Big drop in gas mileage

My bike came back from the recall the other week. I am driving it for the first time on the highway at 70mph. The bike would get 47mpg at this speed in 6th.

Now I am getting 37mpg. The only drag on the bike are hippohands. Any ideas what is going on?

Head winds?

if you're running the Hippo hands without handguards, then the wind force against them could be pushing on the front brake lever enough to activate the brake somewhat. This is a known issue with some bar mitts.

High airspeed (Bike speed + headwind speed) and cold temperatures affect mileage.

I picked up my DL1000 from my dealer Thursday eve. I only had a 20 km/12 mile ride home.. temperature was 9f or 10f (around -12c) Couldn't really base my mileage on that short run in those cold temperatures.

Rode to work this morning. it was +4c or about 39f. Headwind of about 20 mpg. I went a bit faster than normal on the highway (130 to 140 kph or 80 to 90 mph) and I got poor mileage. No surprise there!

My tire pressures are fine.. they are over-inflated a bit since I was expecting to ride in colder temps.


I'll have to check over the next few days when I (hopefully!) get into more normal riding.

..Tom

My Opinion:
Vee or V= DL1000 before 2014
Vee2 or V2 = DL1000 2015 to 2019
Vee3 or V3 = DL1050 2020 to?

My Stroms:
2006 DL650: 202,000 km 125,500 miles, Sold
2012 DL650 139,500+ km, 86,700+ miles. Sold
2015 DL1000 New July 2015 205,000+ km, 127,000+ miles.

This can help preventing from cars pulling out in front of you (SMIDSY)

yep, fuel air ratio, denser air requires more fuel, one of reasons I always say cold air = free horsepower

but I guess not free if you consider the additional fuel consumption

there are other reasons that fuel economy drops in cold weather as well, but that is the big one

I think also the lack of an intake pre-heater means that the fuel doesn't vapourize as well and as a result the injection has to run richer than it would I warmer weather.

Check your tire pressure.
