Title: Super 8 2t top speed
Post by: aaron8 on August 05, 2014, 12:28:38 AM
Alright guys I'm looking for someone that sells final drive gears for the S8 2t

When we derestrict our scooters we are getting them to go 40-42 (on the speedo)

Removing exhaust washer and all emissions
Removing intake washer
Installing drive boss
And #90 jet

Now we have installed a few 70cc kits and it gives it a lot more low end grunt, but the top speed stays the same maybe goes up to 45-47

So is anyone making final drive gears for these bikes?

What are you doing exactly that allows a 90 main jet to be used without it running too rich? Are you opening up the air screw or doing something to get more air in the carb ?

I'm at a fairly easy 40 MPH (only the flats) with blind pipe/EGR Pipe cutoff and weld, #85 jet, and smooth boss. I did open up the airscrew. I don't think my exhaust has a washer restriction but I have a 2T.

Also, thanks for making this forum active again.

Link for that setup. I just want to look at it. Not ready for a new carb upgrade but real close to considering one.

I think the exhaust is holding you back.  70cc BBK's still running OEM exhaust?, anyone running Tecnigas pipe?

What year is you S8?  2 strokes after about 2005 are heavily restricted for EPA rules and don't run as well as earlier engines.  Same engine, still capable of running great, just needs a few more mods.  I have 2005 People 50 2Tand runs 50mph with only mods: cdi destricted, 85 main jet, the OEM exhaust doesn't have any restrictions and works great.  I think your S8 50 2T has the same engine, so should be able to go a lot faster IMO.

I am looking to buy a used 2013 S8 50 2T, so I am interested in your issues.

I think there was something diff about the 2005 People's carb-manifold that gave it more power than the Super-8. Im not really clear on what it was as I think both carbs were 16mm.

The people 50 before 2007 came with 18mm carb and after they were 16mm. It's a good upgrade to the newer 2t to switch to the old style.

Then thats like a nice clean upgrade. Let me see if I can can get my seasonal job back and I'll look into doing that People upgrade to the Super 8. I thought I looked at an old pre 2007 people's spec sheet and saw 16" somewhere.  I downloaded the wron manual.

What I see here http://www.bikez.com/motorcycles/kymco_people_s_50_2006.php (http://www.bikez.com/motorcycles/kymco_people_s_50_2006.php) is the 2006 People has 3.72 HP vs the 2013 Super 8 at 1.50 HP. Thats quite a bit more power.

I think a pre-2007 People carb and minafold is the way to go if your not doing a BBK, an exhaust with an expansion chamber and open air filter and are sticking to a basic de-restricted exhaust.
