vespa owners: belt compliaton thread

🇮🇹💦 Of the Loin /

so i know how we all hate running the multivars and having shitty belts.

well here is some help, people please post your success stories as well

stock grande : 4L410 works

malossi multivar w/yellow spring: Malossi part # 617223.

4L400 works sorta of on this setup, but the malossi belt is needed.

Re: vespa owners: belt compliaton thread

I am running the Malossi 617223 on my Grande as well - with multivar, but WITHOUT the yellow spring in the clutch. I am eventually going to get the big yellow spring installed and the little clutch springs installed, but I need to buy the tool that holds the clutch so that you can loosen the nut.

Anyway, the belt is working fine for me with my current setup.

who hates running the multivar? if you hate it, it's because you fail at setting it up right. i love it way more than my polini variator.

i hated it until i got the right belt!

Re: vespa owners: belt compliaton thread

on vespa-ciao.nl it's heavily recommended with the multivar and yellow spring setup. is anyone running the red spring?

Re: vespa owners: belt compliaton thread

The yellow spring is a must if your engine is hopped up much at all. Without it it'll surge when you accelerate. SO much better after I put it in there. I also switched to the Malossi belt cause I don't think the 4L410 was letting it open quite all the way. No complaints with the Malossi so far.

i want to try the green or purple spring with some heavy weights, the heavy weights are super easy to get, a lot easier than the light ones.

Re: vespa owners: belt compliaton thread

the polini weights?

Re: vespa owners: belt compliaton thread

sorry... springs

Re: vespa owners: belt compliaton thread

heah i think that's what he means, the ones treats has. should be comparable to the malossi yellow and red.

Re: vespa owners: belt compliaton thread

I compensated for the multivar/belt slippage problems by hitting the belt with a little belt dressing. That allowed it to grip just enough to start it and then I could run my bike. It's not a long term fix, but it'll do for now. The malossi belt seems too narrow and too long to work well. Maybe mine is just worn out.

Re: vespa owners: belt compliaton thread

the malossi belt just seems too long. it works great.

Re: vespa owners: belt compliaton thread

I'm currently using the 4L410 on my Bravo with the Malossi Multivar. I had to open the slots for the engine mounting though.

Re: vespa owners: belt compliaton thread

i used a dayco belt i got from angelo massimino made in italy. it slipped a bit and made starting hard. screeching during acceleration. the malossi belt from treats is much grippier for me...though the non-oval shape (due to packaging) gives it a funny spinning-laundry-with-unbalanced-load sound during acceleration. but this has gone away as i've used it more. with this belt i can start with 1 pedal and it doesn't screech nearly as much as other belt. btw, i have about 8 belts, most of them new that will fit....if anyone needs one, send an email...

Re: vespa owners: belt compliaton thread

it's super easy & cheap to make one of these tools.

stop by the hardware store, and go to the section with hinges. there should be some rectangular plates with holes in them. get 2, a longer one and a shorter one. also, pick up 3 bolts (i think 8mm work best) and 3 nuts. bolt the brackets together in a y shape, and put bolts in the holes in the bracket at the tips of the y. yay, cheap a super cheap clutch tool.

Re: vespa owners: belt compliaton thread

Awesome tip,...thanks!

Re: vespa owners: belt compliaton thread

Bravo = carquest belt 6841.

put on multivar, pulled engine all the way forward, belt slips the same as stock belt. slip = can't start with stock spring, only starts occasionally with yellow spring.

pulled engine all the way back, put on belt 6840 (1 inch shorter), belt doesn't slip, but can't fully variate up on the cheeks. I need to dremel the mounting holes a little forward to run the 6841 (but then pedals will hit the estoril pipe silencer) or backwards to use the 6840 to full potential.

Re: vespa owners: belt compliaton thread

no, i meant the malossi springs. they have 6 colors of them, yellow, red, green, purple, blue and white, in that order of stiffness, i think.

Re: vespa owners: belt compliaton thread

ᴛᴇʀʀʏ ᴅᴇᴀɴ /

oh, actually, now that i look, yellow and red are the only ones that fit the stock clutch/pulley system, sorry. i was thinking of the malossi springs for the clutch/pulley system i was wanting to adapt to my ciao. i'm a tard sometimes.

Re: vespa owners: belt compliaton thread

ᴛᴇʀʀʏ ᴅᴇᴀɴ /

also, the malossi belts are a bit long. the reason for that is most tuners over the pond run the larger variated pulley in the back, that you can't even get here in the states.

it's not a huge difference, but it's enough. if you elongate your motor mount holes about a quarter inch and slide the motor forward, they will work just fine.

this is on a ciao, btw. i heard that if you run the ciao malossi belt on a si or grande, they will fit proper.. but i haven't tried it, so do so at your own risk.

Re: vespa owners: belt compliaton thread

Have you tried the Malossi 617223 that a bunch of us are running? The place I bought it from claims that it is actually made for the bravo.

My Grande starts SUPER easily with that belt (stock spring currently). I pretty much just need to walk it a few steps and it fires right up.

If you haven't tried it, it might be worth the $25.

Re: vespa owners: belt compliaton thread

bumping an old thread...

other than the malossi belt, what other belts are you ciao runners using?

Re: vespa owners: belt compliaton thread

I should specify variated ciao runners...

Re: vespa owners: belt compliaton thread

bump

Re: vespa owners: belt compliaton thread

I've tried 4 or 5 different belts and I cant find one that works right. The Malossi works the best except for the slippage issues. The belts zippy has work almost as well and don't slip as badly. I ordered a bunch of 100mm rear pulleys. They should solve the slippage problems for good. I'll have them in a couple of weeks.

Re: vespa owners: belt compliaton thread

i have a 100mm belt and I still get slippage...

Can someone describe the "cardboard trick?" Pictures would be appreciated...

Re: vespa owners: belt compliaton thread

take a piece of cardboard, cut it into a belt shape, put on instead of malossi belt. works better if you've got the yellow malossi spring i hear, also, make sure it's corrugated, it's the cardboard equivalent of a toothed belt...but seriously

Re: vespa owners: belt compliaton thread

what?

Re: vespa owners: belt compliaton thread

I am going to put my multivar in this week. On a mostly stock engine, the stock spring should be cool right? The yellow spring is going to be too stiff, or am I mistaken?

Re: vespa owners: belt compliaton thread

with the stock set up you won't need that yellow spring.

Today I solved my slippage starting issues. First off, my malossi belt (which is the best for the variated ciao when new) was pretty beat up. So it wasn't grabbing like it normally does. Resorted to using my belt (the one around my waist) wrapping it tightly around the variator and pull starting it. WORKED LIKE A CHARM! I seriously recommend this method to anyone that has problems starting their bike.

I can take photos if anyone is interested in seeing how this is done...but I'm guessing that most get the picture.
