I haven't been able to find any info on derestricting the 2012 Kymco Agility 50 nor about the CDI. Does anyone know about this, as the 30 mph limit is killing me.
-
Your cdi wont be restricted only older ones are, the rest of the derestrict is the same as for older a50's. Fit a Smooth boss and an 82 main jet.
-
..i'm not sure if kymco is doing this to the a50s yet, but the driven pulleys can also be restricted...
..only way to rectify that is to replace them..
..top pic..unrestricted..
..bottom..restricted...
-
Another question, would I see any increase in performance from an open air filter compared to stock? If so, do you recommend any specific models?
-
Yes, performance will increase with th installation of a free-flow filter..
..however, you must increase your carb's main jet size when installing one, to keep your fuel mixture from becoming too lean..
..K&N filters are good, but there are several others out there as well..
..steer clear of the EMCO filters, as i know of 3 that have seperated from the mounting boot while going down th road... :o

Do you happen to know th diameter of the filter needed to fit he stock carb wordslinger?
I thought of doing mine last summer but didnt know if it was worth it?Take it top end is much the same but you maybe got a bit more power with the k&n? How much improvement is there, is it noticable?

..the K&N part # for the a50 filter is RC-2290...
..i think that a filter and appropriate jetting is the best performance mod you can do to these 4ts...
-
How would I go about increasing my jet size and ensuring I have the a50 engine?
Also, won't water get in the cold air filter when it rains?
-
...by "a50", i mean Agility 50..
..thre are many good vids on youtube on carb jet replacement, and other aspects of scoot tuning as well..
;D
peace
-
Is there no set jet size that people use with the K&N filter or would it be better buying a large carburetor with the K&N filter? There are some carburetors on Ebay for decent prices.
-
As a general rule an 88 or 90 main jet seems to work with an open filter but all scoots vary slightly and it also would depend on the rest of your set up.
Think i need to get a k&n soon and upjet. Prob do it once it warms up a bit outside.
-
What about just derestricting without any other mods? Would that damage my engine or any other component?
I'm currently looking at this one. http://www.ebay.com/itm/UNRESTRICTED-VARIATOR-DRIVE-BOSS-KYMCO-Agility-50-Vitality-50-Sento-50-/260881239776?pt=UK_Motorcycle_Parts&hash=item3cbdbbcee0#ht_2136wt_1180 (http://www.ebay.com/itm/UNRESTRICTED-VARIATOR-DRIVE-BOSS-KYMCO-Agility-50-Vitality-50-Sento-50-/260881239776?pt=UK_Motorcycle_Parts&hash=item3cbdbbcee0#ht_2136wt_1180)
Would it fit?
Also, what is a good rated online store to buy a jet kit from or other components? I'm located in the U.S.
-
Yup, that boss should be fine, i had one of those in mine for a while from the same seller.
-
..derestricting should not harm your engine..
..these scoots arent restricted to protect the engine, but to comply with local speed laws...
-
Heh, sorry for the constant flow of questions, but I have another.
I have a rattling noise coming from my belt drive cover, so I opened it and discovered the noise was coming from a washer that sits on the shaft of the electric starter and the case cover. It's quite annoying, so has anyone else had this problem and removed the washer without any problems?
-
You mean the small spindle thing for the electric start that sits just above the variator? Think its called a bendix. I dont have a washer on mine and never have had one? Maybe others on here can verify the same? If it had a washer on it i doubt it will sit in correctly? Cant think why a washer would be needed there?
-
Well I was assuming the washer was there to prevent direct contact of the bendix and casing when starting the scooter, so I left it on for safe measures. I'm planning on removing it today though, as the sound is really bothering me.
-
Maybe a bit has broken on yours then because my bendix is all one piece as far as i remember and wont come apart. Mine def has no washer on it at all tho because i had mine out last year and i kno it was one piece only. Have a look online for an Agility bendix and see if it looks like yours? Maybe even be a vid on youtube.
-
My 2011 AG has the same washer on and was making a noise so I covered it in grease and put it back in and the noise stopped.
-
Maybe they do have a washer then? Is it fixed onto the bedix itself or is it loose and comes off? I def didnt see any washer on mine but then again i wasnt looking for one.
-
..all the ones i've seen...many...have a thin thrust washer built onto the end of the bendix..
..i have seen one fall off, but that bendix was pretty worn...
-
I took mine off, but the noise still hasn't stopped. Oh well...
-
Guys I'm trying to work out if my 2010 Agility is faulty or normal.
My acceleration (#82 jet, smooth boss, no other changes) feel p*ss poor. I make 0-30 on my speedo about 15 seconds. I am always the slowest of all the other scooters (london - mainly vespas or similar) off of the lights and never really seem to catch up.
Is that normal? Or has everyone else got 125cc bikes? I weight about 97kg if that might be making a difference.
Any ideas? Is the Agility 50 generally quite slow, or does my bike have a problem?
Any thoughts welcome.
-

Guess mine prob does have one then? I thought you meant a loose washer like a normal washer/spacer, if its part of the bendix and dont cpke off i prob just never noticed it.
If you still have rattling check your rollers are ok and the plastic guides on the ramp plate arent broke on the variator.
-
Matty, im about 70kg and im not too bad, i can beat cars away from lights (slow cars ;D ) but its not great, its a 4t after all so slower than 2t scoots. Never timed my 0-30 so no idea if youre slow or not there.
-

The little devils are loose and tend to fall out as you remove the variator cover nearly forgot to put it back in the first time I took the cover off ::)

..could it be that your scoot is still restricted?
???

I have a rattling noise coming from my belt drive cover
..its not uncommon to hear "rattling", especially at idle...
..both my a50 engines rattled at the case..
;D
-
Well I ordered a smooth boss, I just hope there isn't another restriction.
-

I'll check mine next time im in there then. Guessin it maybe went for a walk the 1st time i ever opened it maybe unless it is still on there? Works fine anyway, or seems to, and doesnt rattle. Used to hear the rollers in the variator at times when reving on the stand but not really loud or so i would really notice it much. If theres no other problem its prob just normal noise.
Matty, Why not fit lighter rollers? 5.5g work out well for me.
-
Thanks Streido and others, and sorry for sort of hijacking the thread.
I did fit 5.5g rollers a while ago but the thing just revved super high really early and performance was poor.
I was having all sorts of other problems back then so maybe I'll try again to see if there's any improvement.
Don't think it's still restricted - the boss and the #82 jet are defo there. The CDI is original I think, and I can't see any obvious cutting, but then I'm told the 2010 agility doesn't have a restrictec cdi, but some disagree.
I'd really prefer to have a restricted bike but the last owner derestricted and didn't tell me. Just trying to get a feel for if the bike is naturally quite slow or not.
Thanks

I tried 5.5g roller weights in mine and they did just the same ened up with 6g by mixing three 5.5 with 3 of my original 6g after Sterido gave me the tip ;D
Unrestricted you should see around 42mph CDi on mine is deffo de-restricted, AG50 is a nippy rather than fast bike but I find climate makes a big difference to performance. Cold or wet days and power is down slightly, last week especially the bike felt a bit sluggish at times.

Maybe they changed somthing in the engine or cvt set-up after 2010 because 5.5g rollers seem to work pretty good on all older models with the restricted cdi? I think i read wordslinger mention something about newer a50's being a little different/slower than older ones? But maybe im wrong. I have a race variator fitted too now but originally did the rollers only 1st. A race variator helped my acceleration too Matty so youmay want to look at that.
-
..all i know, is i'm struggling to get 53 outta my 09 engine...
..my 08 was way more responsive...of course i broke it in WOT from day one...
..dunno how the 09 piston was seated...
..initially i did run 5.5s, but after i learned more about cvt tuning, i ran 4.7 gram rollers in the 08 for a long time...
-
Maybe its got something to with the newer cdi's Wordslinger? Wonder if you tried different cdi's?
Could be there is still some restriction in the new ones maybe?
-
..i tried every bit from the 08, even the intake, carb..lol...
..dunno where the diff is, other than inside the engine...i'm thinking it's piston/cylinder..

If you can get 50 or better out of you scoot you are doing great. I only get that if I have wind to my back and pushing me.

Interesting jezyg. I do get about 41mpg top (on the speedo anyway). It's my acceleration that is a bit embarrassing. I'll try mixing the roller weights and see how I get on.

I did a totally unscientific test last night on my way home from work. When i pulled away at a set of lights i counted seconds in my head til i hit 30mph on the gauge, wasnt exact but seemed close to actual seconds. Did it maybe 4-5 times going home and it came out as roughly 7-8 seconds to get me from stopped to 30mph. So Matty if you say it takes you 13secs then that seems very slow? Ok, my seconds maybe were not accurate seconds but if anything i think i was counting a little too fast so around 7-8 secs would be pretty close i think. Rollers def help on acceleration, lighter rollers = faster acceleration.
-
thanks streido. there's definitely something up with my scoot.
Will try the mixed rollers and see how i get on.
Then I think it's either the garage or the bin.

Check your belt isnt worn and past its tollerence for replacing. And if its an older scoot or has a few miles on it maybe its time to renew the torque spring or fit in a 1000rpm torque spring instead of stock if youre replacing it anyway. Check the variator face isnt scored and worn away with grooves in it, if it is fit a new one in.
