How do you cut the cdi like which part and which jet should I use in the carb
Thanks :)
-
If you look here, on the 2nd page, wordslinger has posted a photo of a cut cdi, I didnt actually cut it I used a large flat file, http://www.kymcoforum.com/index.php?topic=1728.15 (http://www.kymcoforum.com/index.php?topic=1728.15)
I followed his advice and mine is fine. I was worried cos I was cutting deeper and deeper into the cdi and saw no wire, was about to stop and give up just when I had one last file and found the thin wire. Cut it and I now have no rev limit, woohoo. I cut into the cdi 1st but had no luck so resorted to the file which was much better.
I have read that you must also change the variator boss to a flat unrestricted one or you may over rev the engine due to the restriction there. I cut mine and rode like that for 2-3 weeks till I got my smooth boss.
Also you will need an #82 main jet after doing the boss.

Hope that helps.

Thanks and can you send me a link for what I need like the variator and carb? And do you keep fileling until you hit a wire then cut the wire
Also can I use it without the variator thing
Thanks :)
-
I just cut the CDI wire on my 2006 Agility 50 two hours ago. 15 seconds with a hacksaw and it was done. I had to dig into the cut a bit to see that I actually cut a wire. Picked up about 6-7 MPH on a straight, flat street. Now does 40 MPH with no other modifications.
-
@dale, thats a good gain, I think I only got 4-5 mph at most from my cdi cut.
@ charlie, Will try find links for your boss and post them. I got my bits from Taipai Scooter Assassins, you need an unrestricted boss and an 82 main jet for the carb. Your engine is a gy6 139qmb for the agility 4t 50cc.
-
Oh, and you probably will want lighter rollers, stock weight is 6.5g, i use 5.5g. The weights are size 16x13, plus your roller weight, ie 16x13, 5.5g rollers. You may as well do them when you have the variator off to do the boss. If your doing it yourself you will probably need an impact wrench to remove the variator nut too.
You may want to look at fitting a race variator too, gives faster, smoother acceleration and higher max speed too. Race variator gave me 5-8mph more after I did my derestrict. Now I get 45-48mph on flats and 50 or just over down hills. Again I got mine from Taipai Scooter Assassins.
-
Thanks guys all done great help
-
No probs, glad your sorted. You can soon have some fun riding your scoot instead of being overtaken by cyclists ;D
-
Yeah thanks and another question how do I change the variator and which sizes do I use and do you think you can send me a link on which parts I need
-
Why dont you just give me your address and i'll come fit it for you too? ;D LOL
Will have a look and see later if I can find the links, just about to have dinner.
You should search on youtube for "how a variator works" theres a good vid to explain it if your not sure yet. if you look for "gy6 variator" or "gy6 variator removal" and you will see there how to remove it, pretty easy if you have an impact wrench, a nightmare if you dont, imo.
You will find a vid on how to change the main jet too under "gy6 main jet" surprisingly enough ;D
You will need an #82 main jet. If I see links later tonight I will post them for you.
As long as you are ok working on basic mechanics and can use tools etc you should be ok to change it, if your not happy doing it then better to get someone to help out or do it for you tho.
-
Yeah thanks cheers mate
-
Ok, so these are the parts I put on my scoot to derestrict it after I cut my cdi,
Boss - http://www.exportstrength.com/product_info.php?cPath=22_44_332&products_id=403 (http://www.exportstrength.com/product_info.php?cPath=22_44_332&products_id=403)
Rollers - http://cgi.ebay.co.uk/Variator-Rollers-16x13-5-5g-Speedfight-Vivacity-Trekker-/270713882746?pt=UK_Motorcycle_Parts&hash=item3f07ce087a#ht_15006wt_1046 (http://cgi.ebay.co.uk/Variator-Rollers-16x13-5-5g-Speedfight-Vivacity-Trekker-/270713882746?pt=UK_Motorcycle_Parts&hash=item3f07ce087a#ht_15006wt_1046)
main jet - #82 ( not sure what mm it is, I just took my old stock #80 main jet out and drove over to my kymco dealer to get one and compared the thread on it to mine) email taipei scooter assassins or any ebay seller to check it fits.
The above gave me better acceleration and top speed of about 43 I think.
Next i fitted this race variator but you may not want to bother with this right now, up to you. Or you can get many other makes at different prices, malossi etc. This is mine anyway, gave smoother and quicker acceleration and some more top speed too.
http://cgi.ebay.co.uk/RACE-VARIATOR-GY6-50-KYMCO-BAOTIAN-LIFAN-Chinese-/300540989339?pt=UK_Motorcycle_Parts&hash=item45f9a38f9b#ht_1861wt_685 (http://cgi.ebay.co.uk/RACE-VARIATOR-GY6-50-KYMCO-BAOTIAN-LIFAN-Chinese-/300540989339?pt=UK_Motorcycle_Parts&hash=item45f9a38f9b#ht_1861wt_685)
After this I now get about 48mph on the flat (on the clock, prob 43mph actual since speedos are generous). Changing my torque spring in the clutch at the weekend to a 1000rpm to improve my uphill speed a bit too. Maybe think about that after you derestrict it, see how you feel once you try it, you may not need it.
You can get the same bits elsewhere too but if you use Taipai S A then remember the delivery can be slow, usually 1-2 weeks to the UK.
Get tuning and good luck! If you get no luck on main jet size post a new thread to ask the mm diameter and someone should tell you.
-
Let us know how that torque spring works out.
-
Will do Encya, if it ever arrives from taipai, been waiting 2 wks so far. Just about to finish work for the day so im hoping the spring has been delivered today and is at home waiting for me, been saying that every day this week tho. Let you know how it does once I try ordered the 3 spring set so I can try 1000, 1500, or 2000rpm spring. Everyone seems to favor the 1000rpm spring from reading up on this forum tho, so going to try that 1st.
-
Taipei has an 88 main jet for the agility on their site so i would imagine they can get any size here's the link http://www.exportstrength.com/index.php?cPath=22_45_905 (http://www.exportstrength.com/index.php?cPath=22_45_905) it also has measurements in the picture 4.85mm thread diameter
-
Saw the 88 jet H.R, was surprised they dont have others listed under agility section.
I initially ordered an 82 jet from Taipai S.A but when it arrived the thread was too small so it never fit. I had my carb in bits and didnt want to put it back just to need to strip it again, so I took out my old 80 jet, went to the Kymco dealer and got the right one there. Just wanted to double check he gets the right size cos one they sent me was wrong, and kymco dealer also gave me wrong one at 1st. If I hadnt taken my 80 jet to compare thread size then I would now have 2 main jets I couldnt use. Dont know if some carbs are different or not, or if Taipai and my Kymco dealer are just crap and dont know the correct size.
Home from work now and still no torque spring delivered yet, not a happy bunny, 2 wks now im waiting. Better come tomorrow.
-
Steido, I realise the agility and ZX are worlds apart, but I find the 1,000 torque spring and 2,000 fly springs are a good combination.
2 week waits are the norm, I am waitng 3 weeks now for an item from America.
Last night I ordered a Cobra tacho for my and a lightbar set for my Boulevard from two different sellers in America. See how long they take, not too long I hope.:)
-
Yeah sid most of the other agility riders sems to say they go with 1000 torque and 1500 fly springs. Was going to order just the 1000 spring but it came in the pack of 3 differnt one in it so ive got the option now to try them all and jiggle it till im happy - if they ever arrive!
Not ordered any fly springs yet, get them next months pay hopefully and prob buy the set so I can try different combos.
Soon as they invent a teleport machine to get instant delivery we'll be happy ;D
-
Yeah, that is the best way to go, I bought one set of fly springs, then bought another, patience helps.
-
i ran into the same problem myself with the dealership jets streido they actually had to order it from kymco & could only get either the 80 or 82, i gave up and used a torch tip cleaning set to file out my 80 jet i took off when i de-restricted the scoot. i'm playing the waiting game as well on my naraku high speed variator & 1000 rpm contra, though my seller got my rebuild kit to me in 4 days! with free shipping i might add! i've got a set of 2000 fly springs already so i'll try them out once i get my other transmission goodies :D i'm pretty darn close to being able to ride one of those pull up on the handlebar wheelies with my stock tranny even with 8 gram rollers so i may actually be able to do it with these parts ;D guess we'll see... 5 days wait so far...
-
wow.. it's here! gonna go try the variator on
-
Wheelies? I dream of wheelies ;D
Guess the change of fly springs makes a big difference to take off then? I think ill try the 1500 fly springs with the 1000 torque 1st,want to ride on 7.5g rollers or even heavier maybe to get few mph extra top end. Im hoping i can try different combos on the rear end till it pulls well uphill, has good acceleration all round and still gets around 50-52mph top speed, maybe impossible but im going to try anyway.
Was getting 50-52 on my 7.5g rollers before but uphil and pulling away was affected so i went back to 5.5g till my spring set arrives.
I guess if you put in the 1500 or 2000 torque spring you can run even heavier roller weights without losing acceleration?
-
hope you enjoy the variator, i saw great improvement when i fitted mine and that was just a gy6 clone, the brand name you got maybe even better.
-
Can anybody send me links of what I need like clutch variator. Rollers etc
-
I put links for everything you need to derestrict on page 1, rollers, boss etc.
You dont need to touch the clutch to derestrict it. I would derestrict 1st then later on you can upgrade or tune you clutch if you want to. Better to get the derestrict done 1st so you can see how you feel it is, you may be happy with it and not need to doing anything on the clutch side. Im only doing mine cos I want more acceleration and uphill speed now.
You will find a huge difference in performance after the derestrict and may be happy to leave it like that.
-
Ok mate cheers
-
streido's right the derestrict made my scoot feel like a completely different animal but i've got a big bore kit installed now which is why i'm tuning my clutch/other transmission parts. gotta have high quality parts to put my 4 or so horsepower :D to that back wheel! haha you should be at least slightly amazed by the difference after the derestrict
-
If I change the variator will I need a new belt ?? If so whatbsize and can you send a link ? Cheers
-
No, you wont need a new belt, mine is still running the stock belt.
-
@Encya the new 1000rpm worked out well with 5,5g rollers. I recommend it, made a difference to my agility. More torquey, better uphills, better take off when still moving after slowing down. Tried 7.5g rollers but they were too heavy so using 5.5g and that works not too bad.
-
Great. I'm thinking of ordering some 5.5g & 6g rollers to experiment with, along with a race variator and the torque springs as well. Because I only weigh about 155 lbs. my optimum setup may vary slightly from yours. But it seems like you're in the ball park of where I wanna be. I would like to use Dr Pulley Sliders rather than the rollers. I doesn't seem like may guys on here are using the sliders though?
-
I want to switch to the sliders too but have been waiting till I have it set up just right so I can order the weight im happy with.
Once I do my fly springs I may well order 5.5g sliders, think I want to try 5g or 4.5g rollers 1st tho maybe. When I find what weight works best with my final set up then I will def get some sliders.
I gained probably 5-8mph top end after I fitted my race variator, but he acceleration is a lot smoother and is faster too. I did have a notable flat spot around 30mph on the stock variator. I had very slight flat spot after fitting the race variator and now with the 1000rpm torque spring in I have no flat spots at all, it just pulls all the way to top speed. 5-8mph faster uphill too now with new spring in.
-
Buy various sets of cheap rollers first to work out what weight you want, remembering that cheap ones do wear out quicker. No point wasting money, once you have your setup worked out, then buy the sliders. I am using Dr. Pulley sliders and do like them. I have heard that when using Dr. Pulley sliders, to use 1/2-1 gram heavier that you would with rollers, though I don't know if there is anything in that.
-
Thanks for that sid, will keep it in mind when i so get round to ordering some.

Thanks sloth, testing rollers then going to sliders was what I originally planned on doing, but was concerned with what you mentioned about possibly having to go heavier when going to sliders. So I may just get 5.5g & 6g sliders, as I'm pretty sure from what I've read on here, that one or the other will work pretty well for me.
About the variator? Does Dr Pulley sell one for our AG 50's?
-
What and where do the torque springs go and what do they improve and what are they for ?
-
The torque spring sits behind the clutch and controls when the belt moves up and down the rear pulley. The rear pulley is kind of like a rear gear on a pedal bike.
It improves uphill speed and gives you a more torquey feel to it, get u back up to speed quicker, especially after slowing down for traffic or bends.
Think standard is about 850rpm, most agility 50 users seem to favor changing it and using a 1000rpm spring. Thats what I did on my scooter last weekend, and it feels much nicer to ride now.
Like I said before tho, best to just de-restrict 1st and see how you feel then. You might not want to do any more than a derestrict.
-
i think i may be going with a 1500 torque spring next i want to run heavier weights for staying power at higher speed but it still won't keep my revs high enough with the 8 gram weights for now though i think i'm going to try my 5.8s for a few days
