Super 8 150 / 2015 Kymco Super 8
« on: February 16, 2015, 11:27:40 PM »
Look what Kymco did to the Super 8!:

http://www.kymcousa.com/showroom/scooters/super8150r/index.html

They took all the stuff that made the Super 8 a Super 8 like the sport bike styling and 14 inch wheels and turned it into an Agility 150.

What a disgrace.

Super 8 150 / Re: what weight rollers to buy
« on: February 16, 2015, 08:43:14 AM »
I've tried 14, 13, 12 and eventually settled with 10.5 gram Dr. Pulley sliders.

The stock rollers are 13 grams.

Super 8 150 / Re: New super 8 150 motors
« on: January 19, 2015, 06:19:16 PM »
Welcome to the forum Louanne,

The only place to get one is Kymco or call around to several scooter shops to see if anyone has one. Guessing you did that already...

You can replace yours with a new GY 6 150 which is a copy of the Kymco, which is a copy of a Honda, which Kymco made for Honda. Got that??

Here's the engine I am talking about...

http://www.ebay.com/itm/150CC-GY6-Scooter-ATV-Go-Kart-Engine-Motor-150-CVT-Carburetor-Complete-Package-L-/310657548005?pt=Motorcycles_Parts_Accessories&hash=item4854a1fee5&vxp=mtr

The only thing you have to do is take the stator out of your engine, and install it in the new one. The engine will then be plug, and play. The whole job is under 3 hours for someone that has never done it before, and a good scooter mechanic can do the work in about 1/2 that time, including road test.

Post up if you need help, and someone here will walk you thru it all.

Have you actually done a GY6 swap into a Super 8? 

I ask because I read somewhere else where someone tried to put a GY6 into their Agility 125 and he said it wouldn't fit because the engine mount was located in such a way that it wouldn't mount up to the frame.

And although a Super 8 uses a GY6, it's their version of a GY6.  I've noticed subtle differences such as the position of the exhaust port, the ignition pick up coil is located at 5 o'clock instead of 12 o'clock on a standard GY6, uses a 12 pole stator, the CDI has 8 pins instead of 6 and the final drive gears are located withing a detachable housing where on a standard GY6 are located in the actual engine case. 

I've considered doing a GY6 swap because the performance parts out there will fit but all those differences I found make me think that a GY6 swap isn't going to be easy.

From the horses mouth.

Thanks for the link. 

I never knew this bit of info and is extremely helpful but the article really doesn't state which gap to use if your manual states a range for the spark plug gap like the Super 8 manual does.

Also don't go cheap, Dr. Pulley sliders are like $30 shipped for gy6. I would think with everything else stock 10g well rev wayyyy over the power band. If your happy with how it performs with your stock weights go for 13 out 14g Dr pulley s

maybe not 10 grams but I would probably go down to 11 grams because my Super 8 was super slow when it was stock.

I've since extensively modified my Transmission and am using 12 gram Dr. Pulleys and I still want to go down to 11 and possibly even a 10 gram weight.

Super 8 150 / Re: the 600 mile oil change
« on: July 16, 2014, 12:13:23 AM »
Tonight I continued my 600 mile maintenance with checking the air filter (luckily a burly neighbor came by to loosen the allen bolts on the passenger peg, because they must have been tightened by a gorilla).  The filter did not look dusty at all, which I hope is a good sign.   I did notice when I removed the cover it smelled a little like gasoline or oil.  Next will be my spark plug; I bought one of those iridium ones.  When you gap the plug, I notice there is a range; is it better to aim for the higher or lower number, or does it matter?

I would probably go with the smaller gap since the gap widens as the electrode wears out but if you don't like the feel of your ride, I'd pull the plug and re-gap it to the bigger gap.

You should be able to see the oil if you can get the right angle on it. I try to aim for the mid point on the stick.

With only a 0.95 qt oil sump, I feel every bit of oil counts since these are air cooled engines and the oil accounts for a good amount of that engine cooling.

Movie 150 / Re: Movie 150 Review
« on: July 16, 2014, 12:03:46 AM »
It's broken in already but haven't given it a genuine effort for a top speed run yet. Once I do, I'll definitely post the results.

Please do, I'm very curious.

I'm curious what the top speed of this Movie 150 is. I really like the look of this scooter and the big under seat storage is what all scooters should have.

But 90-95 kph is not that fast in my opinion. 

My Super 8 could do that and it doesn't have a 4-valve head.

I'm curious to see how fast you could get it up to after the engine has been broken-in.

On my Super 8, the full mark on the dipstick is when the oil is all the way up the dipstick hole.

I usually check the oil just by eyeing it since the oil is so far up the dipstick hole.

Super 8 150 / Re: Super 8 won't start. Need service manual
« on: July 14, 2014, 03:41:16 AM »
Hi fellas,

My super 8 150 won't start after the winter.  I think its cuz I didn't winterize it well; it cranks but wont start.  I have gotten another new battery but still the same.  I think I need to take the carb off and worst the gas tank off to clean them.  I will greatly appreciate if someone has the service manual and is willing to share it with me since I haven't work on super 8 at all.  PDF is fine. 

Sorry to start this forum by asking a favor.   ;)

Thanks in advance!

Before you start tearing anything apart, try starting your scooter without the gas cap on.

Super 8 150 / Re: Drive boss grinding
« on: July 12, 2014, 04:09:26 AM »
So I've heard of shaving a millimeter or two off the end of the drive boss to make sure the drive belt is using all of the variator thus giving you all the top speed that stock will give you. Yeah I know if I alter it ,it's not stock anymore. I wanted to order an extra one in case I eff it up. Then I can put the new one in and say, "enough of that WayneO." For confirmation it is part #22105 that I want to order right? Or should I just leave it alone and look elsewhere to mod?




This post is a little old but I'll give a response.

I suggest leaving the drive boss alone and just get a Dr. Pulley Variator.

It raises the "gear ratio" some what giving you a higher top speed but acceleration will suffer a bit unless you go down in pulley weights.

Installing a Dr. Pulley Variator raised my gear ratio enough for me to put off replacing my final drive gears until I install my bigger bore and piston.

If your Super 8 is completely stock, I suggest going to 10 or 11 gram weights.

The Super 8 comes stock with 13 grams and I found those to be too heavy for the stock clutch torque spring.  When my Super 8 was stock, it felt like it went into high gear really quickly and accelerating would be slow.

People 250 / Re: How is it supposed to feel at high speeds?
« on: July 05, 2014, 07:04:28 PM »
Check your tires carefully.

I bought a used 2009 SYM HD200 a few months ago.  It only had 1800 miles on it looked good overall and the tires still had a lot of tread so I never took a real good look at them.

The scooter ran fine without any problems but when I took it on the freeway, the handling felt a little spooky.  It was like the bike would move laterally on it's own without any input from me. 

I decided to inspect my tires one day because I was bored and I found that there was a crack that ran parallel with the bead and the crack was around the whole tire, on both sides.  My rear tire wasn't as bad but there was a big gouge in the sidewall.

I stopped riding the scooter and promptly ordered new tires and the problem went away.

In hindsight, I can't believe I risked my life like that.  My tire could have failed on me at 70 mph.

Super 8 150 / Re: problem when accelerating from a stop
« on: July 05, 2014, 06:44:43 PM »
Do you live at sea level or close to sea level?

If so, it might be due to the air/fuel mixture screw needing to be adjusted. 

Due to emissions standards, the Super 8s come from the factory with the air/fuel ratio on the low side.  I live close to the beach and when I first got my Super 8, it would hesitate to accelerate from a stop just as you're describing. 

I turned out the air/fuel mixture screw and this helped out the situation a lot.  The only problem is that the air/fuel mixture screw is under a metal cap that you have to drill out or if you're lucky, you'll be able to use a small flat head screwdriver and pry the cap off.  And then you'll find that the screw doesn't have a slot to insert a screwdriver so you'll have to use some really fine needle nose pliers to turn the screw counter-clockwise. 

Also,you might need to re-jet as well as the stock main jet is a tiny 103 size but I would try turning out the air/fuel screw first as it doesn't cost you anything to do.
