Short guide to get a lot more power out of the EFI 49cc Kymco scooters. This is for the Compagno 50i (New Sento). I can't vouch for how many 49cc EFI kymco have this restriction but it may be many. Very very easy to do.
Remove seat bucket or Maint. Door under seat.
Find the screw that looks like an idle screw on the throttle body.

This screw makes the throttle only go to about 50% throttle as you can see with the Diagnostic tool readout before and after stop is removed.

It's that easy!! The Compagno 50i is a sweet little 4t 49cc. Check out the cylinder head on this thing.

Roller rockers and 3v !?!?!?!?! Kymco whyyyyy not on all the air cooled bikes!?!??!
Anyway not even sure if anyone on here owns a Compagno, and since we don't get many models in the U.S. I have no clue how many bikes share this engine globally but thought it would be useful.
-
Cool demo Bettin. Does the Campagno 110 also have the 3 valve set-up?

-
Yeah the 110 is a great bike it's faster than the Agility 125.
-
thanks for sharing! how does this scooter ride? does it feel better built than the agility and super 8?
kymco is going to be lowing the price to gain more interest in the market for these two scooters
-
The build quality of both the compagno 50i and 110i is far superior to the mainland China Kymcos. Performance on the 50i is a solid 40mph once derestrcted, but I've had customers averaging over 100mpg. The engine is on a whole other level compared to the qmb based agility engine, 3valve with roller bearing rockers and efi. The 110i is actually my favorite small engine Kymco on the lineup right now. I'm 6'1" and fit on the compagno better than the like or agility, and it's performance is almost as good as a 150cc, 4 valve engine with roller rockers and efi is a really awesome combo for a 100cc scooter. I don't think anyone on here has a compagno, sadly. Also the newest batch of 50i's we got came fully de-restricted out of the crate (technically illegal) for shine reason, throttle pull and smooth boss. One last thing about the compagno it's the gas tank is under the floor so the seat storage kicks butt and keeps the CG low.
-
kinda what i figured, and the price reflects that. same thing with the movie 150. awesome scooter and is loads smoother than the agility or S8. the extra $1k scares people.

I just bought a 2013 50i in Kansas. I had them turn that screw when I bought it at the dealer. They actually took it out. Mine is still somehow restricted because even though it gives more throttle it doesn't go faster than 30 mph even with more throttle. It seems to go 30 uphill and not even much more than 30 downhill. I took it up a couple steep hills and it had zero problem doing the hill at the same speed as flat ground (30 mph max).
Wonder what restrictions are still on the bike? Variator spacer or maybe cdi is rev limiting it? Either way, not much need for full throttle with the current setup since more throttle basically is doing nothing.
Dealer did mention that since Kansas is one of the rabid 30 mph max states-- he said there were like 6-- they have to restrict moped legal scoots in these states. He said all the honda and yamaha bikes don't bother which is why they are all licensed as motorcycles here-- ie metropolitan and zuma.
I just really wanted the fuel injection on a moped legal because i hate messing with carbs.
What do you think is restricting it now? Guess I can call Kymco and ask, get the right parts to derestrict it and go from there.
-
Sounds like they didn't take out the variator restriction. All states have their own moped laws. Oregon it is 30mph too but no cops look for mopeds going faster than 30, hell I had my zuma doing 60+ and never got hassled, with moped plate still. If you want it to go 40 they HAVE to do the variator boss.
-
Boss/rollers (5.5 gram)/Malossi red or purple Contra spring.40-45 mph.

I just bought one of these from ebay.

Hopefully that is the right part then i will replace that and if that gets me to 40 great if not then maybe cdi? Probably best to call up Kymco and see if they can clear up the restriction and just do what is needed. I don't need 40-45 just a strong 35 would probably be fine.
-
Ummmm idk if that's the right part, how come you ordered that one? Also there is no cdi replacement on the fuel injected scoots, at least not easily installed. It's tied into the ecu.
-
I figured it was 7 bucks so why not get it on the way and if it is the right part i will put it in. Wrong part, oh well 7 bucks.
-
It is the right part. It's a new part number for an older part.
That boss supersedes the one used in the S 9, and the Sento. The old number had KFAS-900 as the suffix.
I found it sells around 30 bucks everywhere else... Nice score! ;)
-
Perfect, I hadn't had time to cross, I just remembered the ones we have in stock being a different designation. Good call Zombie!!! The strange thing is the last batch of Compagno 50i we go were fully de-restricted from Taiwan hahah. His sounds restricted tho. It's a shame that's the only 50 that got that engine, super deluxe 49cc motor. 3v, EFI...... great combo.
-
I'd like to find a junker myself.
W/ a little massaging i'd bet 50mph could be done reliably. 8)

Kymco parts showing 2009 sento part number 2105-KFA5-E00 and compagno 50i 22105-LEA3-E90
Seems by looking up both parts they are both 20x38 mm so I'm going to go with it being the same.
Bottom line is i can pull the old one out and if it same length it will work?
-
Look up!
The first post on this page...
I looked it up for you (no charge). It's the same part, and it will work. :-*
-
Sweet. Thanks much!!
-
Took off the cover and my roomie hit the nut with the impact wrench. Pulled out the restricted sleeve which was same length as new part, put new one in, put it back together. Everything fine. When its not so cold I will take it out for test drive.
Thanks for all the help.
-
That's why were here. ;)
-
Nice, you'll feel like a rebel pulling up next to cops!!! They'll have no idea!!!!
-
Took it out on the maiden voyage today. Was not fast, in fact it seemed a bit slower. Of course it was cold here like 30. Before on hills and such it would only go 32 tops down, now I saw 37 or 38 maybe? I didn't stay on it since this engine has like 15 miles on it. I'm wondering if my roomie tightened things down a bit and if the parts will loosen up and work better as it gets warmer and more broke in.
-
Hmmm yeah 15 miles on that engine everything is still tight. Normally my fat ass gets a solid 35 flat land.
-
I'm 208 pounds myself. It was not wanting to go faster than 28 at first on flat but I think it loosened up. I'm just gonna ride it awhile and go from there.
Basically as it stands now it will get to 30 mph, sort of slowly. It struggles to go faster than 30 and will go 35-37 mph if you go downhill and then it seems to be able to maintain faster than 30 mph speed but it needs to be going downhill first. I'm wondering if there are any other restrictions on the scooter other than the throttle screw and the drive face boss.
-
Well I picked up an electric impact gun for 40 bucks so i wouldn't have to rely on my roommate. Took off the variator and took out the old rollers which weighed 7 grams on my food scale and replaced them with 6 gram sliders.
Will have to wait until it is a bit warmer to find out how it worked. Everything seemed fine running on the stand in the garage.
I think the 7 gram rollers was rev limiting me and hopefully I will see more revs with the 6 gram sliders.
-
Perfect man! Just make sure to use a little Blue (Non-permanent) loctite on the nuts of the variator. That motor is 3 valve so it should respond very well to more RPM.
-
I actually test drove it just now-- 23 degrees lol.
I let the engine warm up and drove about 5 miles and got a cup of coffee and warmed up. Then drove it around some more and went home.
With the 6 gram sliders on the way back I was getting about 32-35 on flats, slowing down to 32 or 30 on bigger hills, and about 35 going down. I think the fuel injector is smart enough to rev limit, probably about 7500 rpm since the specs say best power is at 7500 rpm. With the 7 gram stock rollers it would go 37 or a little faster downhill but it was slow as a dog to accelerate and 28 on hills. I'm really super happy with the pep and acceleration of it with these 6 gram sliders and I plan on leaving it this way for awhile. I still didn't air up the tires and they are probably 21 and 28 front rear since I never messed with that. When it warms up I will probably go like 32 psi on front and 35 psi on rear and see how they do. Remember whole bike now has 59 miles on it. After a couple hundred miles and warmer weather I bet it really handles its own in 30-35 mph traffic.
I'm like 208 pounds and its cold as hell out here so all things considered I'm really super happy with the way it is riding.
I didn't use any locktite but I hit it a few extra times putting it back on with the electric impact. Somewhere I read it spins the opposite direction from the direction the nut tightens so I hope it will stay on there. Stock it had no locktite on it.
Also mileage seems extreme, probably in the 100 mpg range.
-
That sounds great, and what you said about tire pressure, and air temp are correct. The bike will have More pep, and better speed w/ better conditions.
I'm really happy for you. Nice job!
-
Thanks man for all the help. Appreciate all the replies. I did ask kymco to call me back and my service dept at dealer to figure out how to make it faster. They never got back to me and wanted like 80 bucks for 10 minutes work. Did it myself, learned, and plan on trying to do my own maintenance, except maybe let them do the brakes.
I would recommend this scooter to anyone who wants a moped legal scooter in kansas since the honda mets and ruckus are not restricted but tagged as motorcycle.
But for the money difference I think a used carb type kymco might be better fit for most-- i just wanted fuel injection so i would avoid screwing with carbs and for easy starts.
Total mods-- replaced variator drive boss face from restricted to smooth-- 7 bucks shipped, removed screw on throttle free, and replaced stock 7 gram rollers with 6 gram sliders-- 23 bucks shipped-- total cost to de-restrict 30 bucks-- well ok, 45 bucks for an electric impact and 17mm impact socket.-- 75 bucks. Still cheaper than one service from dealer and now have my own tools.
-
I love your attitude. You are a born scooterist. ;)
Your sliders will out last 7-8 sets of rollers as well so you can take that cost right off the top!
I was going thru one set per month of the cheap ebay rollers, and 2-3 sets of Molissi/Polini a year. My sliders have been in the bike for almost four years, and they still look the same as the day I installed them.
One of the best value parts I have. ;D
-
And the saga continues. I got my paperwork and it says right on it 3.6 bhp, and 3.5 is moped in ks and 3.6 is motorcycle.
Dealer typed me out letter saying it was factory restricted to 30 mph if that doesn't work i have to get motorcycle license.
Dealer told me if it is a motorcycle they will help me make it go as fast as possible. That is pretty cool at least.
So I will keep posted as to what can be done etc. He said the fuel injector might be programmable for one thing.
-
Tell DMV to put the bike on a Dyno. My gut says 3.2BHP at the rear wheel is more in line w/ reality.
My gut also says you will never get away w/ telling DMV what to do... never mind.
-
It worked out. Long and short of it was-- I was very nice and polite and the tag guy gave me the benefit of the doubt and tagged it moped.
-
The pet rattle snake, and six gun on your hip had Nothing to do w/ it, im sure... Score one for the good guys!
-
Just got a Compagno 50 in last week. Put it together and it run about 30mph on flat. Im 200lbs.
It has zero restriction from the factory so hopefully it looses up a bit and gets 38-40mph 8)
