I have had this scooter for two years, one of the reasons for the low gas range(besides the small tank) is the high rpms on the highway. Is there a way to lower the rpms at highway speeds. thanks Jim

what's your speed and rpm's?
also what size rear tire do you have on?

whats your tire pressures?

OAD: Riding with motorcycles(I have been riding since 1965) on an expressway we are some times doing 65-72+ mph, the engine(and belt and rollers) which is stock and the tires are stock is into the 5000-6000 range. Tires at recommended pressures. This is a very low mileage (3000 mile) scooter-its all stock. I keep looking for a high gear. Is there anything I can do with the rollers when I change them? Anything else? thanks Jim

yes you can change the rollers to a dr pulley slider.

a lot of folks use the 17 gram slider and others like the 16 gram ones.

A little over 70 MPH I am around 6200 RPM. All stock.

Been that way for over 42,000 miles.

Better fuel range on a MP# 500
Yes the rpms are up there and that eats up the gas. What would different sliders do for the bike? I have to stop more for gas and that is a problem when riding with motorcycles with a longer range. thanks Jim

I'm confused why you think the rpms 'eat up the gas'.

At highway speeds your main 'opponent' is drag through the atmosphere. You need power to match that drag. Power is RPM X Torque - and your torque has limits.

Yes, the highest speeds will eat up the gas, but it's not because the rpms are high, it's because you're then extracting the maximum power from the engine. If you geared down the scoot by (for instance) adding a larger diameter wheel and tire then your speed would drop. Upping the gearing won't help your top speed or your fuel economy at that speed. It *might* help your fuel economy at residential road speeds, but that's pretty damn good anyway.

The only ways to increase fuel efficiency are to decrease your drag or raise your engine efficiency. Changing to a heavier roller will decrease RPM, sometimes getting you into a more efficient regime, but at highway speeds, rollers are pretty much slammed to the outside of the variator anyway. DR Pulley sliders can increase the gear ratio because they can go further out, but most people put them in because they like the additional acceleration they give at lower speeds. My recommendations would be to:

1) get a windshield
2) put in some DR pulley sliders at about 2 grams lighter than your stock rollers
3) change your belt

Windshield will help with drag, the DR pulleys will increase the ratio and a new belt, being wider, will also increase the ratio.

But all this will only give you about 5-10% better fuel mileage. Means maybe another 10 miles per tank. If the problem is not wanting to stop as often, then you might be able to bodge a secondary fuel tank onto the bike, or carry a spare can in the pet carrier.

Most cruising motorcycles have a substantially larger fuel tank than your MP3. Isn't that at the root of your issue, rather than RPMs?

Surely it is the throttle position that effects the fuel consumption more? The drag at 70 mph needs X horsepower regardless of rpm?

mp3 500 more range
Thanks for the help with this. I do have a windshield and carry a spare can of gas. -and yes the fuel tank is too small so I am looking for another way to get better range. If I were to change the belt and use sliders what are the recommendations for better gas range. Jim

I personally love the low revs when cruising, when I had my 500's I put in some heavy sliders, 21 gram I think or was it 23 lol. yes it lost take off speed but I found it a very satisfying lazy way to ride. it felt much less strained and more of a grown up feel. ow and the mpg was slightly better not by much just 3-4 mpg

gas range MP3
Bsf: thanks for the information. I am waiting for additional advice-this maybe the way to go. Jim

Do not fit the fuzzy washer modification. This will raise your gear ratios.
Keep your tires pumped up. Fit a smaller screen for less drag. Keep the speed down to under 60 mph.

You could gain 10% mpg or more.

all the tuning you do is not going to give you the huge mileage jump you so desire.

look the bottom line is the faster you ride the lower your MPG's

So to extend range you have to lower your speed.

Now if you want more range you need a bigger fuel tank. period.

compare your MPG's to others you ride with and I bet your a lot higher than they are but they have the advantage of a larger fuel tank so their range is more.

MP3 more fuel range
I am just looking for options to increase the fuel range. Do not expect a large increase in mileage. thanks Jim

If you don't have a top case, you can add a tank to the back of the scooter like some guys do for the cannonball. You could more than double your range.

Any links or info on how to search the larger fuel tanks. thanks Jim

I tend to find that the range gives me that time to stop and relax for a few which very few people do nowadays. When I ride about 270km, I have or 4 stops with once fill up close to my destination. With those stops I drink water to stay hydrated, stretch my legs and back, and relax for 10 to 15 minutes. Riding is a lot harder mentally and physically than driving a car, so I don't see a big deal with stopping. I tend to average about 230km on a full tank, but my speeds and throttle input are never for economy.

If your planning to use your MP3/500 for Highway Speeds vs around town all the time. You should get a Motorcycle with multiple cylinders.

When I ride mine on the Highway, I stay at 5000 RPM's which for me is about 60 MPH, and this is for short runs of maybe 50 to 100 miles.
Push it to hard for long periods of times, you will start blowing Oil and damage your piston. Be sure and run a 5W/50 Motul Grade of Oil for extra protection that handles the high heat.

Strictly speaking I can only report on the MP3 400 but I can definitely say that Dr. Pulley weights did reduce the high speed rpm on that model and almost eliminated the tendency to hit the rev limiter. If you are concerned about fuel consumption I would recommend weights no more than 1 gm lighter than stock rollers. If you go any lighter the increase rpm during acceleration will cost more fuel than you can save at cruising speed.

Yes there is on all the variants of this engine that I have tried. Usually its only reached under favourable conditions and it produces a kind of mild on-off stuttering effect.

Have 55,600 miles on my MP3 500 using 5W-40 AGIP Oil. Checked my oil after 2,500 miles and I did have to add 250 ML. Not sure why a thicker oil would be needed.
Does Piaggio recommend 5W-50 oil for the new MP3 500's?

I do agree keep the RPM's down. I have Dr. Pulley 16 grams and am at 6,000 RPM most of the time.

Almost all motors have rev limiters these days.
