Anybody tried changing the clutch spring?

[GSeX]

I'm considering getting a stiffer clutch (torque) spring for my chinese 50cc scooter to help it get up the hills better.. its falling out of the power band. has anybody here tried this or would recommend for/against?

Think you will find its falling out of horses.
Maybe a bigger piston and barrel would be better.

im assuming its centrifugal clutch. Which means youre gna be putting weaker springs in to throw out faster.
I advise against.
As said. Get rid of the fag scoot. Get a real bike.

Do what the Taiwanese do and grind out the inside of the flywheel :yes: We had a Thai helper at our shop who dealt to the local postie's hyosung scooter :blink: wee fucker went a lot better afterwards

Interesting suggestion LOL. I'm buying a 'real bike' for my performance needs but I swear this fag scooter can go better than 20 up a hill.. It does 80 on a flat. It's not the clutch springs btw it's the torque spring. Hmm could big bore it...

I think the kits are cheap to do it.

They are cheap, but i'd want to be sure it won't make the scooter impossible to start or run rough. up-jetting can be tricky to balance

Read some of the overseas scooter forums. Once you start playing around with modifications, you either finish up with a short lived hand grenade, or are forever re adjusting, resetting, replacing, rollers, jets, needles, air intakes, exhaust etc.

The headaches just aren't worth the minimal increased performance.

Go on a diet.........

Try roughing up the clutch. Over time it can wear smooth. Or even wear thinner. Scuff it with low grit sand paper for something the clutch can bite into. Be conscious of what direction you scuff it... 90 degrees to the direction it rotates.

Yes I replaced mine and it did make a difference. Might be on a scooter by scooter basis though

the clutch springs that i replaced were a lot stiffer it was a real bitch
so the clutch would engage at a much higher RPM better for launching at the lights
the down side is you flat spot your rollers much quicker as they tend to be sitting at the same spot for longer

yes and don't unless they are stuffed. If they were never good to begin with chances are the rest of the bike/scooter will follow suit.
