Agility 50 / Re: Kymco agility 50 4t slow !!
« on: March 21, 2018, 09:31:27 PM »
Hi! sorry for the late reply, yes unrestricting the boss will help you a ton! my managed to go from 28 mph to 40 mph after changing the boss its honestly a huge difference in top speed. If you put a derestricted cdi in it you need a 82 main jet because it will run at higher revs. i managed to get 57 mph out of mine today down a really on hill. Changing the torque spring from the stock one to 1500rpm was my favourite mod. so if you want to get the most out of your scooter and be able to cruise at 40-45 on flat roads and 50 downhills then do this.
-CDI Unrestricted
-Boss
-Main jet 82
-Clutch Torque spring 1500
- i changed my rollers to 5.5g but you dont need to do that
then you'll be a happy rider! :) good luck

Why? I swapped the main jet to 82, better coil, cdi and now i cruise at around 43 mph and downhill i get 48 i haven't pushed it further but i might get 50 if it's long enough, dont underestimate the power of the KKYMMCOOO

Im prety sure most will work as long as the size is 20mmx38mm however i wouldnt take a risk if i were you, i just bought one that said it is specifically for my scooter.
This is the one i bought and it fit mine fine : http://www.ebay.co.uk/itm/UNRESTRICTED-VARIATOR-DRIVE-BOSS-BUSH-for-KYMCO-Vitality-50-Activ-50cc-/301467129162

Good luck!

Sure, ill send you a youtube video on how to do the variator boss which will give you a really good increase in top speed! Its very simple, you just unscrew all the bolts around the black case below the air box, then you need either an electric impact gun or a variator holder tool, unscrew the cog looking like thing on the left, on your right is your clutch but you dont need to touch that, once you take the variator off you slide the belt off the metal boss ( the round looking like pipe), you pull it out with the variator and pop the new smooth boss in and re fit everything in reverse order, if that isn't good enough then here is a youtube video of how to do it mate!

Good luck!

So! After 2 hours of riding, ive realised that the scooter started feeling worse before because the rollers were worn! and now with the 82 main jet and new rollers its very very nice and doesnt struggle to keep up with traffic! very good, it tops out at 40 but thats because it needs a new belt! So my final review is, getting clutch springs- 1000rpm or 1500rpm i chose 1500rpm but 1000rpm is better choice for in town riding, do the 82 main jet but clean the carb out at the same time, put 5.5 gram naraku rollers in it that is a very nice improvement, and you dont need to upgrade the ignition coil but i did just for the sake of it! All the links of purchases below:
Ignition coil : https://www.ebay.co.uk/itm/Racing-DC-CDI-Ignition-Coil-For-Scooter-GY6-50cc-125cc-150cc-Kymco-SYM-Vento/121936214118?ssPageName=STRK%3AMEBIDX%3AIT&_trksid=p2060353.m1438.l2649

82 Main jet for stock carb : https://www.ebay.co.uk/itm/Keihin-Carburettor-Carb-M5-Main-Jet/272844414070?ssPageName=STRK%3AMEBIDX%3AIT&var=572022211238&_trksid=p2060353.m1438.l2649

5.5 gram quality rollers from naraku : https://www.ebay.co.uk/itm/GY6-139QMA-QMB-50cc-5-5-gram-HD-Variator-Rollers/272805158698?ssPageName=STRK%3AMEBIDX%3AIT&_trksid=p2060353.m1438.l2649

I have yet tried to put a new 1500 rpm contra spring in it so not going to recommend it yet, but once i do ill tell you if its worth it, i have a suspision that mine already has a 1500rpm spring but here is the link : https://www.ebay.co.uk/itm/Kymco-Agility-50-1500-rpm-Sport-Clutch-Contra-Spring/302289885501?ssPageName=STRK%3AMEBIDX%3AIT&_trksid=p2057872.m2749.l2649

Holy crap! putting 5.5 gram rollers made a big difference for me, mainly because the old ones had flat spots and were very dirty, when you change the variator make sure to clean it very very well with some cloth and do not, i repeat do not put lube inside it will not work well at all, they need to ROLL hence the name. I didnt do the contra spring as i didnt have the right tools! I put the new ignition coil in and that made it start so well in dry and wet weather!

Personally, im not going to cut my cdi as i dont trust that method, If i were you i would just leave the cdi stock without cutting it, I'm fitting the contra spring and new rollers today and tell you if its worth it! So far i put bigger main jet and unrestricted boss, the boss increased the top speed by about 8 mph, the jet however i put an 82 in and it decreased the performance, so the boss is a must and ill tell you about rollers weights and contra spring once fitted! I'm making this as honest as possible

Okay, ive now noticed that the bike is starting to run worse and worse and its quite a lot slower, im not sure what it might be but i might put the 80 main jet back in it and see if that will fix it, i reckon its getting too much fuel now! Im going to try fit some parts tomorrow to it if the weather isn't shiet like it is now!

Yes, today on my daily ride there was quite a big difference which i didn't feel before maybe because i was really looking hard, it was pulling up slight hills quite a lot better but up big hills around 23mph, however, the new contra spring will hopefully make a difference as i read other people say, im pretty busy right now as i have exams, im gonna try fit it on the weekend. 82 main jet for me personally is a definate, this also in my opinion makes it run smoother!

I fitted the 82 main jet. and it  didnt feel like it made any difference, but i noticed on the slight hill i usually do 30 i was doing 34 and there is slight improvemnts overall but its not very noticable, next is contra spring and rollers, should be able to fit them tomorrow or the day after that!

Okay, so after fitting the iridium spark plug, the only difference is that it runs a bit smoother and starts much easier when cold and very slightly better on hills but not even noticable! I'm waiting for my impact gun to arrive now as i cant get the clutch and variator off, it should arrive in a week or so and ill tell you how it goes!

Right so most of the parts have arrived. I now have the contra spring, rollers, spark plug, main jet. i will be installing them one by one to see which one gives the biggest boost. tomorrow im going to install the spark plug see if that helps it at all, then maybe the bigger main jet althought im not very experienced with carbs, but its always good to learn!!. and then later in the week ill install the rest im waiting for my impact gun to arrive!

You really know way less than you think... My agility I put a smooth boss in it and that's it and now it does 38mph on flat... I ordered more parts and should do about 45 on flat. stop trying to be a smartass and pretending that you know everything because you clearly don't. If you think an a50 de-restricted won't do 45 flat then you really must have a sh** agility if you even have one. stop complaining and saying bullsh** and move on.
