Just a few days ago, I heard it for the first time on my GT 200. When getting going from a red light or complete stop, there is this weird noise coming from the back...once the gears kick in completely, it goes away..Yesterday when riding two up, I heard it again...every time when we stopped at a red light and went on again, there was this ugly noise...could it be the belt that's suddenly loose? I had it just replaced with 4000 miles...am approaching the 7500 mile service...but would be odd to have to replace the belt every 3500 miles...or is this normal?
thanks!

Fan still on when bike is off?
I don't know about your noise but I have a noise and thought I'd add it to the thread to see if it's normal.

I turned off my GT on Saturday during our group ride and I felt some vibration, like it was still on. It was the air fan, we think. One of the guys in our group is a scooter dealer, though not Vespas, and that's what he thought. A few seconds later, whatever it was turned off. I guess it's like a Honda car we once had, that after you turn it off, the fan stays on and turns itself off a few minutes later to cool down. Anyone else notice this?

Hey OZ did the last fix work? I know you had some new stuff done, just wondering if it is working, Beale.

I think you're probably dead-on correct, it sounds like the cooling fan. It's temperature-activated, only on when necessary, and the scooter has to be pretty hot, too. You should be able to put your ear near the left air gill (same side as your horn button) and hear it whir when it's on.

So far! The entire mechanism was replaced - drum casing, clutch wheel, rollers, belt, blah blah blah. Fixed it by replacing the whole darned thing.

It's been good for about 700 miles since the last repair, which is far more than the previous issues. Darned good too because my warranty expired.

Can you describe the noise? Sounds to me (without hearing it, no pun intended) a lot like the clutch slip problem a few of us have had.

Clutch noise and slipping
I want to tell everyone about my clutch noise. My GT is an 05 and I didn't get any slippage or noise until nearly 7000 miles, so I cleaned out the clutch shoe dust, replaced the belt and eveything went back to normal.

Now I am at 11,600 miles. I occasionally get a shutter noise from the clutch perticularly when the engine and trans are cold. It seems to go away when everything warms up, and it happens intermitently, very strange. At 12,000 miles I am going to pull the housing again and replace the rollers and take a look at the clutch shoes. The slight shudder is not really a big deal and doesn't effect the performance much.

Has anybody tried the new Malossi / Polini- Delta / Speed clutch and bell housing. I have a new SIP catalog and they ar in there. I suspect this will solve all these clutch problems and improve performance.

They also sell an upgrade variator which boasts up to 30% better acceleration, too bad it cost so much to ship from Germany to the US.

Slipping Clutch
My '04 GT has a clutch that slips.

Symptoms: After 30mins of riding across London (I travel frequently from Greenwich to Hampstead) the transmission starts to make a sound not very dissimilar to a "waaaaaaah" noise if I pull off with moderate revs.

When I visit my parents in the countryside it is not a problem, presumably as less is asked of the clutch as the roads involve far less stop start riding.

This occurs after around 15 mins if I have a passenger on. A service guy at a dealer said it was down to dust from the clutch contaminating the friction material on the mating surfaces.

Presently it has not been so bad as to lose 'drive' altogether, until then I think I'm just going to put up with it. I can almost eliminate it by pulling off faster, but this is not preferable as I value the low fuel consumption.

Would setting up an email address to be ultimately forwarded to Piaggio for GT owners experiencing the problem be of any use?

we were having a barb-q in our backyard, about 95 degrees and humid.
(poor planning on mother nature's part). A buddy, who had been drinking, walked by the Dragster 180 and Samantha's GT, both use the same thermoswitch for the coolant fan, and as he walked by the dragster, the whirr of the fan came on, startling the drunk friend. Looking at the Dragster as he passed the GT, WHIRR the gt's fan came on, scaring the hell out of him. He now claims our bikes are out to get him.

From new my GT125 has made a vibrating noise from the rear as if the top box was rying to shake loose at about 10MPH. At lower and higher speeds it goes. It is much more noticeable when cold. The only time it is a problem is when filtering very slow moving London traffic when you are constantly changing speed betwen 5MPH and 15MPH and always seem to be moving through this vibration band. Other than that all accelelration is very smooth and vibration free.

finally found out what the noice was :-)
had my GT 200 in for service yesterday and the guys told me that the noise I had heard at times was some rear metal part (don't remember the name), where I had lost two screws...so it vibrated against the tire or something....oh well...glad it wasn't the clutch.

Apart from that all was fine - 7000 mi on the bike...and lots more to go

Cheers,
