Help a noobie out! Upgrade Questions...

[shubonker]

Okay, so i'm completely overwhelmed with the wealth of information that is on this site.  However, i cannot seem to get a few questions answered by simply using search function so please don't kill me for asking a questions that has probably been answered already.

For my currently stock agility 50 2009, with unrestricted cdi:

1. What size jet should i be getting? 6mm?  Should i go with #86?  How do i balance air flow so that i don't run "lean"?  How do i know if its running lean?

2. Where can I buy the variator boss in the US?  I can't seem to find it by itself, but i see a lot of kits that include it!  I just want the unrestricted boss! 

3. Do i need to have an impact driver to install the variator boss?  Would a regular wrench and elbow grease do the trick? 


Thank you so much for your help!

Ok so i've figured out questions 2 & 3.

I found the bushing here http://www.partsforscooters.com/Drive_face_spacer_qmb139?sc=9&category=469 (thanks to dark13).  Also called variator boss/ variator bush/ drive face spacer. 

And i also found out i DONT need impact driver to get the bolt off from the variator.  And that i should use blue locktite when reinstalling the variator (after putting in new boss). 

Now if someone would tell me how to tune the carb via jet size and air filter, it would be greatly appreciated! Thanks!

If you are not changing anything with the exhaust or air filter you should be just fine with the stock main jet.  You only need to increase the jet size if you are increasing the amount of air in or out.  By just derestricting the cdi and doing some cvt tuning you are not changing anything with the air/fuel mix.  You can check your fuel mix by doing a plug chop, ie. reading the spark plug.  You should be fine though!

[shubonker]

In that case, what's a good air filter and jet combo?

[Shaka]

You might check out Wordslingers posts.  I'm not sure what jet he is running, but he and I are both running K&N air filters.  I know his Agility tends to run bigger on the carb jetting for some reason too.

Cool, i just looked up how to do a plug chop.  One question though, would you check it immediately after you hit the kill switch or could it wait til you run back to your garage/work area? 

Shaka, also, i would love to see what kind of mods you've done to your agility and what your top speed is?

Thanks shaka! Btw, you've been extremely helpful!

No worries!  I don't actually have an Agility.  I have a ZX50 that's pushing 60mph, I've just hung around here long enough to learn the Agility pretty well!  The basic principles apply to all scoots for that matter also!  On the plug chop it doesn't matter if you wait to "read" it, but you have to pull the plug out immediately.  Make sure you bring your "normal" plug with you to switch it for the ride back home.

...well, it seems the forum has been busy since i've been away...

..welcome, shubonker, to the best forum in th' world!!

..along with your derestricted boss, you should get you some lighter rollers...

..i'm partial to the 4.7 grams, but i think imma go to 4.5 when i replace these...

..it would benefit your scoot to go up one size stiffer on the main torque drive spring in your clutch...

..the stock spring is rated @ 750-800, i think...

..i'm currently running a white Malossi "1000" main spring, but I want to give a 1500 a try...

..also, you would benefit from some stiffer fly clutch springs...

..i'm currently running Leo Vince +15% springs...i've tried the +50%, but i didn't like how high i had to rev my scoot to get it going, and the 15s seem to accelerate better than the 50s...


..all these mods will make your scoot performe much better than the stock setup...

[shubonker]

Cool wordslinger, thanks! Will order some springs later this week.

Any other mods i can do to up the top speed and accel?  My ideal performance would be 45mph as a top speed and better acceleration.

[wordslinger]

..a free-flow air filter, as said below along with an increase in jet size...

..but those things in my last post will get you better than 45...and the lighter rollers and stiffer springs will make you go WOW on your take-off...

..i saw you ordered rollers already...

..what weight??

[wordslinger]

..a really good upgrade would be a Malossi Multivar variator....

..it comes with the 1000 torque spring, but it also comes with stock 6 gr rollers...which are too heavy...

[shubonker]

I bought 5g rollers. 

Will check out the malossi variator!

[wordslinger]

...you'll get a bit better acceleration with the 5gr rollers...

..i harped on 5.5s for a long time, til i got the 4.7s...

..and i believe the 4.5s an da 1500 main spring will give even better accel..

..it's all about keeping the revs up on these 4ts...

[wordslinger]

...aannnd imma say it again, because i've harped on it so much in the past...

...4t scooters require frequent oil changes and even more importantly...


 


..here we go...

 

...correct valve clearance.....

[shubonker]

How do i go about adjusting the valves?  I've already ordered oil for when i get my scoot back from the dealer
