Besides the bronze bushing has anyone found a better replacement for the stock bushing?

That's pretty much what one of our members had done and gone back to the graphite/asbestos OEM gasket.

There was mention of an inexpensive gasket (relatively speaking) via Aprilla and tried to locate online but cannot get in US...if anyone knows of an alternative...it would be great informaion to have.

From the right sources (not it seems any in the US!) the OEM collar is cheap enough - and if looked after (as much as brake-pad wear say) - is no problem to have on the bike. Just like rear brake pads, think of changing it at about the 12,000 mile mark. It beats the shit out of the potential aggro with one-piece pipes.

What do you consider "cheap enough"?
Of 4 internet sites, only 1 has them in stock.
Scooterwest, if they were in stock, sells them for $30. + shipping.
AF1 has them for $49 including shipping.

I wouldn't pay more than GBP10 - USD15 - so just like the belts, you are being shafted!

Yamaha makes a graphite exhaust bushing for their 2 piece exhausts - i don't know the price or model number but I'm sure a good Yamaha parts person can help you out. It does the job just fine and may be easier to get your hands on.

Jim...yes...we are...the Piaggio OEM gasket is priced rather high and the Aprilla is just not available (either via dealer or online in the US). So you have to opt to go outside the US...I tried to secure a quote and the shipping is rather expensive.

Hence, in the US I believe our only option is to purchase OEM thru your Dealer or a Piaggio online supplier @ the ~ $30 + shipping.

The only other option (from a pirated post) is someone who fabricated their own (emergency) gasket...I believe Jim may have provided this link...wouldn't recommend it as a routine gasket...it was a fix...although nothing was mentioned about replacing with OEM gasket...hmmm

You know Ive had a few VW rabbits/golfs and they had a cone shaped gasket that was much harder than the Vespa exhaust. I can understand the brass bushing not having enough give to handle the vibration, but I think the vibration is what screws up the OEM bushing in the first place. I wish I could find the same material that the auto people use. Anyone out there have any clue? If I had a solid piece of that material I could have it machined here at work.

I bought one from a fellow MV member but I haven't picked it up yet. When I get it I'll take it to our purchasing agent and see if he can find something similar. He's great at finding oddball stuff.

is this the Yamaha gasket?
Does anyone know if this is the Yamaha gasket?

3YF-14714-00-00 used on several Yamaha bikes one in particular is the TW125/200, a 2010 bike – they sell for < $13.00 retail.

Came up with the number using the Athena catalogue on the Louis Fun Company site, crossed it to Yamaha parts numbers.

Personally, I bailed and got a Leo Vince pipe

No trouble since
and I've been delighted to finally have a low maintenance exhaust
(No excessive rust, no cracking & vaporizing graphite gaskets... bliss! )

I have the yamaha gasket and it works fine - not sure of exect model number but if it fits a TW125 it 'should' be the right size.
My mech uses the Yamaha one as it is cheaper and apparently longer lasting than the Piaggio ones. I'm sure the Yamaha one will be easier to get your hands on.

if the yamaha gasket will work for sure on a GTS250/300, please let us know. I think the OEM gasket is still the way I go. When I use one I order one. Have two on hand. But the price is crazy.

Stopped by our local Yamaha dealer and the TW125 model is European only.
They didn't have a crossover to a US model bike.

We will likely be offering a less expensive OEM gasket in the near future. Maybe 2-3 weeks.

O.K. Max now you're talking...as you can tell by prior post the European market has cost effective alternatives and we can't get it in the U.S. So we'll see what you come up with. Please make sure to post as soon as you get them in stock.

I recommend and support local Vespa dealers, or mail order Vespa dealers – in my case, this time, I need the part next week – this is what I found:
Because I need to replace the wife’s rear tire I purchased a spare gasket from Yamaha today, just in case I break the OEM – the part won’t arrive until next week, around the same time the new tire arrives.
If it is the correct gasket, never even seen the OEM gasket, the part number is 3YF-14714-00-00, $16.25 out the door. The TW125 and TW200 use the same part its item 11. The TW200 is a 2010 USA model. Yamaha has been using the gasket since the late 70’s, and the part number has been superseded, or is in its 4th generation, the above is the current part number – the parts guy at the Yamaha dealer told me this.

Your other option would be to remove the exhaust pipe at the at the header...check this excellent video tutorial by micbergsma...

Looks like to much work to remove the exhaust. I would rather use a new muffler gasket.

Yep...and that's the option that can be used to discoonect the exhaust pipe.
However, please be careful and I'm going to have to defer to those who have opted to go this route to chime in on the foot pounds torque in resecuring the clamp...I believe it's 10 to 13 ft lbs (?).

GTS exhaust gasket – they look the same
I didn’t use the new gasket because the OEM wasn’t damaged when I separated the header from the muffler and putting it back together - the Yamaha gaskets looks to be the same dimension and material – I’m saving the new gasket for when I need it in the future.
I do support Vespa and vendors, but, for this item Piaggio/Vespa and the vendors need to step up and charge a fair price; Yamaha can get the gasket for less than $20.00 to their customers, I would expect similar pricing for the same item from Piaggio/Vespa.

Louis fun company list the dimensions in their catalog: http://www.louis.de/_40f7f31844cacc975497b5bfc88b9a1e7c/
Follow it through and you can cross it to Yamaha and their bikes that use the part, then cross to Yamaha part numbers.

I have changed my bushing three time in the life so far on my bike. I'm pretty good at assembling things but I never get a 100% seal. Is it just me?

Would someone post the dimensions - OD, ID and length of a stock exhaust bushing?
Do the GT200, GTS250 and GTS300 all use the same bushing?
How about the GT125?

Dimensions for the pipe on the GT125, GT200 are the same - and probably the same for GTS 250/300 - The workshop i go to has been using this Yamaha gasket on all Piaggios for a long while - and the gasket is working fine on my GT125.

Ive seen Athena make a replacement, which you might be able to source in the US easily... its a shame you guys get stung with the prices so much, that gasket is only £8.32 in the UK and that genuine yamaha one is a massive 1p cheaper



The piaggio one though, has much bigger dealer margin, so more scope for discounts

The gaskets dimensions are listed by piaggio as being..

Inner Bore Diameter 32mm
Outer Bore Diameter 38.5mm
Length 30mm

Found it here...ordered 2.

http://www.boats.net/parts/detail/yamaha/Y-1JK-14714-00-00.html

$9.42...plus shipping.....$25.79 delivered for the pair.

I've got a fresh unused gasket that can be compared so I will let the board know if they are the correct size when they arrive.

Muffler Bearing ??
This thread reminds me of the "muffler bearing"/"blinker fluid" joke

Thanks for the info GTdespatchcourier & cheekythomas, here is a summary.
Yamaha makes a very similar exhaust/muffler bushing/bearing/gasket.
The Vespa bushing measures - ID - 32mm, OD - 38.5mm, Length - 30mm.
The Yamaha bushing measures - ID - 31.75mm, OD - 37.6mm, Length - 30 mm.
The current Yamaha part no. 3YF-14714-00-00 supersedes 1JK-14714-00-00 which supersedes 2G2-14714-00-00.
The Yamaha bushing is used on the TW200 (2010), XS650 (79-80), XJ700N (takes 4) motorcycles and hundreds of other models.
Yamaha makes an incredible number of models.
Many Yamaha ATVs use a 5ND-E4714-00-00 that is replaced by the 3YF-14714-00-00.
No wonder Yamaha can make them cheap, they use these in 1000s of vehicles.
The Yamaha 3YF-14714-00-00 part is available from many online suppliers in the US from $9-$12 + shipping (which can vary a lot).
Our local Vespa dealer doesn't stock the part because the GT200 is discontinued.

I updated my previous post with the dimensions.

I wish that this thread had started two weeks ago. My GT was in a Yamaha dealership for 10 days waiting for the Vespa gasket (and rear brake line). They probably could have gotten the Yamaha part quickly, but I still would have had to wait for the brake line. I had two people ordering the Vespa gasket and bought from both. Now I have a spare that will be traveling with me, along with the proper tools, on all of my long trips. I paid $27.00 for the gasket from the local source.

~ $30.00 that's about right...Max @ Motorsport mentioned possible access to a less expensive alternative and I believe Glasseye ordered a pair of Yamaha gaskets and will update on dimensions as well R&T Babick provided same (?).

Want to know if anyone installed and what were the results?

If works then I'll go ahead and order the Yamaha gasket or if Max comes up with an alternative...I already have a OEM spare already and in no rush.

By the way, there is a Exhaust Expanded that is available via Motorsport that you may want to consider when attempting to install the gasket and exhaust pipe as a "mated" set...in prior post there was mention that having the gasket mated properly with the inner wall of the exhaust pipe and having "mated set" slightly flared makes the install somewhat easier. Which would prevent damage to the pristine exhaust gasket requiring ordering another $30.00 gasket...didn't we just come from there?

The Yamaha gasket works fine.

Had to sand the header pipe a bit to get it on, but the header pipe was a bit rusty & needed it anyway. Nice tight fit.

The exhaust side clamp needed to be cranked down a bit more as this gasket is smaller in OD by, say, a millimeter but it tightened up nicely. No exhaust leaks, though I only ran it for a few minutes before putting the PM pipe back on.

Only down side I can see is when you go back to the stock gasket you will need to spread the clamping area of the exhaust pipe back to the larger diameter....not a big deal.

Quality of the Yamaha gasket is very nice, perhaps better than the Piaggio.

Great find....
