I recently bought a Kymco Vitality 2 stroke 50cc scooter, I dont know a lot about the kymco brand. I am looking to mod it to get a little more speed out of it, right now everything is stock. I dont know if the CDI or variator has been de-restricted either and I dont know how to tell if it has, if someone could give me some info on how to de-restrict this scoot I would appreciate it. This bike will go about 30-35 on a flat surface, it suffers greatly on take off and up hills (it feels like I'm riding a yamaha razz or honda elite).
Also I have done google searches and cant seem to find any websites to get parts specifically for the Vitality 2t, all the ones I get are for parts for the 4 stroke model, does anyone have any links to help me out?

Hello God Welcome to the forum Ha! I think the vitality has alot in common with the people motor wize,but not sure if the same.There all kinda similar,what year is it,the older model cdi have a green wire at the bottem just unplug and done if newer must replace.The veriater boss if restricted should be replaced.The 30 to 35 is a sign you need some derestricting unless it's not running well.Should be able to add another 10 mph easy.After that airbox and pipe for the 50+ range takes a bit more tuning for this level.might have to go talk to your local dealer for derestricted parts they usually carry them.Here's a sight i like but little hard to nav.but has some of the best deals. http://www.sip-scootershop.com/EN/main/base/Results.aspx?d=(sco,ape,lam,old,px,sma,max,atv,mot)&s=b61998e3c9484103a434dcc2a1bec5b6&a=1&sort=0&oc=646694d5bf884654af694cb63b46d8f6 (http://www.sip-scootershop.com/EN/main/base/Results.aspx?d=(sco,ape,lam,old,px,sma,max,atv,mot)&s=b61998e3c9484103a434dcc2a1bec5b6&a=1&sort=0&oc=646694d5bf884654af694cb63b46d8f6) . check it out.

Mine is a 2002, I dont know when the cutoff year is to be able to de-restrict the CDI but I will look anyways today when I go out to see if there is a gree wire on it.
Also, I have put well over 300 miles on this in the past two days, so I dont think the lack of speed is related to how the engine is running.
Could it be possible that the muffler is plugged up? I know when I ride it about 20 miles I can stop for a break and I could seriously fry an egg on the tip of the muffler were the tailpipe comes out.
As for my dealer, well they couldnt tell me what size roller weights this thing has in it, so I think I will stay away from them. They are the only kymco dealer within 100 miles of my location.
-
Great the dealers are usually the best place for the drive boss. They do run a bit hot but as for the age may need to look at that pipe could use a good cleaning. That old a bike should be an easy one to derestrict(the cdi) don't know your model well enouph to give you deffinet answers. Take a look at the cdi. Some one should be able to help.
-
...god...welcome to th' forum!!
;D
..can you post a pic of your cdi??
-
All I know about the CDI is there is a green wire and if you cut it the bike wont run, the CDI has 5 wires on it.
-
..alright then, what are the colors of the wires?
..on each connector?
-
The color of the wires are
Black/Yellow
Black/Red
Blue/Yellow
Green
Black/White
There is only ONE connector.
-
I,m not familiur with that color scheme,but instead of cutting you can unplug the wires from the connector with a small screwdriver or ice pick. From the bottem you will see an opening to one side or the other insert tool and pull and wiggle they should pop out. With a little trial and error should be able to figure it out. You will be able to reinsert them without any damage(If they came out that way :D) My guess the black and white. Good luck
-
How can I clean out the muffler?
-
The best thing to do is remove it. Inspect if balls of carbin are falling out It will need some more attention. If it weighs unusually heavy you have another problem(wet fuel and oil in the pipe) I try to shake,tap with a rubber mallet and blow compressed air through it. If you have access to a parts tanc you can soak it.Won't remove carbin,but everything else.If you have a drill and some braided cable you can fish it through and give it a few turns. For the realy backed up pipe heat is your only option (torches) heat evenly from one end to the other(red hot) Have heard of othere tossing into a bon fire and dig out the next day. If you have welding skills you can cut open and clean,weld back together. There is also the new pipe option ;D Just make sure air is moving freely from point a to point b. and all should be fine ;)
-
The other night I hit it a couple times with a rubber mallet while holding the throttle wide open and yes, a few small bits of carbon shot out the back. I think the best thing I could do is try putting it in a fire, I have no access to torches or welding equipment, not to mention even cutting tools to get the muffler apart. I am eventually gonna replace it with a performance exhaust.
-
Take it off and check it out. If going to replace just clean it the best you can. Sometimes a couple beatings is enouph. :D
-
yea as soon as I get some extra time, I am going to take the variator off and inspect the rollers and belt. Thats when I might take off the muffler and clean out the exhaust port on the engine too.
-
That should help ya out allot, i was going to suggest those things also,sound like you got a handle on it now. Post your results positive or negitive. Good luck
-
Well I got the side cover off tonite and checked out the insides, there does not appear to be a restrictor on the variator, unless I dont know what I am looking for. (It pretty much looks like everyother variator I have saw, same as a 4 stroke)
The rollers have flat spots, so I will be putting a fresh set of 7g rollers in soon. The belt is in good shape. And I still cant figure out the CDI unit if it has a restriction or not.
-
..that's been a tough one, god...
..there was another guy here, a while back, with the same issue on his v50...
..and i'm not sure anybody ever got it figured out...
-
If the (boss) doesn't have any grooves or any thing but smooth and level throught the ver. it should be derestricted,sometimes a washer on the back side can be your restricTion.None of that,then you should be good. New rollers will help,I personaly replace the belt when in there sometimes the wear is not noticable,the belt may be streached. Don't hurt to have a spare and you are sure these are not any of your continuing problems if they still exist.
-
..i carry a spare belt and the tools needed to replace it...
I still cant figure out the CDI unit if it has a restriction or not.
..that's what ain't been figured out...
..i believe the dude replace his, and performance increased...
..i'll search for those posts...later... ;D
-
The BOSS has no grooves or washer on it. its smooth.
As for the belt I was gonna go ahead and get one too, that way I dont have to take it apart again anytime soon.
Let me know when you get that CDI figured out.
-
Your on the right track. just don't know that cdi maybe a pic would help.
-
I dont have a digital camera at the moment, besides I think I got the CDI restriction figured out..... Now my next problem is finding a performance exhaust system. The local dealer has no clue were to get one either, hows come everyone else can seem to mod these scoots, but I cannot even find a website to buy parts?
-
Also someone left me a link to a parts site, but it is in europe! I live in the US and that does me no good.
-
Check these guys out. http://www.sip-scootershop.com/EN/main/base/Results.aspx?d=(sco,ape,lam,old,px,sma,max,atv,mot)&s=b61998e3c9484103a434dcc2a1bec5b6&a=1&sort=0&uc=(1d5dedbf24d143ac9db25ce00b5e13b5) (http://www.sip-scootershop.com/EN/main/base/Results.aspx?d=(sco,ape,lam,old,px,sma,max,atv,mot)&s=b61998e3c9484103a434dcc2a1bec5b6&a=1&sort=0&uc=(1d5dedbf24d143ac9db25ce00b5e13b5))
-
Also one other question, I have the chance to pick up a performance 99mm variator from a store, will I need the 18mm or the 21mm model? And I think that they are talking about the diameter of the center hole of the variator.
-
ART> that place is in europe, you cant even read half the text on the screen
-
They have great shipping prices and service i use them all the time.
-
Try the new link it's on the page you need ,it's a little hard to navigate. at the bottem is a setting for language. If nothing else look at the pipe you want and google it for a local shop.
-
ok, I get two choices and neither one of them are english. Anyways, i'm not gonna order from them I think I will drive 100 miles to the nearest shop and see what I am buying that way I know it will fit.
-
If you can find the tecnogas r1 It has been one of the better ones
-
Here's another http://www.mhr-usa.com/tecnigas-performance-scooter-exhaust/next-r-chrome/tecnigas-next-r-for-kymco-cobra-yup-vitality-50.html (http://www.mhr-usa.com/tecnigas-performance-scooter-exhaust/next-r-chrome/tecnigas-next-r-for-kymco-cobra-yup-vitality-50.html) . Not my faverite store.
-
now once I upgrade the exhaust will I need to get a bigger jet for the carb or will it run better with the new exhaust alone?
-
You will need to upjet. I don't have your model i don't know whats recomended. If doing the airbox also a #95 main is a common start on most 50cc 2t's
-
ok I will keep that in mind. Now if I dont change the jet will it still run good with the new exhaust? or will it run bad? What I am asking I guess is, will the performance stay the same as far as speed and power goes untill I upjet?
-
With these small motors changing one thing affects another. You have to do plug chops after each part is changed to see how your motor is performing. You run the risk of running too lean and that can damage your motor.
To answer your question It is hard to tell. If doing the pipe you should do the open air and upjet for best performance + plug reading. After that usually the roller weights to ballance things out. Of corse at this point you will probably even Want more!!! ;D
It seems that others who have tried just the pipe have had problems getting things just right.
-
...what is it with that...
..you just gotta increase air intake, and fuel delivered, to be able to benefit from a "pipe"....
..HELLO??
???
-
Ha! Some of us are just GEEDY, wanting top performance and stuff. ;D :D ;)
-
I was wondering can someone tell me the size of my belt, I have a 2004 Kymco Vitality 2 stroke, my local "dealer" knows less about my scooter than I do apparantly. They cant look it up by the make and model because they still use catalogs to order parts from....And also is there a performance belt available ??
-
..there a cpl of belt sizes that will "work"..
..i believe the oem is a Bando, 23100-KEB7-9000...
..most of the 50 cc kymcos use the same length belt...
..i've found that a 729-17.7-30 belt is about 1/8" longer, and will allow for a faster top speed, but may also require some cvt tuning for optimum performance..
peace
-
I would go with the gates 729 The molassi http://www.sip-scootershop.com/EN/Products/M6111153/Belt+MALOSSI+Kevlar.aspx (http://www.sip-scootershop.com/EN/Products/M6111153/Belt+MALOSSI+Kevlar.aspx) . claims to be 738 9 18 28 But is in fact shorter than the stock bando.
-
if I used the longer belt will I have to use heavier weights in the variator? it comes stock with 8.5 gram. Also, I clicked on that link and I have been to that site before and its not in english but either way I can look up the belt size and get it elsewere
-
..most likely lighter weights (which you would like even with a oem belt)
-
Ya no one else had it in stock,and not at that price. Sad but true most the best prices and parts are in europe if you spend enouph time on there site it's worth it!!! Check this out for malossi belt sizes. http://malossi.com/Archivio_Files%5CMONTAGGIO%5CDIM%20CINGHIE_001.pdf (http://malossi.com/Archivio_Files%5CMONTAGGIO%5CDIM%20CINGHIE_001.pdf)

Hi guys,
i just bought a Kymco Vitality 50 2T, 2008 model. It runs fine, but is restricted to 45km/h. I have read the posts on this board (btw, thanks alot for all your time and effort, it really helps a noob like me:) and I understand that there are two mods i can do; replace the vatiator "boss" (which looks easy enough) and de-restrict the CDI. Since i am not trying to maximize the performance of my scooter, i only want it to follow traffic at about 55-60km/h, i figure i'll try to de-restrict the CDI before i go about ordering parts. I have seen lots of pictures and youtube video of the procedure for other models, but none spesifically for the Vitality 2T. Before i go about cutting anything, i'd like to know if it is the same procedure as shown on the scootertherapy site :
http://www.scootertherapy.com/cdiboxcutpage.html (http://www.scootertherapy.com/cdiboxcutpage.html)
If not, where can i find the correct way to do it? Also, someone mentioned that it might be just pulling out a wire from the CDI connector? I figure if it was that easy there wouldn't be a guide for cutting into the CDI, but again, there might be a difference between models.
Looking forward to an answer:)

G'day marauder, welcome to the forum, you have come to the right place for info on kymco scooters. I am not familiar with the vitality, but I am sure someone will see you right. With the cdi derestrictions, they vary from model to model. My ZX50, I had to bridge two wires to short the rev limiter, I think the agility needs a cut through the cdi itself, (to cut a wire inside) and I think the people have a wire that needs to be unplugged. So there are different situations for different models. Start a new thread and if you can post a pic of your cdi and/or list the wire colours so that people wil be best able to help you. Derestricting your variator is a good first step, it basically gives your scoot another gear, read same revs-more speed. To improve pickup you can try playing with the variator roller weights, lighter weights will enable you to take off quicker.
-
..yeah, welcome to th' forum! marauder!!
..these scoots were designed to run without restrictions..
..you can open your scoot up to where it runs it's best, then regulate your speed with your wrist...
..it's sometimes very nice to have that extra bit of "oomph" when you need it...
;D

Thanks for the warm welcome guys:)
I've been looking for a drive boss replacement, and i've found this :
http://gy6-performance.fr/drive-boss-face-spacer-gy6-p-605.html?osCsid=6cfe4dc1cd6bdd0dfbc7d787111e9f4f (http://gy6-performance.fr/drive-boss-face-spacer-gy6-p-605.html?osCsid=6cfe4dc1cd6bdd0dfbc7d787111e9f4f)
Can anyone tell me if that is the right size for my Vitality? It says it fits the Agility model.
-
Here's another give them a call to confirm. http://scootertherapy.mybigcommerce.com/products/Kymco-Boss-Drive-Face-%28Clutch-Boss%29.html (http://scootertherapy.mybigcommerce.com/products/Kymco-Boss-Drive-Face-%28Clutch-Boss%29.html) 1-608-255-1520

Can anyone tell me if that is the right size for my Vitality? It says it fits the Agility model.
..yeah, they're the same...
-
Thanks again:)
Since i live in Norway, i will order the part from France. I will have to think about it though, as the p&p is 20Euro (the part
is only 10Euro). There are also some special VAT and customs rules in Norway (they're crazy protectionist). With VAT and
the handling charge through customs here it will probably end up costing me around 60 Euro's for that one part.
That's pretty steep for what is essentially a piece of steel pipe:)
-
..you can have the step machined off your oem...and i believe the length shortens a bitas well..
..i have those specs here somewhere........

Hi guys,
just a little update from me. I ordered the part and got it on saturday (it cost me 30Euros, they were nice enough to mark the cost low on the package so it got through customs). I followed the guide, and here are my observations :
- You definetely need an impact wrench. I tried it first without, and it's just not possible. With an impact wrench it took 2 seconds. What i did is
rent a garage with tools from a school nearby. I know there are other places where you can rent garagespace by the hour. Anyway, 1 hour should
be enough, i used about 45 minutes total.
- The guide is spot on, just follow the instructions and you can't go wrong. On the Vitality you need to remove or partly remove some
of the plastic trimming to do it, but its just a couple of screws.
- The only problem i had was getting the belt back on ("slip it back on" as the guide says). Well, it took me 10-15 mins but i finally got it on.
So be prepared to use a little time, and don't give up. A tip is to put a screwdriver into the little hole in the bolt the impact screw fits on to.
Then use the screwdriver as a lever and work the belt on. It worked for me eventually.
- I wasn't able to test the top speed today. it's raining and it's pitch dark. I live in a city full of potholes and tram tracks. The road is also full of
slippery leaves, so i didn't want to push my luck. However, i got it up to 60km/h easily. Before i could get maybe 55 downhill. So i expect it got me
around 8-10 km/h extra. But, the best part was the engine revs. It's a totally different experience. Before i felt like i was killing the scooter when
i bottomed it out, now it's running much much slower and quieter. It's obvious the engine has loads more to give, and that the scooter is restricted
elsewhere. I think the CDI isn't restricted, but im not 100% sure. I'm pretty sure the exhaust is a big bottleneck though. It must do wonders for the
fuel consumption too, i expect to use around 30% less now.
Anyway, thanks for the help, it gave me the confidence to do it myself. Hopefully my success will inspire someone else to try it:)
Now...where can i get a new exhaust...hmmm...
:)
-
i got it up to 60km/h easily
..that's awesome!!!
;D
..however, it wasn't too long ago that i got my butt kicked by a vitality 2t...
..and my a50 4t was running 80kmh then...
..might wanna investigate that cdi a bit...

Congrats, good to hear another winner.
