CVT Slipping?

[kmonroe99]

I was riding early this AM, doing about 45 on smooth road, and all of a sudden it was like the CVT, belts, or drive shaft were slipping. I started to slow down to pull over and it quit. When I accelerated back up, it slipped/jerked for just a little and then quit.

Any ideas?

So it wasnt shifting gears?

How many miles do you have on it? What was you doing just before it started? We will need more info! With the cvt set up there is all kinds of things that could happen.

Hard to say....

possible there is something that is making it slip some foreign substance. Run it up and down and see if it clears up and if not you would have to run it by the dealer and have them get into it.... :banghead:

It doesn't have gears......:dontknow:

 

[kmonroe99]

No, I was traveling at a steady speed.

100 miles. I was traveling at a steady speed on smooth road and it was like it slipped engagement or something.

100 miles is not much, if it was mine ,I would ride it some more say 500 miles and if it keeps doing it or gets worse I would get it to the dealer and have it checked out. You have two clutches and a belt that don't like oil water dirt and what not on them. And if the weights a springs in them get bound up they will not shift and work the way there suppose to, hence your slipping action.

Check all the fluid levels, there seems to have been a few delivered with low fluid levels.

There are no finite gears with a CVT.

I was wondering myself why my RPMs were running 4400 RPM at only 30 MPH.

Was the road surface wet or sandy, did the rear tire loose grip? I'm wondering if it could have been the Nanny kicking in

As mentioned there are weights also known to some as sliders that dictate the position of the clutch. These will move at a certain RPM due to centrifugal force. I have a Yamaha T-Max maxi scooter and I can feel when these weights move. Possible that one or more of these were sticking or partially hanging up during this transition. That would cause what you are describing. I think I would put some more miles on it and keep tabs at what speed/RPM this occurs and if it goes away with some more miles put on the bike.

If you are sure it is slipping I would not ride it more. I'd contact the dealer, give them the facts of the case and get them to look at it. Continuing to ride may not only leave you stranded. But cause greater damage, if there is something wrong.

But the "nanny" lowers RPMs rather than raise them.

I would strongly suggest that you take it to your dealer and have a tech or someone knowledgeable to evaluate it after a test ride. Don't know your experience level with a belt driven CVT clutch on one of many so powered vehicles.

Excellent point, I out thought myself.

Maybe like the ski doo's brp shipped it with shipping oil all over the clutches .With the doo's we have to wash the belt and clean up the mess that the dealer was to doo.

A CVT tranny like the one in the Ryker ie a standard ATV CVT tranny, it is typically designed to keep the engine at the peak torque RPM. They don't really shift to a low RPM when going slow. The tranny shives (pullys) in the Ryker are controlled by the centrifugal force applied to fly weights which is a function of Both the motor RPM and the drive system RPM (speed of the vehicle). The CVT trannies in autos and bikes like the Suzuki Bergman Scooter and the Aprilia Mana 850cc Motorcycle, the Pully widths are electronically controlled thus enabling a low motor RPM at slow speeds.

It's a new vehicle. Without a doubt, I would take it in and let the dealer have a look at it. I am not one to be working on a vehicle that is under warranty unless there is something that needs to be done to get it off the road and into a safe location. Service is one thing, but having to diagnose a problem on a new vehicle should not be your job.

Yes, my Piaggio MP3 500 trike was the same way with its CVT transmission.
