Scooters - 50cc => Super 9 => Topic started by: cblo on July 03, 2014, 04:28:00 PM

Hi all,
I just picked up an 05 Super 9. Great deal. Looking for community ideas/thoughts. This scooter is fast...maybe in the 50-60 mph range?(speedo goes past mph on the speedometer). However it is slow getting there and not as responsive as I'd like( as compared to my 01 Zuma). This Mn weather this year also is making it not consistent. Slight hesitation initially then launches to about 25 mph, slow 30-40 then picks up slowly until the needle can't go no more past the mph on the speedo. As much as I like how fast it is I'd like more up front and consistency too. I believe the scooter is still a 50cc liquid cooled with an Technigas RS pipe and maybe everything else stock. Any recommendations to get this scooter to be a beast? I'm about 130 pounds and ride in Minnesota where it's relatively flat with a few hills. Oh and it sucks going up hills, maybe 20 mph.

I'm sure the experts here will post soon but here are a few thoughts.
60 mph seems high for a 50cc. Mine does 50 but I weight 55lbs more than you,
so maybe. Lets figure you are doing over 50mph on the speedo.
What RPMs are you doing at this speed ?
I would first see what weight rollers you have.
They are too heavy probably, given your lack of take off
but have relatively high top speed.
Also if you have a tecnigas RS70 or RSII pipe, it's designed
for 70cc and by default you will lose some low end grunt, especially
running it on a stock jug.
If you are going up the south face of the Matterhorn it will slow right down but
a regular small hill shouldn't be a real issue. See if the RPMs drop or the speed or both and let us know.
That way we can see how you transmission is handling the load.
You can regain you bottom end by putting the stock pipe back on or change the clutch springs,
contra springs, etc and tuning the transmission to your pipe.

rollers....and doing 60...not sure even in that case
-
I got 60 mph GPS on my cobra with the same engine ( swap ) and tecnigas rs70 pipe,
so yes it is possible but the take off was a pig. But I had all the tranny work too, not stock.
And yes it was 49cc.
-
It must have had higher gears cause i have a cobra with texhnigas 70cc pipe its stock it will run 52 mph gps at 10000 rpm i also have super 9 lc it has airsal 70cc t6 bbk and same pipe it has gears it will run 67mph gps at about 11000 rpm

Weigh your rollers to see what they are. Go down 1-2 grams. Add a stage 6 MKII clutch, and install the Red fly springs.
This will give you a take off RPM of about 7-8k. Just at the beginning of the pipes power band.
Have you done any work on the carb? It sounds like it could be mis-jetted. There should be no stumble.
Your main sounds correct since you can hit a decent speed but the pilot may need swapping out.
Pull the carb, and see what you have. Get 3 sizes up, and 2 sizes down.
You might get a better idea if it is rich or lean by noting how far out the idle mix screw is.
Which end of the carb is the mix screw on? Engine side or air box side, and how many turns out is it?
Forgot to welcome you to the forum...

I think he implied he had the liquid cooled motor swapped into his cobra ^^^
-
Only difference is ac and lc though on those two motors right?
-
I have 05 zuma with athena crank athena bbk athena 15/50 gears del orto 19mm carb and i finally got a super9 lc and i love the super 9
-
Yeah LC and AC but the LC motor runs slightly higher compression and tighter tolerances. I wouldn't put 55 stock out of the question. It's a much stronger engine than the ac version
-
I think i could get my cobra to 55 but i weight 250 but my super 9 will run 67mph gps great scooters i love the feel of tge power and the ride
-
I love the cobra tho, it's like a Kymco zuma, sick stock tach too haha
-
I have all three lol
-
02 cobra 04 super9 05 zuma

You have to use the "Reply" button. The "quick reply" does not support adding picts.
Go to the bottom of the" Reply" page after you post, and you will see "Attachments, and other Options"
Click on that, and a dialog box opens that says "Choose File".
If after posting a pict you get a page stating "Image file too large", you have to re-size it/them. You can right click on the image, and choose "edit". Paint will open, and allow you to scale down the image. Or you can D'load "Image Re-sizer" in windows "Power Toys".
Hope this helped...

I tried wont post it

Trying again

Pic of my new super 9 lc
-
It looks in great shape. Nice!
I mean the pict didn't post. We can't see it.
-
Do know what stock gear ratio is 04 super 9
-
No Idea.
The way to find out is take off the cvt cover, mark the clutch bell anywhere. Then mark the tire anywhere. Turn your clutch bell till the tire does one revolution, and count the turns on the clutch.
I have seen other Kymco 2t's ranging between 8:1, and 10:1. The best ratio for a modded Kymco is 7.1 or 7.3 to one. Any lower, and you need over 100cc's
-
I think the blue's are the fastest
-
I agree the blue ones are fastest lol
-

Are you talking about the plastics or the engine cases?
If it's the plastics... Bring them to any body shop or Marine repair shop.
