Scooters - 50cc => Agility 50 => Topic started by: OregonDad on February 10, 2012, 08:18:42 AM

Hi all,
My son has been asking for a scooter for his 16th birthday this month, and my in-laws gave him their 2008 Agility 50 today. It has 6050Km on it and has some cosmetic body damage from sliding on gravel. The original seat hinge was busted when broken into, but my father-in-law replaced it with a brand new seat. He also said the oil and spark plug both need changed, so I will need some guidance for that. I plan to leave it restricted until summer since he is only going to be driving to and from high school. After school is out for the year we can notch the cdi for safer speeds on 40mph roads.
For now, what is best to use for cleaning up the plastic and metal body parts?
Thanks,
OregonDad

Notching the cdi wont derestrict it, you need to replace the drive boss for a smooth one, and fit an 82 main jet in the carb instead of stock 80 size. Cdi cut is optional, i did it on my 2008 tho.
I just use car wax and polish on my scoot and back to black type plastic moisturiser on the black plastics every month or 2. Spark plug and oil change are both simple jobs so if you can use a spanner and socket you should be fine.

A good buffer will make easy work on the waxing. Use 3m RESTORER wax. It has a compound in it to remove the oxidized layer of paint. This is a marine wax so it will last about a year on the road. http://solutions.3m.com/wps/portal/3M/en_US/Marine/Home/Products/Catalog/?PC_7_RJH9U5230GE3E02LECIE20S4K7000000_nid=GS0GCNRWYWbeH8PTZGX97Rgl (http://solutions.3m.com/wps/portal/3M/en_US/Marine/Home/Products/Catalog/?PC_7_RJH9U5230GE3E02LECIE20S4K7000000_nid=GS0GCNRWYWbeH8PTZGX97Rgl)

good choice of scoot. teach him safty and how to ride the scoot right.becarefull with the front brakes so he wont go head over heels. go slow and easy tell he can hadle it good. Have fun there kid.
-
Notching the CDI is the simplest thing to do and replacing the drive boss to a smooth one is very simple also ( you will need to borrow an impact wrench tho ).Other than that and maybe an #82 main jet is all you can do to improve speed.You will have people on here telling you to replace this and that but dont bother. I've done it all and frustrated the hell out of myself for almost no gain. These 50cc scoots are for enjoyment so dont let it become an obsession to reach an unreachable speed. Happy scooting and we'll see you around the forums I'm sure.....Dale P.S. I'll be moving up to the Agility 125 forum as soon as the weather breaks

There are many other things you can do to get another 5-10 mph if you want to put in the time and have the patience but fine tuning is a long slow process, sometimes you go back before you go forwards. No 2 scoots are exactly the same so what works for one may not be perfect for others. Still 45mph on flats is possible as is getting over 50 downhill, there is video proof to show it done.
For me tuning is fun, not frustrating, but i admit at times you wish you never started. Once yoy get a few mph extra tho it makes up for it. Its all down to what you want from it and how you plan to use the scoot. For me its just a big boys toy to play about on and get to work, if you have no time or need or are not mechanically experienced i would stick with just the boss, 82 jet and cdi. Realstically after that you should get 42mph at least.

..this is a false staetment...it is possible to run 60 mph indicated on an A50..been there, done it...
..no, it isnt easy to achieve, but perserverance pays off... ;D

There are plenty of videos on you tube showing how to change the oil on gy6 engines try this one
HOW TO: GY6 139QMB Scooter Oil Change (http://www.youtube.com/watch?v=Kz9Nm4MplYA#)
i use castrol 10w40 4t fully synthetic racing oil although semi synthetic is fine basicly its just use the best you can afford. Dont forget to change the transmision oil also, this is another easy job and only needs doing every 5000km again plenty of vids on you tube for reference hope this helps...
-
I saw kisbee's signature... IF IT IS NOT BROKE DONT FIX IT:) Get to breakin'

Thanks all. Since this is our first scooter we are going to take it slow. The plan is to change the oil and spark plug, wash and wax the exterior, learn to ride at below 30mph for a few months, notch the cdi at the beginning of summer and replace the drive boss near the end of summer. I don't plan on changing the carb jets since he does not need a top speed of over 40mph.
The first thing he asked for after riding was better mirrors. Any suggestions?
Also I would like to get him a windshield to keep spray from other vehicles out of his face.
What soap do you use to get greasy road grime off of your scoot? Simple Green? Ivory dish soap?
Thanks.

Good safe thinking there Dad ..............(..DONT FIX WHATS NOT BROKEN)
-
I gotdecent quaity mirrorsfromebay which are much better than the smalstock ones,sure it was an 8mm thread,most are a standard size and wijust screw in.
The cdi cut will only give 1-3mph increase, the boss around another 9-12mph,taking it to around 42-43mph if algoes well.The jet change wont give you any more speed but will stop you running lean and possiblly damaging the engine after you do the smooth boss and get upto riding at WOT (42mph). Some are fine on the 80 jet but most usually go up to 82,i did anyway.
Good idea to keep it restricted till he gets used to it. I kept mine like that at 1st but i ony lasted maybe 3-4 wks before i felt it was too slow. Once hes experienced enough he prob wil want the litte bit extra top speed.
You can get visors on ebay too that fit,both tall and shorter length ones,or bike and scooter shops or onine scoot shops wil do them.
Heres my ebay mirrors,cost me about £9.50 delivered to the UK,i think. My home made visor is in the pics too http://www.kymcoforum.com/index.php?topic=5166.0 (http://www.kymcoforum.com/index.php?topic=5166.0)

Thank you for the oil change video. Is there a video that shows how to get at the spark plug?
I like those larger wing mirrors, but the Chinese seller will not ship to the United States. Does anyone know of a reputable seller here in the States or who will ship here? Looking for larger wing mirrors, a drive boss and a small clear plastic wind screen.
He did some practice today up and down our suburban residential street. He leaned too much to the left while doing a u-turn and fell over. Bike and kid were undamaged. The engine stopped when he tipped over, is that a safety feature or did the carb just get flooded?
That prompted his next request, a "cool" looking black and white leather riding jacket with reenforced elbows.
-
Just flooded! Look at ebay for mirrors. There are hundreds to choose. Many US sellers can get them to u in a week. Your posts are 8mm threads/standard rotation. http://www.ebay.com/sch/i.html?_from=R40&_trksid=p5197.m570.l1313&_nkw=scooter+mirrors&_sacat=See-All-Categories (http://www.ebay.com/sch/i.html?_from=R40&_trksid=p5197.m570.l1313&_nkw=scooter+mirrors&_sacat=See-All-Categories)
Don't bother buying "pricey" ones as they get broken more than any other part.
-
Dont want to sound like i work for them or something but i got 2 bike jackets off ebay too. Both 2nd hand but in good condition, i didnt want a shiney new one anyhow. Got both for a reasonable price and saved a load on them compared to buying new.
Look for an armoured jacket, elbow, shoulder and back armour if poss. I rarely ride without my jacket now, having slid down the road a few times i know its better to wear leather than not. He will need gloves too if you dont already have them.
-
. Is there a video that shows how to get at the spark plug?
the get to the plug you have to take the seat off 4 bolts and the pull but becarefull the plastic
can be a pain.
-
I just use a lot of "elbow grease" and some good soap to wash my scooters. I do also use "purple power" on harder dirt but am quick to rinse it off.(it CAN "chalk" some items but no where near the "chalking" you get from "mean green". Works good...
With the metal parts, you can use a scotch brite pad or a "s.o.s." pad. Carb cleaner and s.o.s pad is GREAT for cleaning my pipe to shine again..
-
Going for that brushed aluminum look Bats? The 3m restorer wax I mentioned does a good job on metal bits as well. Gets off road grime/grease/minor rust. Just need to add the elbow grease Bats recommends.

YES that be it.

I found the Kymco boss in a plastic bag under the seat.
Signed my son up for a Basic Rider Training course, but it does not start for six weeks.
-
Good for you both O'dad! The more "schooling" one gets the more pride they carry with them. KUDOS!
-
good to here .let him drive in the neighbor hood close to home .Let him get use to turning and stoping and to get to know the scoot a little. good luck to both you. Get your self a scoot dad and ride along.

Steido, tell me more about that visor. Where does it deflect the wind to? Without a visor the wind is directed right under my helmet. Also does anyone know where I can get a visor particularly for the AG 50? It looks like the AG 50 City sold outside of the USA has a visor, but I know way of purchasing one here in the U.S.
-
Encya its off a peugeot originally i think, it was going cheap so i put a bid in and won it hoping i could adapt it to fit. When it came it seemed almost perfect in size but i had to cut and file the bottom edges to suit the shape of my agility headset top better and get it to sit the way i wanted. It is set at a little steeper angle than my agility headset top was so it deflects the wind up more away from my neck. To be honest i put it on just for the look but it does seem to work a little and it also keeps the rain off the gauges et. a bit when riding. I just used spacers i made up to set it and bolted thro with long nuts and bolts to secure it. Had to drill 4 small holez in my agility panel to fit it.
There are generic visors that fit but the ones i saw were between £40-£90 so i just made my own. Didnt want a large visor anyway.
-
A spot opened up for Rider Training this weekend so I signed him up. They are going to let him use his own scooter so we had better clean it up. The left front blinker went out so I need to see if it is just the bulb or a fuse. Our new "City" style mirrors arrived from China, thanks streido, so we will put those on after school today also.
I am still debating which windscreen to get. Puig 991 Sport or 992 Touring.
-
If just one blinker is out it will be the bulb.
-
Personally i dont like the larger full size screens, they just shout grampa to me, but i can see their practicality if you live in a wet or cold climate. If you do go larger i would get one that keeps the wind off your hands as you ride too, my biggeat issue in winter is cold fingers rather than rain, even with gloves and liners my finger tips get cold at times.
Why not wait till hes up and riding then see what he thinks?
-
I was thinking the the touring was a good compromise between full size and sport screens. Still have not ordered one yet. Installed the new mirrors and they make a huge difference. Got a new blinker bulb at the auto parts store and asked for 15W40, but they only carry that weight in gallon jugs. I was also going to get some gear oil, but I don't know which type/weight to buy. Got home and replaced the blinker bulb then noticed that the headlight only works on high beam. Back to the auto parts store again tomorrow.
-
I use NAPA Synthetic 70w90 gear oil. I believe the 4t's use standard motor oil for the trans. Look next to the fill hole to see if it states "Motor oil". If not the 70w90 is good.
-
Picked up some Castrol 80W90 gear oil. The stores here only sell 15W40 in gallon jugs, so is it ok to use a quart of 10W40 instead. I will probably get a synthetic for the motor oil. Good news, my son passed his basic rider training course this weekend. Now we are just waiting on the headlight bulb so we can take the scooter down to the DMV for a safety check before he can get his Moped License.
-
I believe the 4t's use standard motor oil for the trans.
..90wt gear oil in both my 4ts oem...
-
I could not find straight 90 locally, so the consensus is that 80w90 gear oil should also work.
-
..oh yes...70 or 80...
;)
-
Yes. Four years of abusing a 50/70/90cc trans w/ out a tranny issue. (knock on wood)
43,582 miles with 70/90 (NOT Km's)
-
...HAA!!..
..46,000 MILES here wit no tranny issues!
:o
-
Show off!
-
Update. We finally got through the DMV maze and my son passed his moped skills test this morning so he is now licensed to ride solo on public streets.
Since getting the bike we have: replaced the mirrors with City style ones off eBay (thanks Streido), replaced the headlight bulb, notched the CDI and changed the oil.
Sitting in front of me I have the smooth variator boss, the 82 jet and 5.5gram roller weights (thanks Exe). Waiting for my electric impact driver to get here from Harbor Freight to tackle the CVT mods.
We also need to change the spark plug while I have the carburetor off. Should we use a CHAMPION-P-RZ9HC or an NGK Iridium plug?
-
If the $3 or $4 difference is not a financial problem the iridium is a superior plug . Good luck .
-
x2 go with ngk
-
Mass Iridium to all!
-
What model number of NGK?
-
CR7HIX Agility 50 4t
-
Mass Iridium!!!! Personal experience to change my opinion!!!
-
Has anybody tried the hotter plug...CR8HIX?
-
It wont be necessary as the iridium has a hotter spark to burn more completely. The hotter plug MAY create detonation from the excess heat in the insulator.
-
Another plug question. Several reviews of the NGK say "Did not come with the tip that screws on to the top of the plug. useless with out it." and "The plug comes with a threaded end and I needed a terminal cap to use it with my scooter - that was hard to find - parts store guy stole one off another plug and gave it to me - I suggest (the manufacturer) putting one on the plug and letting us (the consumer) take it off if we don't need it, instead of making us search for one if we do."
Having never changed a scooter plug before, I have no idea what the reviewers are talking about. Does the NGK (7544) CR7HIX Iridium IX Spark Plug come with everything I need?
-
The little screw on nipple does come with the plug. Yours was simply missing. All plugs use one, and some are now molded on, and do NOT remove.
The new iridium will have one.
