Super 8 / Re: 2012 Kymco Super8 50T Derestrict Recipie for 42+ MPH
« on: June 23, 2013, 03:35:15 AM »
No I have not.  It has been working well without it so I haven't been pressed to do it as of yet.  However I will have some time next weekend so I may give it a try then.  I'll let you know.

Super 8 / Re: Lady Rider Joining the Super 8 Family. Exhaust question
« on: June 04, 2013, 03:16:14 PM »
Pmoney I installed a Leo Vince ZX-R pipe and it made the performance worse.  I couldn't figure out why.  I added a high flow air filter, a 17.5mm carb, a longer belt, a Malossi 70cc conversion and still it had worse performance then when it was stock (stock with a smooth boss and 82 main jet that is).  I tried different weights and springs and nothing helped.  Finally yesterday I said screw it and put the stock exhaust back on.  Now the scooter flies.  It has great take off and pulls strong.  It topped out at about 44mph via gps and I weigh 215 pounds.  The difference is amazing.  So instead of spending money for an exhaust you can get the 70cc conversion instead. It is actually cheaper than the exhaust.  You can use the code SUMMER until June 8th 2013 and actually get 25% off so it is super cheap at $120 here  http://www.spi-parts.com/70-cc-big-bore-kit-for-kymco-people-50.html  Even without the code this is the cheapest place I have found this kit.  I am running a 105 main jet with this kit, a high flow air filter and the stock exhaust.  I also have a longer belt and unrestricted rear drive pulley but I don't know that they make any huge difference.  Either way the drive pulley can be gotten for about $25 so it doesn't break the bank.  I also have polini clutch which does allow the bike to rev higher before engaging.  This helps take off but shouldn't really have any impact on top speed.

Oh and if someone can tell me why the Leo Vince ZX-R Exhaust isn't helping my performance I'd love to know why.

Well I finally got mine working today and I have to agree with most of what you said.  The only thing I don't agree with is the idle screw mod.  Mine works fine without doing anything to the idle screw.  Idles and starts up just fine. 

I kept doing mod after mod to my scoot and could not figure out why it didn't work.  Turns out it was the Leo Vince ZX-R exhaust that I bought.  I took it off and put the stock exhaust back on an now my scooter takes off.  I hit 44mph and I weigh 215 pounds.  Here is what I am running
 
1. Free flow Air filter - Link below but I have to say the one Complex has looks much better

2. I have a 105 main jet in the stock carburetor.  I am going to try a 110 to see how that works
3. Malossi 70cc kit
http://www.spi-parts.com/scooter-parts-performance/kymco/kymco-50cc-scooters/kymco-super-8-50cc-2-stoke-air-cooled/70-cc-big-bore-kit-for-kymco-people-50.html
4. Polini racing clutch.  You don't really need this item.  You could simply get some stiffer springs and put them on your stock clutch.  I am using the polini green springs.  I have them adjusted to the middle since the clutch I am using is adjustable.  You'd probably be fine with the stock clutch and springs but your take off may not be quite as good.  Overall though top speed should be the same. 

I have the malossi variator on mine but I don't think it really does anything.  As long as you have the smooth (listed below) I think you will be just fine. 
http://www.racingplanetusa.com/drive-face-boss-vario-bushing-naraku-racing-unrestricted-20x38mm-p-336-1.html?cPath=2_21356_21360&sessID=5e3045ead88f407841faf40ebe9595d7

I don't know why the Leo Vince ZX-R exhaust does not make the scooter run any better.  I even installed a 17.5mm carb and that did not help.  The performance was the same as without it which was worse then when the scooter was stock.  I am curious how it might help with the stock exhaust but at this point I am happy with the stock carb. 

I do also have a longer belt and I got a rear drive pulley that doesn't have a restriction on it but at this point I can't say if those really help.  I say this because my performance seems about the same a Complex and he does not have either of these items.  I did get to 44 mph so maybe they helped a little but then again it could be the larger main jet.  I don't really know.  If you want to see what drive pulley and belt and some pictures you can see them here http://www.kymcoforum.com/index.php?topic=455.msg97422#msg97422

I also tried a Mallosi red torque spring with 9.5 gram and 10.5 gram weights but I found that I liked the stock 8.5 gram weights and the Mallossi white spring better.  The white spring seems pretty close to the stock spring so once again you could save some money and avoid that one too. 

If anyone has questions I would be happy to answer them for you.  I don't want anyone going through what I went through.  I will even talk to you on the phone if you want to go over some things.

Super 8 / Re: Instructions for de-restricting Super 8 50cc

Well I found a place that has the belt that is 10mm longer and all other specs are exactly the same.  You can get the belt here http://www.partsforscooters.com/106-82_Gates_Premium_Belt?sc=34&category=132699

Here are pictures of what the restricted torque converter looks like and what a non restricted one looks like.  I found these pictures on another posting so they are not mine.  But my super 8 has the same one.  The restricted one is pictured first.

From what I have found the Super 8 is restricted in 3 ways now.  I do not consider the exhaust to be one of the restrictions.  To me the stock exhaust is just your basic street legal exhaust.  Here they are restrictions:
1. Vario bushing is restricted.  It needs to be replaced with the item below.  The item below also comes with just about any aftermarket variator kit.
http://www.racingplanetusa.com/drive-face-boss-vario-bushing-naraku-racing-unrestricted-20x38mm-p-336-1.html?cPath=2_7564_7570&sessID=a3cb0a9acd42e1de8ab2acd74aefac2d
2. The main jet is to small.  It is a size 70 and it needs to be around at least an 82.  Larger if you have a high flow air filter.  Here is the type you need
http://www.racingplanetusa.com/carburetor-main-jets-keihin-p-306-1.html?cPath=2_21356_21358&sessID=e06f4cd7ac9a375bf44769d106b6f40a
3.  Here is the one most of us are unaware of.  I just figured this out very recently.  The rear clutch torque converter is also restricted.  It has a small welded lip towards the middle that prevents the belt from going all the way down.  It basically work just like the vario bushing but on the opposite end.  By not letting the belt travel all the way down it is like trapping the scooter in a lower gear.  Remember if the belt can't travel all the way down on the Torque converter that means it also can't travel all the way up on the variator.  The magnifies the problem.  I will add pictures of this below.  The restricted picture is first.  Here is what you need to replace.  Here is a cheap one from ebay.

Here is a more expensive one.  I can't tell you if it is any better however.

Here is an even more expensive one but this one does come with a better clutch.

You could also just buy this piece instead of a whole new clutch pulley assembly as well
http://www.racingplanetusa.com/torque-driver-naraku-sport-torque-converter-secondary-slider-naraku-sport-p-6702-1.html?cPath=2_21356_21360&sessID=5c69a3307e493fc4ab67901e4b1a739a

Pimpy has mentioned that he got a longer belt as well.  I have no idea what Pimpy belt Pimpy has, however I did find a belt that is 5mm longer and just slightly thicker at the bottom.  This belt will certainly work as it is actually for the Kymco Super 8 4t.  The Super 8 4t and the Super 8 2t use all the same variator/clutch parts so you know this belt will work. 
http://www.racingplanetusa.com/drive-belt-malossi-xkevlar-kymco-4stroke-p-8266-1.html?cPath=2_7564_7570&sessID=a3cb0a9acd42e1de8ab2acd74aefac2d

My new torque driver assembly will arrive tomorrow so I will let you know how it all goes.  My scooter is still a work in progress but as of tomorrow I will at least have all of the restrictions taken off of it.  I also have the new belt on order so I will let you know if that seems to make any difference.  To be honest I can't see it being worth more then 2-3mph at best but that is just a guess.  I am going to add a 70cc bbk conversion after all of this but I am going to get my scoot set up as a 50cc first before doing this just a learning experience.  I will post up all of the mods when I am done so that people will have something to use a reference.  I will also post up after I have the bbk all set up so that people will have a reference for that as well.

Super 8 / Re: Help me tune my bike KymcoForum! :) Carb Tuning!
« on: May 15, 2013, 02:07:58 PM »
I have the same pipe and I am working on mine now.  I have a K&N style air filter and with that a 94 main jet was too lean.  I went up to a 98 and I think that looks to be a little rich.  I have not put in the 96 yet but that is probably about where it should be.  If you are worried about being too lean with the Stage 6 air filter you could just modify the stock air box by drilling some holes in it rather then using the new air filter.

Pimpy can you specify on belt size and pulley. We are trying to get our scooters to reach 45 mph
thank you

Since Pimpy is not responding I will help you out.  What I believe Pimpy got was a new clutch assembly.  The Super 8 is restricted in 3 ways now.  Here they are

I have all my parts on order so I will let you know how it all works out when I get the clutch assembly on there.  I had upgraded everything else and I could not figure out why the scooter would not go any faster.  I could tell it had the power but for some reason it felt like it was just stuck in a gear.  After a bunch of research I figured out it was the torque converter.  I ordered one today and hopefully I will have it by the end of the week.

Super 8 / Re: Does a 2012 Super 8 50 2T have any type of CDI speed regulator in it
« on: April 18, 2013, 03:30:42 PM »
I received my de-restricted CDI yesterday and I popped it in.  It does sound like it is revving higher now but maybe only by about 1000 rpms.  Top speed doesn't really seem any different maybe like 1-2mph.  However it did seem to help a little with acceleration so that is nice. 

My exhaust should be here tomorrow and hopefully I will be able to install it tomorrow as well.  I am hoping for the exhaust and cdi to work well together.  I'll let you know.

I was told that it does and it limits the engine to about 8,000 rpms.  I ordered a de-restricted CDI that is supposed to up that to about 11,500 rpms.  I should have it in a couple of weeks so I will post up if it helps out or not after I receive it.

« on: April 12, 2013, 04:29:44 PM »
I just ordered a Leo Vince ZX-R exhaust.  It was shipped today so when I receive it and get it installed I'll let you know how it is.  I also have a bunch of other items coming so but I will put on the exhaust first to see how if it helps out all by itself.  I ordered the pipe here http://www.spi-parts.com/scooter-parts-performance/kymco/kymco-50cc-scooters/kymco-super-8-50cc-2-stoke-air-cooled/leo-vince-hand-made-zx-r-exhaust.html     If you use the code ZUMAFORUMS you get 10% off.   

I also have a new carb, 70cc kit, variator, clutch, and de-restricted CDI coming.
