About the same...
The speed hasn't really changed much.¨
I have just tried upgrading the carburetor to a 20mm, but the speed still stays the same.

Its not the first 139qmb engine I've messed with, but for some reason this scooter just wont turn like the others.

What kind of speeds are you guys seeing with this scooter?
Are the gears just weird, to compensate for the large tires?

Sure, but the rpms will drop even more.
I have purchased a naraku unrestricted cdi, waiting for it to arrive.
But I have heard some people having trouple with it.

I really cant see why, it should't work?
The cdi is sold by most dealers, if it were sh** they would probaly stop distributing it.

Super 8 / Cdi Still Restricted!
« on: May 19, 2018, 09:20:37 PM »

I have remove one of the little purple wires from the cdi box.
New 38 mm glide bushing.

With the bike fully warm, I tried really going wot down a slope.
With only a slight increase in rpms and top speed. By the end of the slope still going wot the bike started to hesitate and backfire.
So the bike must still be restricted in some way, or possibly the cdi has gone bad.

The purple wire cut is suppose to move the rpm limit from 7500 to 9000 rpm.

Hear is a video (not my bike) showing that there still is a restricton when the wire is cut:
First: original cdi with the wire cut: 

Second: Aftermarket unrestricted cdi

The question is what to do now?

Timing is correct and valves are adjusted.
My setup:
72cc gy6
47mm cylinder head 21 in / 19 out
Performance camshaft
Polini variator 4,5 gr
Unifilter
Leovince exhaust
15% stronger torque spring
Stock carburator

It's pretty weird.. Naraku is a good brand, that cdi should work.
Did you talk to the dealer, about the naraku cdi?

I think the cdi is controlled on a kymco super 8 4t, by the cdi.
Some people have reported problems with the choke not coming off, when using a aftermarket cdi.
Have you tried to feed the choke 12v direct from the battery?

Cause it sounds like the choke is still on.

Kind regards

Super 8 / Calling All Experienced Tuners!
« on: May 18, 2018, 02:02:08 PM »
Hello.
I am writing to you about some problems I have with my scooter.
Kymco super 8 4 stroke 72cc.

I hope you guys can help me out.
My scooter do not really reach high rpms when I give it full throttle, as you can hear in this sound clip

Which in turn limits my top speed..

I have removed the following restrictions:
Cut one of the small wires at the cdi box.
New sliding tube and new polini variator 4.5 gr.

In addition to a 72cc bbk I've also fitted a larger cylinder head with bigger valves. I have had to increase my main jet size, following the installation of the new bigger cylinder head. Right now I'm running with a 110 which I think is pretty high. I have also tried higher and lower main jets with no increase in performance. The rpm does not go up nor does the top speed.

I have thoroughly checked for leaks but found none.
The scooter starts immediately and keeps idle fine.

Timing is correct and valves are adjusted.

My setup:
72cc gy6
47mm cylinder head 21 in / 19 out
Performance camshaft
Polini variator 4,5 gr
Unifilter
Leovince exhaust
15% stronger torque spring
Stock carburator
