Scooters - 50cc => Agility 50 => Topic started by: adamsd11 on June 26, 2011, 04:50:03 PM

I brought a Agility 50 as a spares repair for £25. After a new frame and 4 hours worth of work we had it running road legal. Ever since, the scooter max's out at about 25mph. The scooter seems sluggish and lacks power when setting off. I am going to put a new Spark plug in it and see if this cures the problem? Any other advice? Im thinking about eventually upgrading it to 80cc but im not sure wether its worth it. Any other mods i can do appart from the CDI unit? Also are the Leo Vince exhausts worth buying?
Cheers, Adam

Welcome aboard, a smooth variator boss and an #82 main jet will get yoy derestricted after you cut the cdi wire. That should get you up to around 42-43 mph showing on the speedo.
Lighter rollers in the variator, 5.5g work well, to help acceleration.
These simple and cheap mods should get you started. Theres loads more you can do, but thats the basics to so 1st then you can build on it from there.
Good job getting it fixed up.
-
ahh thanks mate. Have you got links to any website you can get the parts from? Like the rollers? Cheers
-
You can get rollers from any scooter/bike shop or online store or i usually just get mine off ebay.
Your stock rollers are 6.5g so going a size lighter helps the acceleration a bit. Some folk even use 4.5g,i havent tried any 4.5g so cant say how they would work,i use 5.5g myself just now but im in the middle of new mods right now so hope to go up to 7.5g soon.
If your looking for 5.5g's just buy any sized 16x13 5.5g rollers and they will fit, or 16x13 + what weight you want.
You can get a smooth boss lots of places,you want a smooth variator boss for a 50cc 4t 139qmb GY6 engine. Here a link to the one i got 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)
I used this for a while then fitted a race variator and used my old stock boss that i got lathed smooth cos i just felt i fit better, maybe just my imagination but it just feels better to me. If you can get someone to lathe your smooth just do that instead? or get a machine shop to smooth it out its not a big job so should be cheap.
This is the variator i fitted too if you want to look at changing that while your in there 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)
Gives smoother quicker acceleration and a little bit top end. You can get brandname ones too,Malossi,NYC etc, up to you how much you want to pay really?
and any bike scooter shop should sell #82 main jets too.
Keep us posted how you get on ;D
-
So the lighter rollers the faster acceleration? and the heavier the rollers the better top spead?
I was on it last night and got the bike up to 38mph on the speado but then i had to brake into a corner. The only thing i have done on the bike is the Cut on the CDI Unit?
Whats the best youve got out of yours, with the mods on it and what mods have you got. The variator looks good and will probs get that. still like the sound of 80cc kit aswell? Cheers
-
I was about to install an 80cc kit on mine but when I looked into it realized they is the tendency for a lot of issues when it comes to tuning and durability of the motor.
I went with a 70cc airsal kit instead, decent quality and not as much stress on the cylinder and crankshaft and bearings.
-
38mph just from the cdi cut is very good, think I only got to about 33-34 max when I did mine.
Yeah, in general,
Lighter rollers = better acceleration, slight loss of top end speed.
Heavier rollers = slower acceleration, slight gain in top speed.
I fitted 5.5g rollers, cut cdi, smoothed boss, race variator, #82 main jet, iridium spark plug and got about 45-48mph showing on the speedo generally driving on the flats, now and again it goes just over the 50mph marker down hills.
Since then I fitted a 1000rpm torque spring and this helps goin uphill, gave me an extra 5-8mph up hills compared with stock torque spring. Keeps you in a lower gearing longer and you feel more torque in the engine. Also going to swap my fly springs in the clutch for 1500rpm springs, that gives better off the line speed by letting the engine rev higher before the clutch grabs. Just waiting for them coming feom taipai.
I still have my stock exhaust and airbox right now too, plan to upgrade these one I get the cash tho, just cos I prefer the look, I may gain a couple of mph top end too tho if im lucky.
I would do the boss and main jet 1st and see how you feel with that. If you want to you can then fit a race variator and move onto the torque spring and clutch spring later if you want to go that far. I dont plan on changing my cc, on mine, prob just go for a bigger bike next year or 2.

Welcome to the forum, streido has just gone through some performance enhancing mods for a cost effective price so if you read through his posts you will be on the right track. Wordslinger is a member who is m.i.a., was rather experimentative,(did I just make a new word?) also has a wealth of info in his posts.
-
Another option repsol, trade it in on a 2 stroke. ;)
Just joshin.
-
Thanks for all your help so far guys! My dads got the bug now and we have just brought a 2nd Agility 50! I must say the leovince exhaust seems worth buying! It makes the bike sound so much better and performance! i will upload pictures soon!
-
Hi again guys, going to pick up my 3rd tomorrow. Officially got the bug. The first Kymco that was hesitant had blown gaskets so the oil was leaking. That is going to be fixed within the next month. :)

www.tntcycles-atv.com (http://www.tntcycles-atv.com) i can get oem or aftermarket parts ... let me know what you are looking for
or call Jenny 717-453-7265 or 717-602-5901
-
Does "Jenny" ever write anything else apart from her sales pitch here? Its becoming boring now. Why not offer the guy a decent discount or just stop trying to push your business here, we can get all the parts you offer cheaper elsewhere online.
-
"Jenny" is probably ordering from kymcopartsonline.com and looking for suckers to bite...
One thing I've noticed about the scooter biz at least in the states is there are a lot of people out there willing to take advantage of the lack of knowledge of most people thaat buy/own scooters. they got me when I first got mine, a couple times.....

Ive brought new rollers, cut the CDI and cut the variator. My ped now hits 49mph but no matter what hill it will not hit 50!
Im looking at more mods like, race clutches, race carbs, k&n air filters. Will this change anything? im 16 and all my mates have 2 stroke hairdryers (Airox's, speedfights, nrg's, sr50's) and i want to prove that a kymco can hit around 60mph. Im from the uk so i need uk sites...
any ideas how to get an extra 10mph?

What weight rollers? By cut the variator, I assume you mean the variator boss? What length was it cut to?
-
72cc kit and some transmission tweaking got me there along with air filter, bigger main jet, rollers etc.
-
im not sure what size and yeah it was the boss, my dad cut it and its the same size as they all show on the youtube videos? i used one of them to do it. and i have 2 kymcos with the 80cc's but it doesnt seem to make a difference. I was thinking maybe K&N Filter? Bigger Main Jet? New race clutch and carb?
Any other recomendations?
-
If you're running an 80cc kit without a free flow air filter and a larger main jet you won't see much difference and are probably doing severe damage to your scooter.
Getting a performance variator is one of the biggest and most beneficial (as far as performance goes) mods you can do.
-
dont forget to have a nice set of tyres on, these scoots love the corners, i can flick through corners at 47-50ish...great fun :)
-
Yeah my peds just have redone their M.O.T's so they all have good tyres atm.
What do you suggest to run the 80cc bikes? air flter, main jet wise?
im going to look into getting a full race variator as ive seen them and they look like they could do alot :D
-
the parts i have fitted to mine at the minute are a Naraku Race Variator (with 1000rpm torque spring) and a Naraku Race Cdi. can hit around 47 to 50 on a good day and in england not many of em come about lol.
-
You really must have a bigger jet, if your saying you still have the stock #80 jet installed. For a derestricted scooter it should be #82, if you then fit a open air filter then usually its a #88 or #90 jet.
A race variator is a must, imo, better acceleration, much smoother ride and few mph top end gained usually. I got 3-4mph and ijust use a cheapo chinese clone race variator from Taipai scooter assassins. Im also in the uk, so the only downside to taipai is the long delivery time.
Check your plug to see how you are running now, probably be a little lean. If you intend to go open filter just order a 88 jet at the same time and put that in rather than do the jet to 82 now.
Keep any eye on tyre pressures, soft tyres lose you speed and are dangerous.
