Scooters - 50cc => Super 9 => Topic started by: czechphotoguy on April 07, 2014, 09:14:08 PM

Yes I know this isn't the place to start with intros but after a almost 9 year hiatus I have dove back in and purchased a 2004 blue Super 9.
Got it at a great deal here in Denver and I plan on doing to it what I did to my old 2004 that I had to sell back in 2007.
I knew I would get one I just didnt know exactly when I would get it. So next I plan on going out and purchasing all the parts and kits to get it up to the 70cc speed kit.
Do any and all of you have suggestions of where is the best place to go to get the parts and which place will have a "full" kit to put on the bike?
I have all the tools and the patience to do the work myself as I did it before but when I sold the old bike I also included all my notes and stuff for my upgrade to the person who purchased the bike.
Thanks,
Ross

Dunno who sells stage kits for the Super9 specifically but I get my parts from Racingplanetusa, mopedhospital and stooterworks

Stooterworks or Scooterworks out of Chicago?

Yup that was a misspelling. Heres the site I was talking about

Thanks for the initial help...now the real questions.
Originally I wanted to do the 70cc upgrade but honestly from how it's performing I don't know if I really need it.
It's running a good clip between 40-50mph depending on grade of hill.
So if I don't want to do the 70cc upgrade what all should I probably do to it besides the exhaust?
Variator, Kevlar belt, clutch...etc?
I am a tall guy 6'3" 230lbs and I am going to use this around Denver as my street photography commuter as driving my car just becomes a hassle when I want to park and shoot.
A lot of the streets I traverse on are 45mph so I would like to up-tune the scoot so I can keep a constant 45mph+ speed.
Thanks for the help

Start with exhaust, variator and contra spring. Dont forget to upjet. IMO this is the best setup you can do that is bolt on beside a BBK.
-
Do you have specific part numbers or such of which variator and other parts to get?
Also as far as exhaust goes. If I take the stock muffler off and it still has the restrictor "Venturi" or washer thingy at the end of it that goes into the engine head. Will it help much if I do take that off with a disc grinder and un-restrict it?
And what in the aftermarket exhausts make them be better than the stock?
Ross

Go to racingplanetusa.com and enter your model for specific parts. I dont know of the specific restrictions on your scooter. Dont forget with any change in air going to the engine eg new exhaust you have to upjet the carb

245luigi... You have the right approach but you deal w/ the most F'd up suppliers on the planet!
Go to Louie at SPI Scooter Parts International
http://www.spi-parts.com/ (http://www.spi-parts.com/)
Tell him Zombie sent ya from Kym Forum. Pm me and I'll give you my account name w/ Louie so you can get wholesale pricing once you sort out what you need
You can also talk to Josh at scooter invasion or The Scooter Garage or PM/email Word Slinger from here.
They have the part numbers, and all the different levels of performance you will want for that bike

This is why I need your infinite wisdom zombie!
So whats the lowdown on racingplanetusa then? I havent had a problem so far. Their prices are high but they carry parts that I havent found else where and are willing to let me return parts if they say they'll fit my bike but they end up not.
-
So as far as the Contra spring is there a specific color that I should get?
Now also understand that I haven't had a chance to look "under the hood" yet at my Sup9 and see what the previous owner did to it. It will keep a good constant 45mph on the flats and I can get to 55 on slight downhills. So I know something has been done to it so far.
My goal is more top end speed. I don't care about off the line as I really am not using this as a racer. I want to also have better constant speed when going up hills.
I plan on tearing apart the bike this weekend and looking into it and seeing what I already do have and then go from there.

They constantly lie about what is in USA inventory. The site says it is in stock until you place the order, and THEN they tell you 2 weeks shipping (over seas)
Stage Six parts are the only hard to find parts in the US but there are other sources.
The other issue I have is you can save HUNDREDS of dollars but they do not volunteer the info. Make up ANY company name, and list as a wholesaler w/ them. They require NO numbers or paperwork because they are Germany based. Just pay your sales tax upon checkout.
I just don't like being lied to every time I place an order. If you don't stock it... Don't list it as "In Stock"

The best suggestion I have is do a compression test, and see what you have. It should be 120psi or better.
Then as you said make a list of what is NON OEM on the bike.
45 flat sounds stock to me so you may have alot of options.
How does acceleration feel/sound? Do you have one steady rpm from a dead stop to full throttle? Or is there a point it feels like it "shifts" gear.
What are the top speed rpm's? What are the cruise speed rpm's? Factory carb/airbox? Factory pipe?
Most important... How much mulla ($$$) do you want to put into it?
No matter what you do to it 55-60 is about top speed for the engine/gearing. Josh or slinger would know if shorter gears are available.
Sooooo Bottom line is you can make more power, and get better Accel., higher cruise, and smoother transition of the cvt but to know where to begin you have to answer those questions i posted

Acceleration feels constant to me but I do feel at certain points it does "shifts gears".
Haven't checked the top or cruise rpm's so I will test that out this weekend when it's warmer.
I will check and do a compression test on it this weekend also.
It's the factory air box and pipe. Will look at the carb but I would guess it's stock also.
I was also planning on checking on the roller weights and figuring out if they we're stock or not or at least finding out what weight they are.
As far as money goes, lets just say I hate the word "frugal"
;D

You are on the right track... Since you feel a "shift", that is the torsion pulley in the rear opening. There is a fine line to balancing the CVT correctly. You want that pulley to open as LATE as possible. BUT the rollers will have a definite effect on that timing.
Do the Comp test first thing. Then determine if your cruise/top end rpm's are correct for your weight, and the area you ride. That will determine if your rollers are correct. Lighter makes higher rpm, and heavier makes lower rpm.
After you get the correct rollers you can decide which contra spring is needed. Usually (but not always) the lightest aftermarket = OEM, and they get stiffer from there.
For most people 180-200 lbs. the two stiffest springs are what is needed. I have 2 bikes, and both have red stage 6 (stiffest you can get). One is a 4T, and the other a 2T so the bike doesn't matter. It's about weight, and momentum.
Engine condition, and rpms will decide what rear spring will work
-
So when I had my last Sup9 in 2005 I purchased it brand new. So I never needed to do a compression test because of that.
So what is the best way to do one now that I have the proper device to perform the test?
Ross

Easy stuff. Kill switch set to kill. Bike on center stand. Remove the spark plug. I use masking tape to hold the throttle WIDE OPEN. Make sure the tester is screwed in quite snug but don't go crazy. Too tight can tear the "O" ring, and give a false reading. Hit the electric start, and give it 5-6 full revolutions. You will see the gauge jump up a little on each revolution. It usually stops increasing in 3-4 revolutions but you want to be sure it is maxed out.
I usually repeat this twice to verify.
If it reads less than 120 but over 90 you are well worn (cylinder/rings/head gasket) but it will need parts before long, and I would address that first
If it reads less than 90 remove the tester, and pour about a 1/4 oz of 2T oil in the cylinder, spin it over 2-3 times with a rag over the spark plug hole, reinstall the tester, and repeat the test. This will tell if there is a score in the cylinder or just worn parts/leaking head gasket. If it comes back up to the good range it is worn parts or a leaking head gasket. If it stays low it is most likely a score in the cylinder/piston
If you are within 10% either way of 120 you are good to go.

Ok well looks like I am going to be doing the 70cc upgrade!
I did a compression test this morning and it averaged about 85psi.
So looks like I need to make a grocery list of things to get.
I found out also that the scoot is all stock and there has been no aftermarket upgrades done on it.
I didn't go out and check top RPM because I know that considering I will be making some major changes to the scoot those figures will completly change.
As a heads up again IM a tall and big guy so I need to set this up for that.
So now I need to know exact part numbers and such of what to put on it so I can get it to "Scoot"!
;D

Call Louie. Tell him Ken McLaughlin c/o Max Marine, Carrabelle Fl./Lanark Village Fl. sent you.
He will take the time to get you set up. Buy your parts on my account for wholesale pricing.
Same goes for everyone here. I respect Louies talent, and he is passionate about what he does. He is a career scooter racer, as well as lead mechanic for team Yamaha (retired) If you are not comfortable buying on my account... Just mention me, and the forum. He will take care of you.
-
I will definitely get ahold of him so I can make my Sup9 "Scoot"!
I'm putting together the "Grocery list" and what he suggests on top of what I "think" I need I will get.
:D
Thanks very much!
BTW...I plan on documenting in photos each and everything I do to the Sup9. I work at Apple as a Creative (Instructor) here in Denver and also shoot professional hockey and lacrosse. So I kinda know a thing or two about making good in depth videos and photo presentations about stuff.
As soon as things start showing up I will start the tinkering!

BTW...
What is the main difference between the Malossi Fly and Delta Clutch?
I know that one is almost double the other in price but I also notice that it looks like the Delta would be more able to tune specific to your style of riding.
I don't know if that is something that I would necessarily need but it would be a nice thing to have if I plan on really dialing in my scoot.
Ross

I just posted a reply to the same question...
The fly is a OEM type, and the Delta is a race type. You WANT a race type for one simple reason (as you noted) tune ability.
Read this... http://www.kymcoforum.com/index.php?topic=11219.msg114956#msg114956 (http://www.kymcoforum.com/index.php?topic=11219.msg114956#msg114956)
I have a six year old Delta the has been on three bikes all using different bells, and it is still on the same shoes that came with it. It is BULLET PROOF! But. The stage6 is much more adjustable for fanatical tuning. I like it better than the Malossi but I have much more power than the Malossi is made for.
Ask Louies opinion, and he will guide you in the right direction. He is NOT a profiteer. He IS a scooter racer.
Tell him exactly how you intend to use the bike, and nothing about whatever fantasy ideals you may have. The intended use determines the components. Fantasy use, and we would all have bi turbo / blowers / Nox, and wheelie bars with a switch to give us everyday riding economy.
Give up a few MPG for a few MPH... Fine
Spend a few xtra $$$ for a longer lived part... Fine
Spend several thousand for Loads of MPH, and longer lived parts... Fine
Spend 100.00 bucks, and expect all of the above... Stupid
Your best spent $$$'s will be on the clutch, and then the jug. and then the pipe, and then the carb/intake.
A good clutch makes any bike perform better.
