Need assistance on buying a part.

[Dannykjm15909]

Hello I got a piaggio Zip 2 stroke 50cc. I'm looking at buying a new clutch. I already ordered a poling variator kit. But I'm confused on purchasing a clutch for my bike, malossi is the one I'm wanting but I'm not sure if I need to get a clutch bell because the clutch is on it's own.

Some of the others come with a kit but this malossi one don't will I need to buy clutch bell. Also I'm buying a new 19mm carb will I need to buy a intake manifold to ??.

I'd strongly advise against fitting all of the parts you just listed.

Basically guys I've bought a leo vince zx for my zip and installed the 5.1g rollers and blue springs that was supplied but it's lost all power I es doing 40mph before with a leo vince sp3. I'm just lost on what to do or where to go from here I don't wanna bore it out just yet want let it live a bit first.

I'd look at the jets first. You need to go up at least 10 on the standard size.

What was wrong with the machine before you started to upgrade, if anything?
Tinkering with these usually requires access to a wide range of differing weight rollers and then lots of experimenting.
This leaves most people with three options - to go back to what worked well beforehand, spent lots of money on parts you won't use or get a mate/professional to help out (on site).
There are no magic formulae, get the head/carb you want then experiment with rollers/belts, etc. Bang head repeatedly until it's just right, blow it up almost instantly then back to square one.
Good luck

Running fine before the installment doing 40 on the way to garage when I was getting it done. When I got it back it just got no power now and it's lost that loud zipp sound when the revs kick in. Think it might me the rollers and springs I put in that came with the exhaust.? It would wheelie off the line before.

Dannykjm15909, I advise you to put a post in the workshop section and ask about Cliff... only Cliff will get you more speed out of a Zip.

If Cliff can't be found, ask for his mate, Skip.

Best of luck with it and be sure to post updates

Leo Vince exhausts are meant to be just about the best 2 stroke ones now made. However you can't just bolt them on and expect to be the king of the peds. Carb settings, jets, timing, there are a myriad of adjustements needed to get things right.

Get them wrong and you will know about it quite quickly!

These threads do make me laugh. In a few months OP will be seventeen, why not save the money for a 125 and be a bit patient.

As others said, tuning a stroker is way more complicated that just bolting on some magical 'thing' to make it go faster, especially when by dint of your age you haven't got a clue about the theory or practice of that you're trying to do.

^^^ Weren't you ever young Andy?
I remember the futile hours spent stripping my Bantam trying to make it go more than 30 and it was a 125 that was supposed to go faster than that, with a gearbox, and I still had little joy!!!

The only way to learn is by tinkering but it's handy if you can find mates with Zip's and learn together, at least you can swap parts and get stoned together! Trial and error seems to apply best when using non standard bits on these scoots.

hi, I ride a Honda cbf 125 and I was just wondering is it worth buying a scorpion exhaust for it?

[andyscooter]

in short no

long answer my scorpion fell apart so no

and a zip wont do much more then 40mph in the real world without a hell of a lot spending on it and then it will need the engine stripped and rebuilt every 2500 miles to keep it running properly

and mallossi and polini are shite use stage 3 parts or leovince

19mm carb will need a new intake manifold. It also wont sort the problem you have.

The variator wont really do much as the bore is still standard.

The clutch, again, wont need to be done, as it 'wheelied' off the line before.

Malossi and Polini make good stuff, Stage '6' does also.

The Zip comes with a good gearbox as standard. The problem you have is most probably jetting related. Buy a box of jets, keep putting a bigger main jet in till it bogs out at full throttle then go back down a size and do a plug chop to check it.

Although it will probably be impossible to do any of this as the gearbox is set wrong.

So take it back to the garage and get them to sort it. Like said in the other thread.
