as I do, my mileage will go south quickly. So I also have learned to discilpline my driviong habits even more acutely since gong through this experience.(KanjiBusa @ May 11 2007,04:40) So I fill up my tank, and a few miles later (140mi) the low fuel light comes on....I did not ride it hard this past tank. Why is the economy so low?
Service interval for plugs is 15K miles. Your busa will run much better with some new plugs.(BUSADOOK @ May 11 2007,08:41) Damn you guys, i've been getting 34MPG. and i drive like an old man. Maybe my plugs are bad? i have 31K miles on mine, and i don't know if they've been changed.
