VESPA GTS 250 AND 2013 MODELS

hello 2013 model vespa gts 250. While coming to the end of a long journey, a sound that did not exist before started to appear. This noise only happens when driving at a certain speed. When driving at 70 to 80 km/h, there is a rubbing sound, like the sound of a caterpillar beetle. once the variator bowl was changed, the sound decreased and ended. It started again after 4 months and I changed a variator bowl again, it decreased again, but now it came again. This problem made me tired of driving a Vespa. no master could find the reason. there is also a repulsive sound that looks like a wheeze when driving at 10 km and 40 km speed at takeoff, as if the variator has dispersed. This sound stops when it reaches 41 km. It goes very well up to 80 and this time at 80 km speed, the sound I mentioned above comes out. I took it to 7 technical service centers in my country. they are all incompetent masters. I'm going to buy a camera to add videos soon. but the related sound is similar to this sound at 80 km. I don't think it will come from anywhere else. because the sound stopped when the variator bowl was changed 2 times. it means there is a problem with the variator.

Welcome to MV, demefe!

Was the YouTube clip supposed to be of the sound your variator is making? All I hear is crickets.

It's difficult to make a proper diagnosis of sounds via a text description even in the best of circumstances. When you add a language barrier to the equation, it's even harder.

I'm not entirely sure what kind of problem you're describing in the first part of your post, However, this second part -- the part of your description quoted above, and specifically at takeoff -- this sounds like a clutch problem, not a variator problem. The GT200 was especially susceptible to this problem, but I don't think the GTS is completely immune to it. When it happens, it sounds like a metal chair being dragged across a hard floor, and the clutch fails to engage.

If this is actually a clutch problem, then the solution is to de-glaze the clutch shoes. Some light sanding with 100-grit sandpaper should do the trick. It's also worth cleaning out the inside of the clutch bell, and possibly roughing up the inside surface with some scotch-brite pads.

Yes you are right. This was an example for the sound that came out. I will buy a camera for the sound coming out of the engine and record the sound on that camera. thank you

typing yes unfortunately does not work. Vespa masters in my country know nothing. I will immediately investigate the clutch problem you mentioned.

Here's a wiki article on the clutch subject, accumulated from many years of this issue from many people:

Hello Vespa loving people. My variator problem is solved. It was solved simply. How Does? First of all, the problem was this: 3 years ago, when I was driving at 80 km, suddenly a noise started to come. this sound is like the sound of a caterpillar beetle:( the variator bowl was changed, the sound stopped. It started again after 100 km. I never thought to change the front variator mounts. Unfortunately, the master did not think of it this sound is only heard when driving at 80 km speed. 70 or 90 km It doesn't come off while driving at speed. My advice to you: if you have a problem with the variator, change the straps temporarily. This may be 80 percent of the reason. Right now, my engine just screams a lot, it makes a lot of noise. Unfortunately, this time I'm obsessed with it

I recognise there may be translation difficulties - but what is meant by 'front variator mounts' and then the 'straps' that are mentioned?

I wrote it without realizing it. I am writing with translate. my english is very bad. but when the front variator mounts were replaced, the rattle-like sound disappeared. But the engine makes a lot of noise. As if there is an exhaust problem or I did not fill the transmission oil or engine oil correctly. This is the first time I've done this myself. When you give gas, there is a violent acceleration. It's like I have a rally engine

Sounds like you're still having problems, yes? Can you please post another video showing the sound and location?

variator mounts changed. I don't know how "baga" translates, but I uploaded a photo. The sound between 10 - 40 km and it only travels at 80 km speed, the other sound is completely silent. Thank God. But now it's a different problem. the engine is running at too much volume. I will check the transmission oil. Variator cleaning is very important. Constant cleaning is required.

The very loud engine may just be the exhaust 'gasket' (graphite collar) between the downpipe and the silencer ('muffler') that has given up. They are consumables - always keep a spare!

Ah, those would be "rollers"

Agree on checking the exhaust. Sometimes possible to feel a leak (don't touch if hot!), also check torque on the fastening bolt....but don't overtighten! Assuming the graphite collar is worn, it's not all that hard to change....plenty of information and help here..
