Super 8 / Polini high Speed - Kymco Super 8 4 stroke

« on: April 26, 2017, 08:42:34 AM »

I`m about to install this in my scooter but noticed that the drive boss i 39mm long compared to 38mm of the Kymco original drive boss. This I guess means that I will get 1mm less splines to use on the crankshaft. As I can see there is already a tight fit with the 38mm boss so I am worried that I will strip the splines when using the longer drive boss.

Can I use the Polini kit with my stock boss?

Super 8 / Kymco Super 8 50cc 4 stroke - grinding noise

« on: April 18, 2017, 07:17:37 AM »

Have had a rattling/grinding noise coming from the fan side of the engine since last week. Tore apart the fan side of the motor and found nothing that looked wrong. However, this is the sound I get when I turn the gears that are inside (see link below)

What could cause this sound? Could it be something with the starter clutch? I have noticed that the starter slips occasionally whichs means that I have to release the start button and press it again to get the starter to grip and turn the motor around.

Note, I have no play in the crankshaft either on the fan side or on the variator side so I doubt it could be the bearings. Only play I have is maybe .5mm back and forth but no play left and right.

Super 8 / Kymco Super 8 - 4stroke 50cc - 2008

Hi!

My Kymco Super 8 - 4stroke 50cc - 2008 model is topping out at about 32mph even after I have removed all the restrictions. Have I missed any restriction you think?

This is what I have done so far:

- Replaced the variator boss to a smooth one
- Added 6.5gram Dr Pulley weights
- Installed a brand new belt
- Change main jet to 86 (80 was original)

I have also checked and there is no lip in the rear pulley that is restricting anything (unfortunately). What else is a restriction on this bike?

Thanks!

PS. This bike is purchased in Europe so maybe there is a difference between the US and the European sold bikes....

Super 8 / Longest belt for Kymco Super 8

« on: August 24, 2016, 01:17:28 PM »

I have noticed that there are several belts in different lenghts that are advertised as suitable for the Super 8 50cc. I have seen lenghts from 728mm up to 743mm. Have anyone tried different lenghts and does it make any difference?

Super 8 / Kymco Super 8 - 4 stroke

« on: August 15, 2016, 01:51:05 PM »

Hi!

I just bought a 2009 Super 8 (4 stroke version) and I have removed the shoulder on the variator boss and I have also removed one of the purpole wires going into the CDI. By doing this I increased the top speed with roughly 7mph to 32mph. However, I would like the reach atleast 35mph. I noticed that the variator roller weights are pretty heavy (about 7 grams) Will I gain or loose top speed if changing to 5,5gram roller? I know that you usually loose top speed with lighter rollers but maybe the stock ones are just to heavy

Would be interesting to hear from someone who actually have experience with this scooter.

Thanks!
