I wonder how the Moriwaki low mount map would work with Banzais...
Try it then you will know. I tryied the DK map for the low mount Sato's and my mileage dropped to 29 mpg. The exits of the pipes were sooty black and there was black sooty spots on the license plate from the exhaust.
Seemed a little rich to me.

Same for me. I was only surprised at the MPG after reading what everyone else said they were getting out of their RC51's. On a note my custom map has mostly minus figures in it hence it is running leaner than standard. That added with it being setup properly which means a more responsive throttle which means less throttle required to get the same results = great MPG!!
Wonder what it is that makes the Sato's need so much fuel?
I did run one tank full with the Dan Kyle map and only got about 100miles out of it. Should be over 130miles with the map I have on there at the moment easily.
This thread really has me thinking about the DK map with Sato Banzai pipes. The milage I get is the shits, even at even highway speeds. The pipes are pretty sooty and it runs worse at altitude. I'm wondering about a rich condition. Dyno time is beyond the budget at the moment, but I think I'm going to have to make this a spring project.
Realize that the Kyle maps, Dynojet maps, etc, are made at different areas of the country and atmospheric conditions, the latter being the key. Additionally, it would probally not be wise to produce a map that was cutting edge because you could end up in a lean condition, and that would not bode well for the map producer. Its a good solid ballpark map. Its up to us to fine tune to our conditions, and thats where a good dyno session comes in. If the dyno facility does not have an air/fuel measurement device with their dyno, then just how good of results could one obtain? So keep that in mind. I can't give you fuel mileage as my RC is track only. However, after 6-7 20 minute sessions at a track day, I'll go thru 10 gallons of gas. Its mostly wfo ya know....lol.
Mine was done maybe 50foot above sea level. My Dyno place is right on the water front here in the UK.
Must just be the different pipes, or maybe a richer map works better on the track? Each bike is different though and is only made to factory tolerances. If they were all blue printed it would be so much better as at least we would all know where we stand engine wise.
Mike, I need to get my RC on the friggin dyno to clear a few things up. One of those is they have much stronger torque than the Yosh pipe in the mid range ( I want that proven rather than seat "O" pants ) and that has the price of milage. I'm now down from 94-100 to 70-80 mpg .
Dan Kyle is located at sea level, so if you're higher in elevation that may be part of the problem as mentioned above.
I'm only a couple of hours away from Dan. Sacramento is at about 80 feet or so above sea level. Something just doesn't add up when some folks are returning 40+mpg and others are under 30mpg. Granted, my figure is corrected through Jim A (can't remember his last name) speedometer doohickey and with my size/height carrying more weight and it's out in the breeze, but still... Freeway miles for me net about 30 mpg at reasonable ticket free speeds. If I'm screwing off in the canyons, I'll drop to around 23-24mpg. Keep in mind, I rarely get the throttle WFO. I typically ride 'The Pace'.
I'll give Dan a call and see if he has any suggestions. I'm thinking a dyno run is in order anyway. Even if the map is fine, I'd like to know some details just for shits and giggles. Who knows, I might need a baseline run for future mods. That damn Thorsten tries hard to get my money...

Something to keep in mind when computing fuel mileage when a speedo healer device is fitted is that the odometer reading is off by the correction factor entered in the speedo healer. The stock odometer is pretty darn accurate as far as recorded distance traveled as long as no speedo healer is fitted. For example, I have entered a correction factor of 8.5 percent in my Ahlman for my stock geared RC51. I tested my theory with a GPS unit. One hundred miles recorded on the odometer compares to just about 108 miles on the GPS unit. Of course the guys with gears may have around 13-15 percent correction factors.
By the way, I feel my correction factor is fairly accurate as far as speed, the GPS unit recorded 154.9 mph as the bike's speedo just ticked 156.
Does anyone know what Dan sets his fuel/ air ratio at when setting a bike up on the dyno? Maybe this has something to do with it too?
I'm sure mine was set to run at 13 as per the OP on this thread. I will check when I get home on my other printout I have which compares that Sato map with my custom one.
My bike has totally stock gearing, stock sized tyres and no speedo healer fitted. That's kind of odd how the speedo reads over but the odometer doesn't, but useful to know.
Eye-p it took my dyno place 3-4hours to make my custom map. Not sure how long it would take this guy but at those hours would be tight getting 5-6 done in a day. Unless you are just planning to run them up and see how they are fuelling without any adjustments?
If you guys get a group together here in No Va, let me know how many its looking like, I'll base it on 5 for now. I'll call John and see what kind of a group price I can arrange for you all. Also, I'll see if there is a central place he can tow the rig to for all to meet to do this. I will have my torque results shortly from the session.

The correction factor still would'nt account for the dramatic mileage difference with the different maps. When I did my mileage test they were all done with the speedohealer installed so the correction factor was the same for all.

I agree with you, but I wanted to suggest that some people's mileage may be slightly better than what they thought. With a 10 percent factor, mileage computed at 35 mpg becomes 38.5 and not quite as bad. I noticed a drop in my mileage when I fitted my Arata exhaust and loaded the Dan Kyle Arata map which is not greatly dissimilar to the DK Sato low map when compared over the full rev range. Examination of various maps for the different exhausts does indicate that the DK maps are noticeably fatter in the 3500-5500 cruise range on light 10-20 percent throttle openings which would impact fuel mileage significantly just cruising down the road. In this same rev range throttle openings of 30-100 percent the maps are much fatter also, so that hustling down the road working the throttle is going to burn lots more fuel.
It also seems to me that the European bikes were mapped richer as delivered from the factory as compared to our American spec bikes because most of the dynojet maps for the Euro bikes both standard and aftermarket exhaust are really leaned out from the factory settings except of course in the 2-3000 rpm stumble range. This is just speculation on my part, but it might explain why people have poor results when loading Euro maps in our Ameri spec bikes.
I would love to get a look at Mike0251's map with the Powercommander software, also PaulSP2's.
Dan Kyle is located at sea level, so if you're higher in elevation that may be part of the problem as mentioned above.
+1.......what ppl need to understand too is that all our bikes are different to a degree that will affect the mapping one way or another. Many yrs ago when I didnt know any better, I too, thought grabbing maps from others was all I needed.....wrong. You want a good map? Spend $150-200 for some time on a decent dyno/tuner and you'll have YOUR map.
