vento/zuma/jog what's the difference

[shayandaman]

Hey, I was wondering, if you have ever looked at a zuma crankshaft and a vento crankshaft or tried to swap parts like a variator, the zuma crank is smaller. Since they have different cranks, wouldnt that make them different engines? Also, what are MAIN differences between the vento, jog, and the zuma, as far as the motors go?

[smokin]

Ya I want to know too. I know the gearing is different on a zuma but am not sure about the jog and I've heard something about the crank being a little different aswell on the zumas. Maybe some other members know about the differences???

im going to let u in on a lil somthing smokin...a crank on a vento is way diffrent then a zuma...because i think shyan got a star from a zuma ..and NOP didnt fit way too small...so thats how i know but im pretty sure ryda said on some thread that jog on the other hand is the same as a vento motor...

SOME Ventos use the same size crank as Zumas, but MOST do not. ;no So, some parts can be inter-changed ;)

All of the scooters you mention above are called "Minerelli Horizontal" so yes, they are the same motor.

[smokin]

Got a question. In a zuma in the gear box how many gears are there lennox altogether? I know they are not the same but I want to know.

i was woundering...why does a zuma go so so slow stock...i mean we have a zuma that goes 40 stock...and a triton over hear doing 50.....i never got that

off the top of my head, I wanna say 5....my photographic memory might be wrong though :naught:

the Zuma is slow cause its so darn heavy! :confused:

i thought that they are around the same weight.....because a triton is around 207...a zuma weight around 190-210

[Lennox]

my bad, I thought you were refering to a ZIP :o

[shayandaman]

That is what i am wondering, the zuma and the triton weigh about the same AND they have the same motor..........so? Maybe its the rev limiter?

Rev limiter???whaaaaattttt...the only ones are in the pipe and the vair..is their more..maybe my scooter is still restricted and i dont know about it :confused:

[smokin]

Hondas are fine. Only on zumas theres a rev limiter to 8000.
How about those Jogs though we are forgetting about them.How do they differ?

[shayandaman]

Your mistakin, they have a rev limiter in their CDI which limits thier revs to 8000 rpms...................Lennox, you think this could be the reason why they are so slow?

[wideopen01]

Yours is fine only on zumas theres a rev limiter. How about those Jogs though we are forgetting about them.


And this so called revlimiter...do you have anyidea where it is located...did you say the the cdi....ohhh i know what ur talking about..thats the reeason why jered and lenix changed their cdi's gotcha

from what I've read on the web...arent ALL cvts 5 speed auto?.....................Maybe o-- Geely is an exception

We are talking about the lowering gears in the back of the tranny case next to the tire.

Cvts (constant variable transmission) are yes an automatic, but not 5 speed.
It is many many gears almost an almost uncoutable amount of different ratios depending on a few things rollers,rpm,and pulley sizes. I'll pm you with more info.

[Aviatrixie]

There are no discrete speeds (ratios) in a CVT. It's continuously variable, so in a sense it has an infinate number of "speeds" between it's lowest and highest ratios.

We use a hydraulic CVT called a Constant Speed Drive for the 115V/400 Hz 3 phase alternators on our jet engines to keep the generator speed constant throughout the speed range of the engine. Exact same principle, just a bit more high tech.

[smokin]

You must have missunderstood my post.

I said Uncountable number of ratios.

Which is the same as infinate, hence when you have an uncountable number of ratios you have just as many variable speeds so if you were to stay at the same rpm the ratio would not change because there would not be enough centrifugal force to push the rollers higher on the ramp plate.

Which in turn would not make the pulleys squeeze more.
Which means the ratio would not change therefore it is possible to calculate an exact ratio at a particular rpm as long as it remains a constant.

[XPS1210]

sounds about right...but you'd have to get to that speed and be able to monitor the tranny at the same time....

[florida derbi rocket]

Sorry folks..I'll lay lower on the boards and keep my mouth shut till I rebuild my scoot :(

[smokin]

You wouldn't have to monitor your tranny but you would have to monitor your rpms and speed.

You can dertimine what the gear ratio of your pulleys are as long as you know what gear ratio you have in the back and how big your tire is.

Which would be a good thing to know because you can see how much of a gear ratio increase you get at certain rpms with different roller weigths.

He is trying to say monitor it as in cheack your belt....rollers and what not...like my honda one time i was cheaking my rollers and the plastic around the rollers broke off...thats what he means..i understand what he is saying.

i know that the 2000+ jogs have a 2mm longer stroke and longer gears, and thats why they top out a 60mph stock.

Hello,
Newbie here. I am thinking about getting the BKM Jazz.

Is the Jazz and Jog engine exactly the same?? If so, what year Jog?? If its not then what are the differences??

Also if I can get a hold of a JDM Jog motor, will it just bolt on to the Jazz's frame??

[rydah]

if you are going to get a jazz then just use the engine thats in it. you will waste plenny money trying to get a jdm engine when you can just use that money for performance parts. i dont know if the engines are the same since the jazz is made in china and the jog is a minarelli engine.
