bongobobny Posted April 21, 2009 #26 Posted April 21, 2009 Sonny, my big "Barn Door" Clearview screen robs me of about 3 - 3 mpg highway speed. I generally get in the mid 30's for MPG whatever that is in kilometers/liter...
Roy Hoffman Posted April 22, 2009 #27 Posted April 22, 2009 I constantly get between 45 and 50 mpg running at 60-65. At 80 it drops to around 40. I have a mid size windshield from Yammy. I usually add some seafoam every couple hundred miles or so and I run synthetic oils. I sink my carbs around 2-3 thousand miles, it's simple now got lot of practice, doesn't take long. I also have KN air filters but I don't know if that helps or not. Roy

Stoutman Posted April 22, 2009 #29 Posted April 22, 2009 My 05 RSTD windshield seldom comes off. The worst gas mileage I ever experienced was coming home from Utah. I hit a headwind around Amirillo Texas. I was driving 75 mph into a 25 - 30 mph headwind. It got a little dicey as I had to switch to reserve about 5 miles from Amirillo. My calculated mpg that trip was 33 mpg. Now when I hit a headwind I either slow down or stop for gas. Normal city riding yeilds about 37 mpg, and highway is normally 41mpg. When I take a group ride with a mixed bunch of scooters and harleys I can get upwards of 50 mpg, only because everybody seems to go so slow.
CrazyHorse Posted May 4, 2009 #30 Posted May 4, 2009 On my RSV I rarely get above 35 to 37 MPG and a lot of times I'm in the 32 MPG range and that is with a speedohealer corrected odometer. I ride with Gold Wings and Harleys and they all get much better mileage. I typically use at least 1/2 gallon more at fillups, with or without wind. If you are running a RSTD or RSV without a corrected odometer/speedometer you should keep in mind that you are actually getting 7% to 8% less mpg than you think. DT PS. Last summer riding across Kansas in the wind I got down to about 22 mpg and it was brutal. I think if we had fuel injection on these bikes we would have different mpg's for the better. Riding with friends 1 with GW, 1 with BMWK1200 LT and me I'm getting in 30's mpg the GW getting bout 42 mpg's (1800 CC's) BMW 45 mpg's. They both get irritated with my bike where they can go so much further w/out stopping. Goldwings have had fuel injection since 1985. 24 years later Yamaha still cant have fuel injection? Come on. I myself are getting tired of carbs now I'm getting in the 20-30 mpg range something with the carbs or I'll have to check the coils/spark etc.
SilvrT Posted May 4, 2009 #31 Posted May 4, 2009 I've been getting around 27mpg this year out of my Venture. Most of my 17 mile commute to work is open highway where I run 80mph, and this is a speedohealed true 80mph. I'm sure this info is in here somewhere but thought I'd just ask anyway... Is there a chart showing the speedo readings @ each 10 mile or kilometer setting and what it should be with the speedo healer ...?? and where can a guy get this speedoheal
RSTDdog Posted September 3, 2012 #32 Posted September 3, 2012 Goldwings have had fuel injection since 1985. Actually only the 1985 and 1986 GL1200LTD had fuel injection- PGM FI a version of early fuel injection found on Honda cars that had a crapload of vacuum lines associated with it. Not many of these bikes were produced, they ran great when they worked, the FI was problematic and expensive to fix when it didn't. All the 1500 Goldwings are carbureted (they only have two carbs, one for each bank). That tells you what Honda thought of their attempt to FI the GL1200. The GL1800 is the first wing with fuel injection. The Royal Stars get what they get for fuel economy mostly because its a 30 year old engine design and the bikes are heavy. Just Adding fuel injection to this engine design would improve driveability but likely wouldn't improve fuel economy much if it all. RSTDdog
hunter 1500 Posted September 3, 2012 #33 Posted September 3, 2012 I get 41 to 43 if I run about 60 mph depends on whether I'm in the mountains or valley. Towing the trailer now that I tuned the carbs I get about 35 to 37. Lower number would be on the slab and higher number on secondary roads. Before I was getting less than that. Oh by the way I have a aftermarket fairing on mine.
TDunc Posted September 3, 2012 #34 Posted September 3, 2012 Wow, terrible mileage.. When I had my 06 RSTD, I always got great gas mileage. Now, If I was running ummmmm.... 80ish, most of the time, it would be lower but I always received on the average 175 miles to the tank. No lower than 38 miles to the gallon.
Dave77459 Posted September 3, 2012 #36 Posted September 3, 2012 Some threads just never die! Ain't that the truth! 3 years later, Roxie has 70k miles on her and gets the same mpg. 140 miles and I'd be desperate. Now I've added an aux tank and hot 275 miles comfortably between gas stops. Dave
RSTDdog Posted September 4, 2012 #37 Posted September 4, 2012 Some threads just never die! Researching windshields (windscreens) ran across this thread and just couldn't let the inaccurate Goldwing FI reference go uncorrected. Not to mention poor SilverT has been waiting 3 years 4 months for info and a link to his speedohealer question ( although what do you expect when your hijacking a thread ). I missed that question being it was the last post before mine and I was overcome by the GOldwing FI reference. Just not right having threads around with unanswered questions in them...... So here you go SilverT. http://www.healtech-electronics.com/ Perhaps now this thread has closure....... RSTDdog
Sonnysboy Posted September 4, 2012 #38 Posted September 4, 2012 Had a 2009 RSV and my fuel mileage was always around 35-40 mpg. Most of that two up. Never pulled a trailer so I can't speak of that condition. But I have a 2006 RSTD now and when I rode it to Va. from Pittsburgh, 2 hours on the turnpike, 4 hours of back roads, I averaged 45 mpg all the way down. Since then I've put close to 2000m in the last two months, riding double, on it and I am getting between 38 and 42 mpg. Pretty happy with that, considering most of my riding is back roads and the RPM's you need to run at to keep these V-4's happy. Regardless of the tank mileage, I always stop at around 130 to 150 miles just to take a break and a drink. Very rarely have I ridden a motorcycle to get from point A to point B as fast as possible. I enjoy the ride and my wife enjoys the view, makes for a great day on a bike. I've also found that most of the guys I know compute their fuel mileage, like my dad did, rounding up to the nearest number that was better then mine. I found that, on the occasions when I ride with others, I'd look at how much gas they put in at the stops. Amazing how the MPG would drop when you do that.
Venturous Randy Posted September 4, 2012 #39 Posted September 4, 2012 Too much lugging will definitely effect gas mileage. If you are pulling hard enough that to accelerate easily and have to drop a gear, you probably should have been in that gear anyway. As I have said before, if you drop a gear and the bike speeds up and you have to let off to maintain the same speed, that would be the best gear to be in. RandyA
dacheedah Posted September 4, 2012 #40 Posted September 4, 2012 I would check to see that you are firing on all cylinders, check the temp when running and see if one is cold or just warm. . .
