Derestricting the Kymco Super 8 4T?

[Super8504T]

Right!! To the good stuff it is then 

[sidthesloth]

Yes, I use Shell V~Power when I can. In some towns if they don't have Shell they usually have a Caltex so I will use Vortex. In the car I just use normal unleaded 91ron as recommended by the manufacturer. 80 litre tank is a bit more expensive than a 15 or 20 litre tank. :-)

Yeah it is! Not so bad for me with a 6 litre tank  My local Shell garage at the other end of town stocks V-Power so I'll start usng that from now on, see the difference in MPG.

my normal unleaded is 95, that's the best for my kymco s8 4t

Just want to stick my 10p's worth. My Super is fully derestricted and has an 85cc Big Bore Kit, Big valve matched head, high lift cam, 24mm carb with 105 jet, Naraku race variator and Dr pulley 9.5g sliding rollers, race clutch, 1500 torque spring and a Technigas freeflow exhaust. It will not go above 50mph because of the gearing and as of the time of writing this there is no gearup kit for this scoot.  Kymco use their own final drive gears which are not standard GY6 gears.  BUT.....  it gets to 50mph very quickly!!!  There are only three restrictions on the super 84t which are variator boss has a shoulder on it, main jet needs to go up a couple of sizes and CDI rev limiter...  thats it nothing else!   Hope that helps because anyone trying to break the 50mph magic number...   best of luck!   I think I should really have bought a 125cc   :-)

Oh dear not very encouraging 

The latest update from me.. Order my Leo Vince exhaust.. a size 85 main jet.. race clutch.. Polini Speed Control variator along with around 6.3g rollers. My CDI wire is already cut so I should be doing 50+ Shouldn't I. If it doesnt after all that I'll be baffled??

[Luke.]

not good "/ i have heard of changing the kymco gears though, so it's somehow possible (:

[wordslinger]

a size 85 main jet..

..might wanna think closer to 90-95 with that exhaust...

[Luke.]

what size would i need for a k&m air filter?

Ya if your making that jump I'd order a #90 #95 #100 should put you in the right range,you may also have to go richer on your needle and pilot jets

[Luke.]

i'm not getting a pipe though, just derestricted cdi and derestricted variator, then new jets but a new air filter too?

[art]

If you do the airfilter you will want to do the pipe also they kinda go together,more air in more air out.If you dont want to do the air you can increse airflo by drilling a hole in the air box.A 3/8" hole in front of the airfilter on the box worked great for my peoples 50 stock and an #85 main,if it don't work out for you you can plug it up with duct tape.

[Luke.]

ah i'll forget the filter for now, what do you mean in front of the air filter?

[Super8504T]

What will happen if I stick with a size 85 main jet and Leo Vince exhaust?

Alchemy67, I don't know if the super 8 uses the same gears as the super 9, but in another thread Aeromyst had some gears that would fit only certain models. If you find the thread titled Cloud 9, I think it is in the super 9 section you may get some more info on it.
