Agility 50 / Re: Loss in mpg
« on: April 29, 2009, 03:53:51 AM »
Update on MPG since derestrict:  2 tanks of gas, 93 mpg and 92 mpg.  This represents a 20% increase over the restricted version.  Conclusion:  derestricting increases performance, top speed, and fuel efficiency.   ;D

Agility 50 / Re: Derestricting your Agility CDI

Oh yeah, the link.....

Doh!

I think it is well worth putting the clutch boss in.  The part only cost me 35 or 40 dollars and made a world of difference.  It allows the scooter to perform as it was originally intended, not restricted.  I can't give you km/h references, but in mp/h I went from a top speed of 30 to somewhere between 40 and 45.  You can convert those numbers to km/h for reference.  The only two modifications I have done is the clutch boss and the cdi cut.  I did them both at the same time so I don't know how much either modification alone would make.  The top speed varies according to road conditions, incline or decline, and wind.  I don't think the overall horsepower or torque is affected by these mods, so it still takes awhile to get up to speed.  The consensus is that these two mods should be done first, and possibly changing the carburetor jet (which I have not done) before doing any other mods.  Personally, these two mods are probably all I will do to my Agility 50 for now.  Other options such as a big bore kit, different exhaust pipes, etc., all cost hundreds of dollars.  If I were to do any more mods they would probably be clutch springs, rollers, stuff like that which is relatively inexpensive and gives some benefit.

Here is a link to an illustrated guide to putting an unrestricted clutch boss bushing in an Agility 50.  It is very simple to do and will take about 15 minutes.  The only special tool that is highly recommended is an impact wrench (you know, the ones that are run on compressed air, like the mechanics use).  With the impact wrench the nut on the front pulley comes right off.  Without the impact wrench it would be very challenging to remove the nut.  The bushing makes a big difference.  My Agility 50 now does between 40 and 45 simply be cutting the cdi and installing the bushing.

Have you derestricted it?  I noticed my mileage was down around 75 mpg when it was restricted, but after derestricting it my first tank has given 90+ mpg.

Agility 50 / Re: Performance parts for the Agility 50
« on: March 31, 2009, 11:45:19 PM »
I started a thread in the general discussion forum, not realizing that there was a forum down here just for us!  Anyway, I've owned an Agility 50 for nearly a year and up until last night it was restricted and topped out at 30 mph.  By putting in the clutch boss and cutting the CDI I now get 40-42 mph.  With a little tailwind today I even got up to 45.  The performance is so much better than when it was restricted.  Eventually I would like to add other performance parts, but for the cost of the clutch boss I am very happy with the result.  And I'm a pretty big load, 220 or so.....

General Discussion / Agility 50 Derestrict

First time poster.  I've had a Kymco Agility 50 for nearly a year.  Great little scooter, but 30 mph top speed was getting me down.  I ordered a clutch boss replacement from scootertherapy dot com and cut the rev limiter on the CDI.  Wow!  What a difference.  The scooter is peppier and more importantly I can get 40-42 MPH top speed on a decent straightaway.  The part was $40 including shipping from Wisconsin to California.  It is super easy to change the clutch boss.  It takes about ten minutes.  After considering big bore kits, exhaust pipes, etc., which all cost hundreds of dollars, the 40 bucks for the clutch boss and quick cut with a hack saw on the cdi has to be the best bang for the buck that I can find.  I would highly recommend that anyone with a 50cc restricted Kymco scooter do these two mods first before anything else.  There are lots of ways to get more power out of our scooters, but for the money I don't think you can beat the two I did to my Agility 50.  I don't know for a fact, but I would guess all the 50cc models are pretty much the same.  Here is a link to the site I found with both mods illustrated.  The CDI pictures are kind of crappy, but you should be able to get the idea.  ;D
