Does anyone use the one on eBay/Amazon/AliExpress or is it junk?

Many sellers all selling what looks like the same Chinese one.

For the rear driven pulley / clutch assy I'll use 2 large bolts to lock it together to remove / install the outer nut on the shaft

On my BV I use a homemade copy of the Bikemaster tool, and another homemade tool for the clutch. When I got my Vespa I splurged on the proper Buzetti tools. Their variator tool works better than my homemade one but I see not much difference with the clutch tool. About anything that fits the holes in the clutch should work equally well, including the tool made from a bent U-bolt that you can find here on the forum.

I have this tool and do use it. It is not perfect, but OK both for 50cc, 250cc and 400/500cc.

Thanks.
That top tool?

It's $9 shipped on eBay so for that $ it's a no brainier.

What are the short comings with it? Is it strong enough for ocassional use? It will probably on get used every few years.

Indeed on my MP3 I bought that Buzzetti tool as it's unique & not just an adjustable generic pin holder tool. It worked great when I changed out my belt loops last year, essential to do it really.

Will do if I buy it.
My concern is are those pins strong enough for a retorque or will they bend like cheese. Some Chinese tools are strong and others are cheese metal.

No doubt that Bikemaster tool is made in China too.

The pins won't bend but the arms may. My homemade variator holder is made of 1" x 1/4" steel bar stock. My first version used thinner bars and it did twist and bend. YMMV.

Makes sense, thanks.

To remove the nut I think I'll just hit it with my impact lithium tool.
Robot mentions that vs needing to hold the variator to remove the nut.

If that flys then the holding tool only comes into play when I torque a new nut back on. That's a slower more deliberate process of applying pressure.

What he said. Make a template out of a piece of aluminum foil or stiff cardboard. Drill holes in a piece of 1x6 (I used a scrap of fence board) and put a couple of bolts through the holes and nuts to hold them stiff. Here's one I made for my Silverwing. Same principle for the Vespa.

Gosh - I just use a $0.50 U-bolt, appropriately bent.

Oh, clutch nut, sorry. I had one of the pictured 'scissor' tools back in the UK - it wouldn't cope with either the clutch or the variator on any of my bikes. Useless, IMHO.

For the variator, shell out for the appropriate tool - you'll be using it enough that it pays for itself very rapidly.

I was going to buy one of those, but I used an electric impact wrench instead from Harbor Freight that I already had. Its way easier with an impact wrench. I will probably still buy one but will carry it under my seat to use only for emergencies on the side of the road. Given the cost for one of these universal holders, why would anyone buy the factory tool?

Because the 'universal holders' don't fit *anything* Piaggio.

How do you get accurate torque when you re-install the assembly?

So from this thread are links to that same tool above, a copy of a Honda tool maybe as stated?

It's the exact same tool sold everywhere.

https://www.amazon.com/YunShuo-Variator-Remover-Puller-Scooter/dp/B071FG7BR2/ref=sr_1_9?ie=UTF8&qid=1506200031&sr=8-9&keywords=variator+tool

Also in thread is the home made variator tool using 1/4" pins
That is said to work.
1/4" = 6.35mm
Chinese tool has 7mm pins (look at link above).
Dam close even if you need to grind down that Chinese tool pin ever so slightly.

So how does this Chinese tool not work almost the same home made tool does JimC?
What size are the pin holes on the variator?
And how far apart?

Am I missing something here?

Because the 'universal holders' don't fit *anything* Piaggio.
Confused why not? Care to elaborate vs just say buy the $100 tool that I may once every 4-5 years.

Pins the wrong size?
Pins too short?
Arms don't spread wide enough to fit the variator?
Tool is in the way to retorque the nut?

Did you actually try on a BV?
My MP3 uses a different way of holding, bolt on a Buzzetti tool, but it sure looks like the BV uses pin holes.

As for the clutch that just needs two screwdrivers / bolts / rods etc that fit in there well and that locks up and is ready to accept torque to the nut.

Thanks!

Use a torque wrench to quickly remove the variator and driven pulley / clutch bolt. No big deal shops do that all the time to spin off bolts.

BUT you need some kind of holding tool and a torque wrench to reinstall the assy. Proper torque is essential and a impact gun will never achieve that going back on.

Pin sizes. No mention of length but it possible to approximate.

Any else care to explain why that tool's small pin will not fit in those 2 holes and hold that part well enough to torque a bolt on it?
Even if I need to grind them ever so smaller to fit.


Am all ears???

Thanks I get that idea, just make some with bolts that fit those pin holes spacing and size and has an access hole in middle so you can torque the variator bolt down.

My apologies - that is the first Piaggio variator I've ever seen that can take the pins on that tool.

Are there any others apart from the BV350?

Dam close even if you need to grind down that Chinese tool pin ever so slightly.
7mm = 0.275

Even though I haven't measured the hole, 1/4"pin is fairly tight. I'd bet cash money you'll be grinding the tool(or you could drill the hole).

My home made tool has been used on all my bikes close to 20 times. Seems to me that this is a lot of effort put in on something so simple.

My homemade tool uses 1/4" bolts. They fit perfectly. Note -- the unthreaded part of the bolt is used for the pin. Saw the hex head off a 3" to 4" bolt, use two nuts on the threaded end to hold it to the "arm", one nut on each side.

Not alot of effort, just verifying that I'm looking at this the right way with holes in that part and a pin tool needed. Doing my homework before I pull this apart for the first time ever. Was confused by JimC's comment, but it sounds like this model is unique.

Going to buy that tool and will grind it slightly if needed.
Less effort than trying to build my own tool imo.

Thanks

Yeah, you can buy one made in China for less than the cost of the materials to build your own.

I made this one from scraps lying around 10 years ago. It fits the clutch and variator on a number of bikes from 50cc to 200cc. I added the aluminum a couple of years ago because the bolts were starting to wobble. I have a much bigger version I made for my burgman.

Nice that works. Thanks

I'm ordering that one from above (cheapest eBay supplier as it's all the same tool) and I'll report back if I need to grind down those small pins ever so slightly to fit. It's a tool I can then compactly fold up and stash away until I need it again in 12000 miles.

Doubt I'd ever own another scooter past my MP3 400 (which I have a tool) and this BV350, my wife's scooter. If anything I may sell my MP3 and buy another BV as it's more fun to ride. Scooters are a city only thing for me no endless shifting, otherwise I'd rather be on a moto up in the mountain roads riding BDRs or G1s.

I stated above that the pieces of the variator tool were 1" x 1/4". They're really 3/4" x 3/16".
The pictures include a clutch tool. Not very elegant but it works. It could have been simpler.
