I went out and rode mountain passes and canyons with a buddy in Denver maybe 3 years ago and was astonished with the gas mileage I got out there at altitude.

I would bet that my FJR would see 50 MPG if it was all hiway and cruise on. For me the fun factor over rides gas milage. Brian and I were in some curvy roads that I never went out of 2nd gear and was speed up and slow down almost at the same time so it was krappy gas milage and a little oil out of the air box hose. Saw a little oil on the ground after parking for the nite and it had come out of one of the drain hoses under the bike but that has been the only time. I have cornerphobia but the FJR did not have me scared.

You could absolutely get 50+. The conservative Goldwing rider I mentioned above is my oldest friend, and when riding with him I get 50+ reliably. I took a recent 3000-mile trip alone though, and I averaged in the low 40s. In South Dakota I was getting high 30s, and that was on the highway with cruise set ....... on 92.

Just keepin' up with traffic, Officer.

Yeah that's a malfunctioning gauge. My 600cc YZF doesn't have one, so I use the trip-meter. How many miles I get after the light comes on, has varied widely. It's primarily dependent upon the mileage, rather than gauge. I've calculated mid-high 20s, high as low 50s. So it's easy to see how it would run dry with a 20 mile variance. Add to that, it seems to need a refill sooner, in the unusual event that it's allowed to sit for a couple of weeks or more.

I can see low-siding on a turn with a quick increase, but decrease? Either low-skill, ran out of luck (critter/debris) or both. One probably followed the other, right off the proverbial cliff.

Nice S curve... 34 in a 55 and he still couldn't (or wouldn't) keep it on his/our side of the road. Imagine if you were busting it, taking that S curve coming from the opposite direction.

Just plain drunk or impaired. But taking blind curves in the wrong lane is precisely why I stay the heyell away from "enthusiast" roads. Countless YouRube videos of that crap. With very few exceptions, what hits YouLude, doesn't include the blind-curve wrecks.

Sounds like the oil was overfilled. Even with sustained high RPM while leaned over, the engine shouldn't be sucking up oil. Don't know about the FJR, but the YZF is supposedly to be measured, level on a bike stand, (not on the kickstand), and with the dipstick just set in the hole (not threaded in), with a warmed engine (parts/oil expand to make the level read higher). It's also possible to just, over-oil the air filter... assuming it's the oil type.

The radius of the turn starts out pretty big but then decreases ( gets tighter) it's also down hill and blind due to a hill on the right. If you are not familiar with it, it will catch you out. I'll bet you are right about the second rider target fixating on the rider in front of him and following him right to the guardrail.

I am going to ask you how you typically operate this machine.. when you first start off at what RPM do you shift, then at what RPM do you typically shift in subsequent gears? At what RPM are you typically cruising at? How many miles on the bike total? Answer those questions as I have a theory.

I doubt very much overfill is an issue, you'd have to overfill a ton past the sight glass... (how much oil was put in at last oil change?).....

There is a crankcase breather hose at the front of the airbox to channel gasses (can be oily) into the airbox and any "unburned oil" will exit via the smaller drain hose at the front lower part of the airbox (it has a filter in it below the airbox). That might accumulate a little oil which eventually will drip out.

FYI: recent trip from central TX to western CO and back I got 49.6+ mpg on 6 of 12 tanks. Those tanks were consistently the NM/CO tanks that were a) at higher altitude and b) on curvier more fun roads. I tend to smooth through the curves in a relatively high gear but clicking along pretty quickly. Lower avg speed though. Burning I-10 across west TX at 85-90 actual mph drops me into the 40 mpg area. Can't decide how big the altitude impact is though.

I can't either. I can also get good mileage on crooked roads in Arkansas, but I tend to ride a bit faster here. In Colorado I'm in tourist mode and usually riding with others who are in no hurry. Do I get better mileage because of the altitude, the more relaxed pace, or both? Dunno.

I am going on a 400 mile ride tomorrow...a straight shot down I-5 ..will probably average 75 ..I am going to stop in Vancouver WA and then 150 miles later
I am not going to hold my breath for much over 40 mpg ... but that is still awesome to ride a comfortable missile that get better MPG then a Honda Civic

It's both, the higher the altitude, the more relaxed pace the higher the gas mileage.

When you are running freeway at high speed, or twisty backroads where you tend to run lower gears to higher rpms you will see less gas mileage. Just the way it is. The more rpms, the less mileage you will see out of a gallon of gas.

I think few "try" and get high mileage, it's just a byproduct of their roads and normal riding habits. Some guys are what I call " revvers" and some guys are what I call " luggers" ( not actually lugging the bike but generally riding in the higher gears and at lower rpms) . If you've ever been to a rally the two groups are easy to spot lol. Nothing wrong with the riding habits of either group, and the bike doesn't care which group you are in. The nice thing about liter plus inline 4 s.
