i2012 kymco super 8 50cc 2t - beginning of mods

[245luigi]

Try the  carb mod and see what happens. As for the idle jet, get the next size up or next size and 2 sizes up. Nice thing is if you have the "proper" idle jet you will have a little bit more room for tuning should you do other mods etc.

As for the resonance check out http://www.amrca.com/tech/tuners.pdf
search within the doc "resonance" "resonant" Page 92 is where the good stuff starts. Maybe that's it?

Wow - that's an amazing handbook - what an in depth analysis.
That being said - it offers an explanation for the resonance effect - but not a solution.
I am going to try to wrap the pipe from cylinder to the beginning of expansion cylinder with pipe wrap - see if it fixes it.

Which idle jet to get? is this the right jet type below?

Complex,

What are the steps for your idle screw mod? Ive done some searching but cant find anything on the forum.

Also, does your super8 run the PB16 carb or another?

Thanks

Ok - bit of an update:

1. Installed de-restricted Clutch:
http://www.monsterscooterparts.com/qmb139-clutch.html
Comes with much stiffer spring then our Kymco - not sure what performance impact it will have

2. Installed Scooter Assassins Blue (K&N style) air filter with plastic cover
- Bit of an issue with that: - its efing LOUD - I am actually planning to drill out original, and put it back.

3. Installed #100 jet from #90

4. Tried to install #42 Idle jet to solve the cold starting issue - but the thread turns out too big - does anyone know which size idle jet we need exactly?

Here is the thing - I still can hit 45mph on flat - BUT i lost this instant acceleration across the whole range I was so happy with - any ideas guys?

Well guys - I modded my Super 8 so much.....it turned into Aprilia SR50 Factory.....;-)
Got the 2013 model so cheap could not pass it...
After calculating how much my kymco would cost to get to the point i want it,
it actually came up more then Aprilia would cost new - and still Aprilia is a better bike - injection/dual disks/amazing cluster panel/self adjusting ecu/halogen lights/glove box/ better suspension/more comfortable seat.
It also happens to also top out @ 55mph with just standard de-restriction......
Soooooo.....will be putting my 2012 kymco on craigslist soon...seems I was tinkering with it more then riding...
