Hi,
I hope somebody can help me with a couple ??. I had just bought this Roketa new in February and still haven't ridden. Don't want to bore you with all the bull so I will try to say this as quick as I can. Got it and there was a rubbing noise from rear. Took it to a shop and got a hold of where I purchased it from. Has come down to Roketa putting the wrong drive shaft on when they built it. My question is how big of a job is it to replace the shaft. From the breakdown I've seen on this sight it doesn't look like it would be too hard to do. The reason I am asking is I don't want to get taken by this shop I took it to. I don't know them. They said they worked on Roketas but I really have my doubts. I even had to show them a few things which scared me. I found out that they have a person that works there that said he has worked on Roketas. Any way, this guy was talking about it's a really big job and it would probably cost me more in labor for him to fix it then what I paid for it. I'll bring it home and do it myself or blow the damn thing up before I let this guy have it. So, can anybody out there tell me approximately how many labor hours this job should take and just how hard it would be to do. Thanks in advance for any and all help you can give me.

Sincerely,
fnshnegrl

Hi Leslie. I think the first thing to do is a removal. That is get the scoot out of the scooter shop. There are no drive shafts in these scoots. They use a CVT which is a belt drive in combination with a variator and centrifugal clutch. A slight rubbing noise is not unusual because of light contact of the disc brakes with the rotor. This is normal. You have to check to make sure that the tire is not rubbing anywhere. If you can hear a rubbing sound with the engine off and on the center stand, then it is most likely the brake pads. A small amount of drag is normal. The wheel should turn with some resistance by hand. The only other place for a sound while spinning the tire with the engine off is the transmission. There is an axle and some gears with bearings involved. Make sure the transmission is full of gear oil. A small amount of sound from the transmission is also normal. Sounds from the rear brakes or the transmission should not be loud enough to be heard while driving the scoot.

If rubbing sounds occur only when driving the scoot under its own power, then the sound is coming from the CVT (no drive shaft).

If Roketa has indeed installed an incorrect part which causes the problem, they may require proof from a dealer before shipping a new part, but I don't think they will be shipping a drive shaft.

Let us know whats going on and the Scooter Doc clinic will be here for you.

I sorry I may be using the wrong terminology. It is the shaft that the rear wheel goes on to. The rubbing noise was the caliper bracket was rubbing against the nut heads that are on the disc of the rear wheel. With the rear wheel off hthere is alot of play in it. They said and that it could either be the wrong wheel or the wrong shaft. Roketa supervisor said that the shaft would fix the problem. Does that sound about right? Sorry I do not know the right terminology.

HI..on the center stand.....check to see if the rear wheel is loose...side to side play....there is a nut on the right side ...which attaches the wheel to the clutch....make sure it is tight...what engine...244 or 257....most shops do not work on China scoots....keep going....it is worth the time and effort...we have great forum members to help you....enjoy the ride...

It's the 257 engine. Yes there is side to side play and the nut is tight, Spacer is not missing. That was one of the first things we checked before taking to that shop.

The shop made measurements for Roketa and took pictures. He told them since he didn't know if the rear hub or the splines on the engine were wrong . Roketa said they were going to ship the output shaft as they felt that would fix the problem. My problem is I don't know how hard that repair is and what would be a fair labor hour. Is it something we can do ourselves? Thanks again for all your time.

I suppose it depends on where the play is. If the play is in the wheel sliding back and forth on the shaft, adding another spacer or washer should take up the slack. If the play is in the shaft, there are bigger problems inside the CVT. The wheel slides onto the shaft and the the splines inside the wheel line up with the splines on the shaft.

Move the wheel and see if the shaft is moving or the wheel is moving.

Yeah, it's actually very easy to take the rear wheel off once you get started. There's a bearing in the swing arm that may even be causing the noise.
You'll need an impact wrench, and just start with the muffler, then the brake, then the shock, then the swing arm, then the wheel.

Then start the engine and see if it still makes the noise with the wheel off.
