Yes it will fit the standard Kymco bulb which is very poor IMO looks different but a BA20D is the right bulb. I upgraded mine to a brighter Xenon look type off of flebay in a similar design. Big improvement in output and visibility.

What bulb did you upgrade to? I've been thinking of obtaining a brighter bulb and somehow making use of the other two top ones.

"With those I will gain more power, but less acceleration and speed right?"
You only gain power in the engine, not the cvt. You can better transfer the power you have to the road tho.
You will gain BOTH acceleration, and top end speed by tuning the cvt correctly.
Since you found the jet an easy task you may want to try a few larger sizes to really dial it in. You may find an 88 works even better. Especially when you can run more rpm's on your cvt set up. You DON'T want the engine to starve. These little scoots run pretty god if you tweak em a lil.

With an 88 I would need an open air filter right?  Also, should I try 6.0g instead of the 5.5g I bought?  How can I tell if I'm not getting all I can out of my scoot with the weights and torque spring?

Installed the 82 jet and what a hell of a difference!  My Agility now accelerates noticeably faster, more power taking off and going up hills, and she no longer bogs down in cold weather.  I didn't expect going from 80 to 82 would make a noticeable difference, but was I wrong.  Now I'm just waiting for my 5.5g rollers and 1000 rpm torque spring.  With those I will gain more power, but less acceleration and speed right?

The Agility 50 takes roller weights, not slider weights, right?

SPI has them... Just call. The owner/person you will talk to is a TOP engine tuner. Listen to his advice... Sucks I forgot his name. I am waiting for three different belts from them right now (back order). 2 from Italy (Malossi), and One from Japan (Bando). As long as you call before 4:00pm your parts will ship same day. Don't forget to mention the Zuma Forum...

Awesome, I'll give them a call tomorrow.  I really appreciate the help.

So, I'm looking at buying these: http://www.scootertronics.com/1000rpmspring.html and http://www.scootertronics.com/okogy650rowe.html

I can't find anything stating that spring would work with my moped, but I'm fairly sure it will. Expensive, but can't find anything else that would be less and just as good quality.

Nevermind, after viewing the customer reviews I will definitely not be ordering from them, but rather from Scooter Assassins.

I can't find a single site which carries 5.5g and a 1000 rpm spring.  This should't be this difficult.

Well, looking at past topics on the clutch spring, some people get a drastic reduction of top speed after installing the clutch spring.  At this moment, my scooter will do max 40 mph, regardless of how steep the hill is, so I'm worried I will loose quite a bit in speed.

Ok, but what size rollers?
