Why dosnt this make sense?  By  Deleted (Read 1,741 times)

It doesnt make sense because its wrong

As a general rule of thumb

Lighter Weights= Faster Acceleration with Less top speed

Heavier weights= Slower Acceleration with Higher top speed

Of course this is not always true. For instance if you take and put 10g rollers in a stock 49cc it will have poor acceleration and a low top speed because the gear ratio climbs too quickly and the weak motor cannot propel the scoot any faster and will just bog down.

If you want better acceleration you need to go lighter. As far as the slider weight i have heard that The sliders are weighed in at one gram under weight because a slider performs similar to a roller one gram above its actual weight. Not sure if its true but thats what i've heard,

You need a dyno chart for your engine to answer that question. I would shoot for about 1000 rpms more than current...

For faster take off try 1k , 1.5k or 2k clutch springs . These engage at their rated RPM that much above stock springs , like a stall convertor in a car with an auto tranny . Gearing has a lot to do with it too . A buddy has a 2T Elite and its instantly takes off like a forklift but peaks at 20 MPH then slows down where my Magnum has never been a fast take off with the 90cc variator and 13 inch wheels vs 10s but has way more midrange and top end .

My TaoTao 4T had 8 gram rollers and I went down to 5 g rollers since it very hilly here , take off and uphill was better with the same top end just more RPMs . My 2T had 6 gram rollers , I tried 4g was too light as it sounded like it would over rev on takeoff and lost top end as it had a RPM restriction when stock . I mixed them up to equal 5 grams and liked it . With a BBK and pipe 5g was too light as I could redline uphill so I tried 8g Dr Pulley sliders with Hoca 1.5k clutch springs and a Hoca BB torque spring base . I bought a 1.5k torque spring but could not compress it with the BB spring base so I put the stock back in as it never had any problems going uphill . Well takeoff is slower as I push off with my feet when going up a grade from a standing still , but has great power from 25 up to top speed but I can still hit 9k up many hills with a rolling start . This is a 2T that now hits 10,500 . So heavy weights and short gears are not the answer as I will have to get lighter sliders and taller gears as it guzzles up gas with it screaming compared to when it was stock .

I also replaced the 12.2 rollers with 12 Dr Pulley sliders and wow it has a better acceleration at all times with a 5 MPH top end gain . My scooter dealer with a scooter with the same engine as mine uses 14g sliders and would hit 75 MPH too just not get there as fast . I love out running cars from takeoff and while cruising on my CFMoto Echarm . I have had 5 people follow me into a gas station and offer to buy it from me . Sliders push the belt out more than rollers , last longer , are quiet as rollers rattle when they develop flat spots from wear as mine started to at 5,500 miles . I replaced the belt at 12k and the variator glides as they had some wear but the sliders were barely worn . With the Hoca BB torque spring and sliders in my 2T it really sounds like I have a car auto tranny that has many gears compared to before and it also prevents the torque spring from binding ..

You may opt to get a roller kit with several weights to test as .5g will make a diff . These are softer than normal and intended for testing rather than long term use like this www.enviromoto.ecrater.com/p/14177743/prima-roller-weight-kit-16-x-13 find a weight that works best then get 1g lighter in sliders .

The 1.5clutch springs seem to help but you may like 1k springs as 2k may have you popping wheelies and wear out the belt faster

but the t3 i had ran great with a 1.5k torque spring with 10 gram weights koso variator i weigh 195 pounds

I have a T3 that had 6 gr stock rollers...cant imagine trying 10 gr!

i recommend 6 gram sliders with a koso variator on a stock scoot at least for you
