Hello! Looking for some help.

Have an issue where my engine starts and idles great. As soon as i give it some gas to accelerate there is no movement. Engine has no issue stalling or anything. No movement on the tire. Took off case to inspect belt and everything looks good. I was able to see the clutch work and spin the case. Someone how it is not spinning the wheel. Any suggestions?

4k miles. Rear wheel has some play in it that i believe is more than normal. The play can be found by moving the whole wheel side to side. maybe about a quarter in or less or play.

You must have missed something in the transmission.

This sounds like the clutch is broken, or belt is worn, or gearbox or variator issue etc. Do you have any photos?

Berto,

I can take some pictures however i removed the case and ran the engine. Belt was in good condition. Gave it some gas and the belt spun fine and the clutch was opening and closing as it should. I have not removed the variator or clutch yet (waiting on a tool). Could it still be a belt or variator issue if the belt was spinning? Could the clutch still be broken even if i was able to see it expand and contract? Any help is appriciated!

With the clutch bell re-installed, does turning it also turn the rear wheel? If so, then the clutch shoes aren't making good contact with the bell, even if they do go out somewhat when spinning.

Just curious if you started the engine with the clutch bell off? If you did, play the lottery, you are one lucky person.

Jimc,

The clutch bell is installed, when i try to spin the clutch bell (engine off) it spins freely and does not spin the rear wheel. However when i spin the wheel it does spin the clutch bell. Is that what you were asking me to do?

Thanks

Something is broken or not fastened correctly - splines or gears.

If you put the nut back on the driven axle (no clutch bell this time) and turn the axle with it, does the rear wheel move? Do NOT start the engine...

Now might be a good time to check the oil level in the final drive.
Or maybe even drain it, and look for sparkly things....

When you turn the clutch bell, the rear wheel should rotate very slowly.
When you turn the rear wheel, the clutch bell should rotate quickly.

when I spin the axle it does not spin the wheel and has this rough grinding sound. But when I spin the wheel, the axel does move. Does this point to problem to the gears? Please let me know!

Yes, that's a problem with the gears - assuming the rear wheel is correctly mounted on the final axle splines. If you haven't touched that, it should be OK.

I have not touched the wheel but maybe the previous owner did. Would you suggest I remove the rear wheel and take a look into gear box next?

Did this ever work OK for you, or is it a recent purchase of a used bike?

All these details can make a big difference to the advice given - I've been assuming it's worked fine for you for some time and been regularly serviced...

I purchased 2 years ago and it was riding great up until this issue last week. I have put about 2000 miles on it. Only part I have serviced is the oil change, air filter and new fuel lines.

Have you ever checked the hub (final drive) oil?

with the clutch bell off, give the wheel a spin in both directions- does it move freely both ways? is it loud and crunchy in either direction?

in one direction, there will be a grinding sound as if something is is rubbing. this is normal, because the primary shaft is not torqued up, it floats in the case and the helical cut of the gears will move the shaft and the gear rubs on the case. it sounds like a low grinding sound.

let's see a shot of the clutch bell.

also, have you disassembled any of the drive pulley or variator?

I'm guessing that you've got something messed up in the clutch, but I wouldn't rule out something like a stripped 1/2 pulley, maybe a crank.

it's unlikely to be the gearbox itself. a *distant* possibility would be a drive shaft gear stripped from the axle. more likely would be stripped splines on the wheel or axle.

if you can let's see some pics of the drive, the bell, and the wheel mount.

Inside picture of the splines of the clutch bell first please - if you think they're OK we'll want pics of the splines of the final axle and inside the rear wheel.

I believe I found the issue, let me know your thoughts

After taking off the wheel you can see that the splines in the rim are completely worn. Assuming this happened because I noticed the wheel had play in it and it was loose. It was not hard to remove the rear wheel nut.

All pictures you requested are attached.

There's your answer - a new wheel is required. The axle nut should have had a castle cage over it and a cotter pin through the axle.
