Variator and Belt problem  By  viciousharp (Read 4,052 times)

But when you do that the dang thing revs up over 4000 rpms on a cold start!

You should simply slide it off and slide it on...How about a video from another ange to see if theres any side to side wobble.

Those allow the plates to separate allowing the rollers to open it. Thats an issue. You can buy those little pieces. Id replace them.

Sometimes because of the heat created the Variator Plate which you are talking about sticks to the Crankshaft. Reason is the Heat Expands the Crankshaft and it tightens up inside the hole of the Plate.

But when cold the Variator Plate should just slip right onto the crankshaft.

I noticed that at IDLE the Belt is down about 1/2 inch in the CLUTCH PULLEY, that is probably why the belt is slapping around. The Contra Spring is weak and not putting enough pressure on the belt allowing the belt to drop down and not strong enough to keep it up near the edge of the Clutch Pulley Plates.

Since the Belt is all the way down in the Variator and Some down in the Clutch Pulley you have some Slack in the belt and it will act as if the belt is to big and slap around.

The OEM contra springs are usually rated at 700-800 so putting on a 1000 rated contra spring will not actually help you on the hills as far as weights to handle the hills good you want lighter weights. You need to find out what your current weights weigh they are probably to heavy and lower your rpms which you need on the hills.
So if you do not have a small gram digital scale take the variator off and take a weight to the post office and have them weigh it then we can work from there. Also do you have a tach on the scoot and if so what is your current RPMS at top end speed and or around 50mph and 60mph. I would bet going up hills your RPMS are dropping and your speed then drops to much.
The best setup you want is say hit the bottom of the hill at say 50mph and going up the hill you do not lose rpms just mph. And let me say this you should have more throttle so if the mph are dropping to much you can crank up the throttle for more rpms.

Heavier weights make the Variator squeeze more and therefore push the belt up higher on the variator which in turn creates a bigger wheel turning a smaller wheel when the belt is down in the clutch pulley.

BUT there is a catch, Heavier weights will also bring down your rpms so TOO heavy of weights you may lose to many rpms and may cause you to lose top end. So you have to find the weights that will give you good rpms and at the same time have the belt climb as high as it can with the matching rpms and weights.

So it is a trial and error finding the right set of weights which will give you what you want and every motor produces different hp so that comes into play as well.
