OK so recently my belt broke on my scooter. Before it would go all the way up to 1200 rpm. Now after putting a gates power link belt on I can't get it past 7500 rpm and it goes very slow. I removed the variator and the clutch to put the new belt on. The new belt is alot thicker that the old belt. I'm really confused and pretty bummed if anybody. would help it would be greatly appreciated.

What is happening is you are simply seeing the contrast between a brand new belt and a worn out belt. Worn out belts are thinner because the use of them grinds down the sides slowly, that's why drive belts have hardened walls. A thinner belt can climb higher and go lower in the variator and clutch, but will break as you already know. When you first get a new belt it needs to be broken in, give it a week and you should be speedin around again. |

But while riding not past 7500 |

But while riding not past 7500 engines will always produce less rpm's under a load... if you really think it is under performing then i would clean out the cvt. you may have to take apart the clutch. small fragments of a broken belt can jam the clutch and variator. |

Ok, a few things to look at... Did you get all the pieces cleaned out of the clutch? When a belt grenades, cords and
chunks get twisted, tangled and wound around all over the place.
Check, the weights are in the variator correctly. Sometimes they tumble when you loose a belt.
Did you purchase the correct belt for your bike?
When you put the new belt in, I usually put it in the clutch first, give a good tug to get the belt into that clutch pully so that there is a little slack when you slip it over the variator. That way, when you tighten it down, the belt is already up the groove a little and not at the bottom of the groove. It makes it much easier to get the variator face on all the way before you tighten the nut.
My money is on a flipped weight in the variator.

If you can reach 7500 rpms on a straight road , your doing good. There is a red line for a reason , and that is to warn you that if you reach that red line you better back off the throttle. Your engine will not last long especially if you are running near 12000 rpms. With my scoot , I tune my CVT so that I can hit 7500 rpms on a straight run and nearly 8000 downhill. I can imagine how high your engine temps were ! I bet you were really close to burning it up ! You might already have damage. As your belt wears , the rpms will rise , when this happens you will want to counter it with heavier roller weights to bring the rpms back down. Don't let the rpms keep rising on you. Also make sure you buy a good gates belt , not some cheapo , it will not last too long. |
