1) Acceleration Sense: Where possible time your approaches to avoid standing starts. 2) Short-shift: Use more throttle to less RPM before upshifts. 3) Draft: Take advantage of large vehicles close to your desired speed. Leave reaction space but still within the moving eddys for reduced drag benefit.

Some engines doesn't like low rpm. I used to do that just to save gas but my mechanic screamed at me for doing that. He said some engines can take it and some engines don't. If you have a motor that has a huge torque low end then by all means but short shifting a 600cc 17k reving bike is gonna hurt it. Im a harley guy and I bought cbr600rr just for shits and giggle so i adopted my mannerisms of really short shifting my bike. Hell, in my harley i could slowly takeoff without even revving and immediately shift to 2nd, then 3rd, then 4th then 5th... All without revving past 1100rpm as long as the road is not in a incline. I borrowed an re interceptor 650 and i can feel that bike doesn't like shifting below 2500 specially if i have a pillion rider.

Setting aside the option of simply riding slower the two biggest factors to fuel efficiency I've found are: 1. Aerodynamic drag of big hard saddle bags (on my Tiger 800 or my dad's R1200gs we're talking 45mpg with, versus versus 55mpg without). 2. Limit acceleration and braking. That doesn't mean riding slowly, but simply carrying more speed into and through turns, to avoid having to brake hard into them and having to accelerate hard out of them. Staying in a higher gear helps here as well (lower revs, less acceleration out of turns). We may scoff at the idea of caring about fuel efficiency on a motorcycle, but who here hasn't found themselves a long way from a gas station, say 250 miles into a tank of gas, wondering if you're going to make it.

Fuel hauler nerd here. You'll note the labels say "*may* contain upto 10% ethanol" it's not for sure and has to be there even if the station buys ethanol free gas since the truck could have delivered e10 previous to that load. Another note is refineries and fuel terminals typically don't produce an actual "Mid-Grade" gasoline anymore and thus anything sold in between regular and premium is a mix of the two done at the pump. You'll see the fills at a station are colour coded. White is regular, red is premium and yellow is diesel. So if you're at a station with ethanol free premium and you buy 89 you have a 5%(ideally) ethanol content. You can check pump gas for ethanol by putting a small amount of water in a water bottle and marking the level. Then add gas and shake. Water and gasoline do not mix however ethanol is hygroscopic like brake fluid meaning it absorbs water. When you shake the mixture the water will strip the ethanol from the gas and mix with it. After shaking let it settle and note the water level vs the line.

Ethanol only eats certain rubbers. I forget which ones, but most aftermarket rubber parts for all types of vehicles are ethanol safe. The real pain in the ass is that ethanol does not burn as well as gasoline. E10 fuel reduces mpg's by 5-10%.

In many third-world countries I've driven through, I've often been recommended to buy "premium" gas even if my bike doesn't require it. Many of these countries also only have two levels of unleaded - no mid-grade. I figure this is for one or more of the following reasons: 1. The premium is simply made at a higher standard and in a third-world country you might worry that the lower grade (which is sold at the lowest possible price to serve the overwhelming majority of poor people) is made BELOW standards. 2. The premium might not have (as much?) ethanol. 3. It's just the grown-up version of the useless elementary-school myth that more octane makes you go faster.

One of the best “ cruise control “ devices I have ever used on a motorcycle and I’ve been using them since 1967 is free. An elastic band wrapped on the handle bar between the grip and the right hand switch and front brake lever block clamped to the handle bar. It provides enough friction to prevent the throttle from rolling back on its own even when you take your hand off the grip but yet is easy to roll back the throttle as you would normally when slowing and your wallet hasn’t felt a pinch. When one elastic wears out as they tend to do over time simply replace the elastic that was used to hold a bunch of carrots together from your grocery store. Free. It’s worked for me for over 50 years on a dozen bikes.

It is pretty nice to see 200 miles go by without a fuel light ever coming on. I also had to tape off about 3/4 of the already pretty small radiator just to see 170F water temps(it was 45F outside, which was part of that).

Great video! I replaced my stock exhaust system with a (much lighter) competition one, but kept a decent (titanium) muffler. After some basic fine-tuning the fuel consumption decreased and it suddenly had low rpm power. Granted, it doesn't look as nice as the stock system, but that's a small sacrifice i'm willing to take. Use the clutch! I disengage the clutch very early, and coast the entire highway exit (or entering traffic lights, crossroads, downward roads and so on) with the engine idling. With a decent timing, I rarely have to use the brakes and very lightly use the clutch to bleed off speed, while maintaining a high (but safe) cornering speed (so extra acceleration is avioded).

I have been impressed by almost all of the content this channel but for those not in the know, K&N air filters are prone to letting dust through if you ride offroad or other dry, dirty, places. Clean streets and tracks are the only place for a K&N filter. Foam and paper are the best choices for everywhere else. They are also way easier to clean /replace.

The only reason we have ethanol in our gas is because of corn lobbyists. The amount of emissions from growing the corn, refining the corn, and then burning it is greater than just burning pure gasoline. Plus it cuts in to our food supply, causing food to cost more. Ethanol only makes sense if it comes from sugar cane, like Brazil does.

They are working on a GMO based sugar beet that produces insane amounts of sugar when harvest, requires far less water or fertilizers compared to corn. Grows in about half the time, and can be grown in places normally not ideal for crops. The GMO sugar beets are fast becoming the main source for Ethanol production. Soon Ethanol production will outpace other forms of alternative fuels... and hopefully one day soon will become the main source of fuel for the internal combustion engine. With GMO crops not needing the same sort of land to grow, we don't need to worry about taking away the land we need for properly grown food crops. PLUS since 100% Ethanol can run in current engines (with minor modifications), we can use it instead of petroleum based fuels. Humans will need our plastics and other polymers to continue to live. If we can reduce our requirements of fossil fuels, and save the crude oil for production, we can substantially extend our supply. After all if our current rate of consumption continues (which it is only ever increasing at exponential rates), we are going to burn through our available supply of crude oil in about 50 years (BP says 52 years, before we run out).

Brazilian here. Ethanol is not the solution, right now ethanol is more expensive than Gasoline (here) and is by far less efficient (what sucks when you have a tiny fuel tank, like in a bike). We too add ethanol to our gasoline for "green" purposes, and when I said green, i mean politic, but it's not as bad as Europe importing palm oil from Indonesia that is literally deforestating their lands in order to keep with the demand from greener fuel in the developed world. Sugar cane is a crop that requires a lot of water to proper grow, right now we do have that water to dispose, but who knows what the future will be.

Summary: Get more fuel for money: Fill up in the morning / cold weather. Raise the pump hose above the tank to empty the last of the gas out of it. You paid for it already. General: Use only octane ratings your bike is rated for. Don't go higher or lower. Avoid high ethanol fuel. Don't carry more weight than you need to. Maintenance: Check and fix your spark plugs / carbs / injectors / jets / valve clearance. Check and clean or replace your air filter. Keep your tires inflated properly. A few PSI over is OK. A lot over is dangerous. Riding style: Ride at slower speeds. Avoid acceleration and deceleration where possible: accelerate slowly, stop slowly and early. Lane split to maintain speed. Use cruise control / throttle lock. Engine brake rather than using the brakes or coasting in neutral. Ride lower and closer to the bike. Modifications: Remap fuel delivery for better mileage. Get low rolling resistance / stiffer tires. Will decrease grip. Get a lighter sprocket. Get a lighter chain. Will require more maintenance and attention. Change sprockets to lower all RPMs. Less acceleration, maybe higher top speed. Get and use a throttle lock if you don't have one. Gear: Use a tank bag and or tail bag rather than saddle bags / panniers. Wear a full face helmet. Best bang for buck: Sprockets and chain. Ride slow, maintain speed. Keep your air filter clean.

To be fair, most ethanol blends are usually better than pure gas, as they evaporate better, which in most cases results in higher thermal efficiency. They also deliver slightly higher octane ratings. Both effects are more prominent, when on high loads and especially when on high rpm. The water attracting part can be useful, if used correctly, as it binds water, which won't "harm" anything as long as it is bound. The problems begin, when it is saturated.

Power commander with wide band o2, 520 chain and aluminum sprocket, lighter after market exhaust, and a bunch of other little things, you know typical upgrades... I saved roughly 30lbs of weight on the bike, and improved (in ECO mode) 10 MPG over stock... SO if I only ever rode in ECO mode, I would recoup my money in roughly 20k miles, or about 2 years, with the miles I ride. BUT since the mods also allow for an improved level of performance over stock, I do NOT ride in "ECO" mode unless I need the range. The original MPG was about 35, with the new maps and "upgraded" parts I can get very close to 50 MPG. SO instead of getting 160 miles out of a tank, I can get closer to 225 miles. For longer rides it is godsend having the ability to improve the millage so drastically, while still being able to have the extra power and performance if I so choose. All by pushing a button and switching maps. The down side of the "ECO" mode, is a huge lose in power, and very "boring" engine performance. Of course, by hitting that same button I can get "full power" mode, with about 140 HP on tap... It's can be very exciting... Of course that comes at a sacrifice of getting much lower fuel millage...

@@Roy_Godiksen Fair enough, and easy to misinterpret. Fuel economy refers to the economy of fuel though, meaning distance traveled vs volume of fuel. Most people only really care about this in terms of money saved, since volume of fuel is seen as $/gal, not necessarily gal/tank. So it's understandable that talk of fuel economy is mostly seen as a consideration of total monetary cost of gas, and thus of mileage, not the fuel "cost" of mileage. There are also people who care about fuel usage outside of it's monetary cost, and might not worry too much if they only break even, or even lose a little.

I live and ride an 800gs in the desert, dry dust all the time. From all the sleuthing I've done and the local Motorrad mechanics I've talked to, compared to paper filters, K&N et al. lets a bit (too much) of that fine particulate matter flow through and is bad for the engine in the long run. That's how you get the power increase, bigger filter pore size, more air flow! But, if you live in Vancouver or someplace with less dust on the regular, you're probably good with a K&N.

Closed loop F.I bikes: (i.e. with lamda sensors) When you are riding for fuel economy, will not make much difference, cause the throttle valve is already blocking most of the air going in. A modern ECU will measure the mixture and adjust Open loop F.I bikes with some sensors (no lamda sensors): IF they have a map sensor (measures atmospheric pressure inside and outside the airbox), will adjust the fuel mixture for less air drawn, although less accurately, so less incoming air is compensated Carbed bikes: Less air will make the mixture richer BUT, fuel is drawn into the cylinder by the vacuum it produces, so less air going in will reduce the fuel sucked in, some carbs have tricks to compensate, some dont

Drag is the main factor in fuel economy. Rolling resistance and engine/drive train friction will increase roughly proportionally to an increase in speed and engine rpm, meaning that the related fuel use would be roughly proportional to distance traveled. However, air resistance increases exponentially with an increase in speed. ("air resistance force is approximately proportional to the square of the velocity, v2. In other words, twice the velocity produces four times the force.") That's why top speeds are ultimately limited by available horse power, and that is generally proportional to the amount of fuel being burnt. Rolling resistance aside, for a bike to do 100 mph, it requires 4x the power of doing 50mph and 16x the amount of power to do 25mph. Tuck yourself down over the tank and pull your knees in as much as you like, but if you're worried about actually making that next gas station, slow down!

Back pressure is only necessary (and useful) in a 2 stroke engine, where the combustion stroke is shorter and the fuel (being less atomized) burns slower. On a 4 stroke engine it's unnecessary and will cost you power and efficiency. The myth that 4 stroke engines need back pressure comes from people who put huge 3" exhausts on their vehicles and lose power. This happens because of the venturi effect, gasses flow slower in a wider pipe and faster in a narrower one (until restricted by back pressure), that faster flow in a correctly sized pipe helps draw out the exhaust gasses.

Knightmare I disconnected the exhaust after the last catalytic converter on my v6 accord for a day. It lost a shitload of power down low. Didn’t change the pipe size or anything, but those 3 mufflers which were bypassed DO help. On my 4 cylinder CBR250, I changed out the original muffler for a long glasspack. Again, didn’t change pipe diameters before the muffler, and I did rejet it richer, but it lost low end power and fuel economy. Backpressure does help if done correctly, so stop parroting engineering explained with his “stop saying engines need backpressure” video. Is your engine going to blow up without backpressure? No, but it will affect how it runs.

Back pressure on a 4t is like saying that 2 valves works better than 4. Engine efficiency is like not "how much water flows, at a given mass, it's how far away the jet is landing". Back pressure is like adding a screen in front of it. Two valves engines have better torque on the lower rpm range, so longer gearing is more suitable. That's what I'm after myself, longer gearing, for lower rpm coasting. I'm not interested in faster acceleration, my bike has only 11hp...
