:-\ Ok, so i need alot of help. my father inlaw an I have been workin on my 06' kymco people s 50 4t for 3 days. i want to get it to move up to 50MPH (all de-restricted). so far we took it apart an machined down the center piece in the variator (the metal cylender in the center) im not sure what its called, but it let the belt ride up farther to make me go 3-5MPH faster. so that was successful. now i looked on some forums an they said its good i did that. Next i bought a NCY CDI from scooter parts place.com. its a vento/gy6 racing NCY CDI. which i found on another forum to buy. i just plugged it in today an i herd a POP! an nothing but smoke come out the front of my scooter an a stink. needless to say im calling them tomorrow for return. or to see if i even got the right 1. so is there any tips anyone can give me on what we can do to make this go any faster? part numbers an references would be greatly appreciated. thank you so much for you time.

..hopefully, that was just the fuse that popped....but i bet it's not the right cdi for your scoot..
..that scoot, de-restricted should hit around 45-50 mph...
easy...
..it may be possible to de-restrict your oem cdi..
..can you post a pic of it, showing the wiring connector??
..and, Welcome to th' Forum!
peace
..oh, wait...itsa 4t...
-
yes ill post a pic, and its a 6pin but it only uses 4 pins. 4 pin only uses three an the 2 pin only uses 1. post the pic in a second. thanks for the welcome =)
-
Welcome to the forum, Hell of a way to start. I don't have your model but i suspect your cdi is ac fired and you orderd a dc one,not compatable. Hopefully nothing else has fried. You will have to verify and get the right one.
For more speed you will want to upjet,open the airbox and exhaust. Doing plug readings are the only way to know if you have got it right.
I have not worked on one of these so not sure what jets you will want to order, but the rest can be done on a budget. A 1\4 inch hole in the airbox will let some more air in and 3 or more in the exhaust will let more out(near the outlet) use self tapping screws so you can plug if you've gone to far,but you must upjet to make things right,most will run an 85# main jet but i don't know about yours for sure.
Give this a try and let us know how it works. Good or bad.

its a 6pin but it only uses 4 pins. 4 pin only uses three an the 2 pin only uses 1
..what r th' wire colors??
-
@wordslinger, i Email'd you the pictures because i could not upload them to the site for some reason
-
...cool...th forum pics must be less than 192kb in file size...
-
so yea its a KYMCO PEOPLE S50 4T i hurd theres alot of difference in the air flow adjustments in the 2T and the 4T where the 2T you can unplug the green or pink wire an it works and you can drill holes in the airjet and the exhaust. they said it normally wont do much for the 4T. my father inlaw is asking this.
-
yea i know it was smallest possible and they were JPEG so i dont know why they didnt take.
-
..the key to getting performance from a 4t is getting the initial rpms up, and maintaining them throughout the scoot's powerband.....lighter roller weights..stiffer clutch springs..
..increased air flow...
..i'll go check those pics...
-
ok so by doin what i already did with the variator, is that good or bad that we machined it down so the belt has more room to move. and what should i do exactly and what parts should i get for it. im really bummed out the CDI didnt work so i guess, find the right CDI, but the 150$ variator kit off line some where (if you clould look up a good 1 for me an send me the link to it) and drill holes in the filter and exhaust? for more air?
-
Yep more air in and more air out,same princable 4t or 2t. Word is pushing 60mph on his agility 50
-
If trying to save a few bucks check this out http://www.provoscooter.com/scooters/ruima-racing-variator-139qmb.html (http://www.provoscooter.com/scooters/ruima-racing-variator-139qmb.html) . I like the malossi best but with this kit you get the driveface also for dirt cheap.
-
:o holy christ, is it possible for me to get mine up to that?
i only weigh bout 150LBS soaking wet lol. god if i could get up to 60 id be set.
Where exactly would i drill these holes any pics of examples. i dont want to drill somwhere i shouldnt lol.
-
to be honest that looks like what i have right now. theres not alot of difference in mine an that one. my dad said that with the performance variator thats 150$ its deeper and the ramps are less cuved so the weights shoot up an take off quicker.
-
actually there is a little difference. i looked at the pics closer
-
..oem carb..101 jet..K&N filter..modified oem exhaust...
..ncy variator (Malossi be comin')..oem drive face.. 27 grams of rollers (4.5) ..from 28.2 grams..(4.7) ..729 belt..
..oem clutch (Dr Pulley be comin')..malossi white 1000 contra..leo vince red 1000 fly springs..oem torque driver..oem driven face..
..i'm getting awesome-quick take-off (not 2-stroke, but as close as i've ever been)...gots those rpms up!..initial belt tug is GONE..
..remains in the higher revs, accelerating VERY NICELY to 47mph indicated (43 gps)...
..rpms settle out there as speed gradually increases if on a flat and the wind is favorable.....
..hit a little decline while running at 47, and scoot kinda takes off up to 52 indicated (49 gps)..
..downhill??...i don't know, as i've not ever had a gps on my scoot with the speedo in these positions..
..but it sure feels fast...........
-
so i can put all that on my scoot an it will boogy? how much would all this run an where can i get it. and are you sure it will work for my scoot. id hate to go through what i did tonight with the CDI lol.. POOF!... as of right now. mine takes off nicely doin bout 25-30 in 8-10 seconds. then it eventually works up to about 32. if im goin down hill about 35. an thats all she'll do. when i do go down hill it slows me down. so i still got to de-restrict the CDI so it dont do that.
-
most of the things your sayin is semi japanese to me lol. im not really machanic literate. but would this work? http://www.scootertronics.com/povaky4tag.html (http://www.scootertronics.com/povaky4tag.html)

we like this one better http://www.provoscooter.com/scooters/malossi-multivar-variator-kymco-50cc.html (http://www.provoscooter.com/scooters/malossi-multivar-variator-kymco-50cc.html)
-
basically, what parts should i get for my scooter now, where do i get them from like the places you guys shop at. and with the holes in the filter, exhaust and jets? im not 100% what they are. im sorry if im coming on as dumb. :P my dad knows alot about small engines but the scooter is complicated. he understands some of what you guys are saying. but if you guys can direct me where to go, what to do, and what to buy. ill try everything out this weekend an try to buy as much as i can to get it to where you guys are saying i can let you know if it all works out. but i dont want to mess anything up. so i need like pin pointed guidence. but i appreciate you guys helping me, thank you.
-
yea that one looks more promising an cheaper lol. i think ill try to get that as soon as i get paid. any other for sure parts you can reccommend to me? links?
-
I don't have your model but the next biggest bang for the buck would be a k/n filter mesure your carb air intake and buy on line or sometimes local shops will have. Send me a pic of your pipe and i'll see if i could show you where to drill some holes,Near the outlet is best. You may still be able to derestrict the oem cdi, Not alot of us have or even seen the people 4t up close ;)
-
Good luck on getting to 50. I hope you don't use your scooter as a primary means of transportation. Modified that much it won't last very long.
-
I understand your point of view old guy,but these modern scoots have been restricted to meet local and federal laws to do no more than 35mph. By allowing the motor to breath and run properly can actually be a benifit to longevity and you will be less of a hazard to your self and others on the road.
These motors were desinged to run above the 35mph mark troublefree in the asian market. That said You do not want to run wot all the time and if 50 and above is a speed you need you should get a bigger bike.
-
Good luck on getting to 50. I hope you don't use your scooter as a primary means of transportation. Modified that much it won't last very long.
WHOA.. i just turned 20,000km on my lil zx..she runs better now than when she was new!!... i can get up to 53mph and i ride EVERYDAY..the ONLY ride i have.. no spare scoot, nothing...mine isnt modded like sum here...yet, but she gets up and gos real good..gotta travel 35miles to town..one way...sorry old guy but i have to disagree with you there
-
Good luck on getting to 50. I hope you don't use your scooter as a primary means of transportation. Modified that much it won't last very long.
..i've been running my '08 WOT, all around the 50 mph and above mark, for over 25,000kms...
..51,000kms total...
..it's all about how you keep your scoot maintained...
..running as i do, every day, one MUST perform routine maintenance WAY more frequently...
..and, of course, every build of scoot is not the same..what works for mine may not work for another...
peace
-
G'day JDizzle, welcome to the forum. I don't like the sound of the pop from under the front cover. I am curious, what did you machine off the variator sleeve? Was it the diameter or the length? May be a silly question, but I am just curious. Good luck, you will have lots of fun with your scoot, I have a selection of bikes to ride but still like the little scoot.
-
we machined the diameter so its al the way flush. we didnt shorten it at all, because then A it would wobble and B the weights would fly out lol.
-
well my dad looked at the wiring on the bikes an he said that if we would have switched the wiring and put them in a different order it might not have poped.. any of you guys know anything bout the wiring if you buy a new CDI.. COULD SOME ONE TELL ME WHERE TO BUY A CDI FOR MY SCOOT THAT WONT POP lol.
-
..you can get a oem cdi at stadiumyamaha.com...
...wiring schematics are posted in the "links to service manuals" thread in the "General" board...
-
i was looking for a performance CDI that will de-restrict it from slowing down going down hill and give it more RPM
-
@ ART and @ WORD. do you guys think this would be good to put on my scoot? http://www.provoscooter.com/stage-one-performance-kit-kymco-50-4t-gy6-qmb139.html (http://www.provoscooter.com/stage-one-performance-kit-kymco-50-4t-gy6-qmb139.html)
-
...well, it says that pipe is for a gy6 4t engine....
..not sure that's the one you want....
-
Thats the problem not to many people s50 owners not sure if the 2t is the same if it is get the cobra cdi,you could also derestrict the stock one if its like the agility 50. Maybe a pic would help.
-
Honestly I think you could mod the stock pipe the rest should be fine and alot cheaper!
-
"http://www.scootertronics.com/elovizxchyaz.html"
..maybe this one...but call them at the shop...
..they could point youto a good one, i'd bet...
-
Honestly I think you could mod the stock pipe the rest should be fine and alot cheaper!
..i agree!!
-
Here's a pic of a s200 im playing with,just a few holes to get some more flow,got to jet to match it.
-
..could you tell a difference in flow??
..with those holes??
-
it said it would work on the people s50 4t.. well you said to put holes in the filter and the exhaust. where exactly would i put these holes like, you can see the exhaust in my scooter picture. and how many holes should i do on both the exhaust an filter.
-
gotcha, thanks for the pic lol i was thinking in the BIG area lol. but i agree with word, did you notice a difference? and what about the air filter?
-
sorry wat do you mean by jet, i see u use that term alot.
-
you can see the exhaust in my scooter picture
..the profile pic??
..what kinda pipe is that??
..oem??
..it's so small, and my eyes are so old....
-
yeah its the stock pipe looks like the one ART just showed us.
@word and @art... such as the things that i have on my bike for messing with. is there anything i should take off thats not needed or is not important?
-
..the jet is the port in your carb, through which fuel is sucked up through, into the airstream from your carb's air intake...filter...
..any time you mod something that increases the flow of air into, or out of your engine, you MUST increase the diameter of this port..(jet)...
-
do u buy a bigger jet or can u mod it yourself?
-
Yes word the holes were quite noticable and a little meaner too ;)
On the people 50 4t i haven't seen one up close but if like the others try takeng the cover of the air filter and a few holes neer the outlet of the exhaust try "3" 1/4" holes to start with. You can fill them back in with self tapping screws if you go too far. Of corse you need to up jet to take advantage of the better flow and don't want to run your scoot too lean it will damage your engine.
It's trial and error but just takeing the cover off will give you an idea of how restricted it is than you have to match the out going with the in coming. You will notice an instant difference but will have to play with it a bit to get all working together(more air=Need more fuel)
-
my dad said me an him are going to focus on the CDI and finishing the variator for now. so i need a link for a performance de-restricted cdi for my scoot and we will make the variator diameter one size instead of it having that lip on it to restrict it. do you guys know where i can find a de-restricted/performance cdi? for my scoot?
-
..most of us drill our own...and if we need to down-size, we heat them on a burner, apply some solder into the port, and then re-drill them smaller...
-
..dang..i keep forgettin' itsa 4t......
-
so what would that mean?
-
A pic of your cdi would help you may be able to mod it. I have never seen one for that model
-
i cant get them on here but if u give me a Email i can send them to, i can have u 3 pics in 5 mins. or a phone number i can text the pics to.
-
Most of us have the 2t model some parts interchange just don't know about yours for sure ;)
-
dhughes36@northstate.net
-
i sent them to you when i first logged on the forum word, remember?
-
..kk..lemme look...
:o
-
..my pipes..
-
Click on my name for my info there's a hotmail account set up there
-
i sent you 2 more pix word the last one is coming now its a better well lit pic
-
...did you try cutting a notch in the edge of your cdi??
..looks like what it will need...
-
art your email is hidden
-
we started digging into the bottom of it but we dont know how far to go or what to do wen we see anything. looking for a green wire??
-
Hmm O.k.
-
...this pic shows how far you can go without even harming a thing...
..your wires are similar in color to mine, but seem to be in a different orientation...
-
..you may never see the wire...it's tiny and sometimes the "plastic" drags over the copper conductor, hiding it...
..but it will be in the corner, like where is all shaved off in that pic...
-
My 2009 people 2t could not be de restricted this way all others older than 2008 could that I know of. I had to get the cobra cdi to derestrict it.
-
..if you cut a notch in that edge, at least 1/4 inch deep, you WILL cut the wire, if it's indeed there..
..we're speculating at this point, but you MOST LIKELY will damage NOTHING by trying it..
-
were close. theres a couple post there. so if the wire is between the post we got it. my dads trying it now.
-
..yeah, art...none of really know about the ppl 4t so much....
..not many ppl ride them i reckon...
-
were close. theres a couple post there. so if the wire is between the post we got it. my dads trying it now.
..all that unit is, is a circuit board with various components, encased in plastic and epoxy...
-
Ya can't give a whole lot of specific info cause I don't know for sure.
-
word. im emailing you the pic of my cdi with the notch right now to see if i should go deeper or just cut more
-
Ya can't give a whole lot of specific info cause I don't know for sure.
..yup...right now, it's just educated guesses...
-
...you gotta cut the corner!!
-
like the actual corner or the corner of the middle?
-
...where you've dug in...in that pic...cut to the right, and down, 1/4"
-
Ha! post a pic when done,i'm in the dark :'( ;D :D ;)
-
he asked what is he looking for or will we hit it without seeing it?
-
art look in ur email in 2 mins i see ur email now im sending you the pic
-
..see??!!
-
...just cut!!!...lol..
-
ok we see a black shiny wire...........wat do we do??
-
...the wire, if present, is right in that corner, to the right of the hole you've dug into the epoxy...
-
..CUT IT AND PRAY FOR RPMS!!!
;D
-
which way is right? with the green plug up wards or down wards?
-
..away from the green...down...to the right, in the pic....
-
...clip the corner..the edge..the right angle...go through it!!
-
im sending you one more pic right now it shows the progress an u tell me left or right of that.
-
there is a small silver wire in the dead center poking out also.
-
Ha! the suspence is killing me ::) If it don't work I think the cobra will work for ya. Looks like the 2t one.
-
..like this....
-
..close-up...
-
ok we cut it an i took it for a night spin.. god its cold out.. the highest i got was 35 but it took a long straight away to get to it.. so i dont think it did much justice :(
-
...dang....
-
ok we cut it an i took it for a night spin.. god its cold out..
..where ya'll located??
-
i thank you guys for you input. OH. when my scoot is up on its park stand it revs alot louder. but did nothing for speed. im in GLENBURNIE MD
-
...then, i'd bet there is something else keeping your speed restricted, other than the cdi...
..wow..it's like still 80 degrees here....
-
we gotta go to bed but do u have any guesses on what it could be restricting my speed?? and its like 65 outside right now plus i was riding my scoot with a tanktop on an shorts.. pretty nippy.
-
...it would be awesome, of you could measure your variator drive boss...
..both in diameter, and length...
..i have the de-restricted specs of a boss somewhere aroundhere...
..post a pic of your cdi cut!!!!
..keep in mind, we're all hitting un-travelled territories with this ppl 4t...
..but i'm pretty sure we can all get it figured out..
..think of how much you've learned already!!..the fun has just begun!!!
peace
-
..yeah, i can stand tank-tops til about 70....
;D
-
My 2009 people 2t was pipe jetting mostly but cdi had to be derestricted to get to that part first(the boss had been changed at the shop before i bought it). For a 2t it was slow!!! I owned 2 older ones that would leave it in the dust till i modded it. 35 mph was tops down hill. Was doing 55mph + with me 220lbs when i sold it.
I put one 3/8 hole in the air box an #85 main jet and swaped the pipe with a leftover 2002 people 50 I had laying around and that was it.(Plus the kymco cobra cdi)
-
That could be the key,the boss may not be as long as the older ones or replacments. Get a mesurement I got a couple laying around here somewhere I'll let one go for 20 percent of new plus shipping ;)
-
...there are different drive boss lengths...just shorter by a few millimeters, but that makes a big difference...
-
Ya i'll have to match mine up and take a closer look. They seem to all be the same but havn't looked that close,but was thinking about the restricted ones,may not be the same at all,never had one.
-
A copy of the email for J. The transmition,veriater and clutch. I think it stands for constant variable transmision. But ya new variater the right weights and probably the white contra spring for the clutch should get you a bit more. Kinda trial and error
