Hi having a bit of an issue with my 2014 Kymco super 8, bought It new 5 days ago and have 280 miles on it I took the variator apart last night and put it back together the exact same way it came apart. But now it won't accelerate until I'm doing 5-10mph which can be dangerous in intersections and I'm screwed if I stop uphill any ideas what the problem might be?
-
Maybe you tightened the nut with the belt down by the spacer and the outer face is loose and didnt pull apart the driven pulley (rear pulley) to allow belt slack when tightening?
-
Sorry I don't understand what you mean
-
How do I pull apart the drive pulley?
-
Watch specifically from 4 to 6 minute mark in this video. When he grips and pulls the pulley to separate it in order to loosen the belt.
But watch all of it afterwards.

PART 2 INSTALL

That belt has to be loose and high on the variator when tightening the nut or it gets pinched when tightening the nut and you will cause damage if the variator nut comes loose while riding.
Before doing repairs etc, see if you can find something on youtube to guide you and look at the comments as sometimes these youtubers are not correct in their procedures.

Awesome I'll try that when I get home
-
Seems like it helped a little but it's still really slow till 5mph
-
Maybe use 8 gm Dr Pulley Sliders and a 1500 RPM contra spring.
But as with the other post, I'm just guessing. But it good to get that variator on properly as a start.
The scooter really needs a full derestriction to get good performance.

First scooter I've owned what's that spring and what does it do?

Had someone think it could be the carb what do you think?
-
It could be a number of things
-
Well I called the dealership and they're going to remove some of the epa Crap tomorrow
-
yea its under warranty. they should make it right
ask them if there is a smooth variator boss they can install if you dont have one already on.
-

Oh then yeah I don't have a smooth boss

when you say that it does not accelerate do you mean that it hesitates/wants to stall when you open the throttle if so i think the carb needle needs to be shimmed if that is a 2 stroke. does your bike have two bulbs that do not work at the headlight mine does and the light control module went out i think possibly from riding in the rain caused a short at the high low beam switch because the highbeam indicator was trying to light before that the lights would infrequently quit i then turned the key off to on while riding and it came back on. possibly a rubber cover over the high low switch would help if everybodys l c module goes bad in the rain. i put led lights where the bulbs were that did not work and wired them in to the black wire at the ignition key. at the light control plug behind the front cover take off the bottom panels too, i used a continuity tester a light lights when there is voltage to find the wires for hi low and power to it. i think the hot wire was white about the third wire on one side the other two wires were on the other side i think the second and third wire. i got a 35 amp on off on switch the one wire on one side feeds one of the two other wires for hi and low beam. only works when the hi low beam switch is at the low position pushing the switch to low from that position turns the headlight off momentairly until it is released when the bike is running. the leds work when the key is on.
