You need 14 /42 gears
scootertronics doesnt come through for you you can always order from somewhere else.
You need a wider range of jets no matter what kit you get to make sure your safe it is more critical with the Athena .
The Athena or malossi and silent pro would put you in the upper 40's by themselves the gears would put you over 50 mph .
The stock air box does not to be replaced it works fabulously till you get to full race level .

Hello and thanks for all of the good information. I lurked so long, I ended up deciding to join the board and upgrade my 2002 Zuma. I’ve attached a list of what I ordered and also ordered a Yasuni R. I figured this might be a good thread to pick some knowledge up on the Malossi cast and Yasuni R, but feel free to tell me to start my own. I’ve played with pocket bikes and golf carts, now scooters. My scooter has very low miles, under 1000. I’m looking to get it to be a reliable, peppy daily driver in the 50+ mph range. I’ve been told that this should be achievable with the stock carb,just maybe less torque than with a larger carb. I realize that I may not use the yellow contra spring, the clutch spring kit, and that the 4.1 gram rollers may be too light. I figured use 3 of them with 3 of the 7 gram rollers that come with the Variator to get in the 5.5 range. I have tons of questions!!! Where should I start the build / what would be a good build order? Do i need to pick up a few pilot jet sizes? Which spark plug NGK BR8HS or BR9HS? Does anyone premix or add oil to the fuel tank with their mods? Are yo guys running temp gauges and tachs? Is the Yasuni R really loud? Break in procedures? Any tips, suggestions, PMs or advice is appreciated. I don't want to hijack the OPs build thread, just seems like this is similar to my build. Thanks  |

It would be easier for people to help. The kit should come with all the gaskets and a small end bearing included. You might have to adjust the height to get the ports right. I would order a tuning kit for the rollers. At least to start with. |

When you get your parts like aerox said start a build thread so we can help you alot of your questions I cover in my thread .
You bought a great relaible peppy combo that would push 50 plus any expansion pipe requires carb and cvt tuning to run right be patient there .
Where should I start the build / what would be a good build order?
Go slow one part at a time so you can retrace your steps .
Pipe first Jet it rich and work your way down if you make a tuning mistake air leak or under jettedyou were going to replace that cylinder any ways .
Spend some time dialing in the cvt you will need some weights in the 5.25 to 5.75 range for your combo a 4 7 combo is sub optimal. You will need the stiffer end of your clutch springs
Enjoy it for a couple tanks of gas or a couple weeks this way you will have it dialed in and realize how much a pipe wakes scoot up .
Then swap on your bbk kit The carb and cvt settings will carry over you will pick up more power from top to bottom
Do i need to pick up a few pilot jet sizes? This is one size up order from yamaha dealer vino pilot jet 5BM-14353-23-00
Which spark plug NGK BR8HS or BR9HS? I prefer the 9 for this combo
Does anyone premix or add oil to the fuel tank with their mods? Stock pump works for me on any build like this
Are yo guys running temp gauges and tachs? Temp gauge is a must have for safety keep below 350 and watch for temp spikes a tach is real nice for tuning and are nice to have
Is the Yasuni R really loud? Loud and proud it will wake the neighbors They can here me coming from a block away
Break in procedures? I am in the warm it up real good and then ride it like you stole it varying rpms for the first 300 miles

The biggest reasons to start with the pipe is you will make errors in tuning and Pipes are what cause the most extreme changes in carb and cvt.
And there is the fun factor of methodically tuning and feeling the results .
The malossi powerband matches real well with the yasuni
If you have a tach you will find set it so it hits around 9000 rpms gives great power .
Clutch springs you will want to have them stiff enough so that when you hit the throttle you jump off the line and move with power if you roll slow for 20 feet and the get power you are not stiff enough.
Carb with the mikuni start at 100 and work your way down the 100 should just run gurgly when you take off and go wide open .
Work your way down from there when it stops being gurgly You are within a jet or so.
Track top speed and take the biggest jet that gives you best top speed .
Setting the needle work your way down till you get the best throttle response if 2 position feel close take the richer one .

Thanks for the good advice. I was able to cancel the yellow contra spring and 4.1g sliders, and add the clutch and variator tools instead. For some reason they said that the wrist pin is not part of the kit, which is weird because I see it in many others pictures. The pipe will be here tomorrow, while none of the other stuff has shipped yet, so I will get the primary jet and roller tuning kit, tach, and temp gauge ordered.. It’s good to know that the carb and tranny tuning should carry over, because I was hoping to get the pipe and try tuning the carb first, and then the transmission. I was thinking that would keep all of the tuning revs and errors off of the new cylinder.

The variator tool and clutch tool really make lif easier and keep you from making a mistake with a impact.
The wrist pin does not come with that kit so yes you need to order one .
16 x 13 rollers is what you need for the price of a tuning kit you could buy 2 different size between 5 and 5.8 and be in great shape with the yasuni.
It is a has a very wide power band to get in the middle of mid 8s to low 9s you feel the power band and those weights will get you there with the white contra .
The yasuni is fun on a 50 cc cylinder it will push you into upper 40's by itself since it is turning over 1000 rpms over the stock pipe
Stock pipe is done low 8k rpms The Yasuni R will push the stock cylinder low 9s .
When you pair it with the malossi cylinder you will push to mid to high 9s with it .

I'm only finding 5 and 5.5 in roller weights...are you finding the other increments like 5.8, or are you modifying to the odd increments?

Each manufacturer uses their is weights. Naraku do 5.8g in 16X13.

Swapped in new front brake pads . Bled the brakes big improvement The rear s are still good Took in a new pipe in trade tecnigas silent pro decided to swap on the zuma to see how it performs . from top to bottom wild lion on the vino then tecnigas silent pro ,tecnigas next r ,yasuni r . The yasuni is so much thicker in the belly than the next r The wild lion has a tapered and longer belly than silent pro  |

Swapped on the silent pro .
Kept the yasiuni r trans set up just to see what it was like .
5.5 gram sliders malossi delta stiffest setting with red springs
On the yasuni R I hit 10,000 to 10,100 at peak rpm the variator jumps to 8800 when I hit throttle and clutch engages above 6k rpms .
With the silent pro I hit 9600 rpms at the peak and shifts at 8500 rpm .
These weights might be as light as I can run .
Noticeable difference in power and operating temps She is running 20 degrees cooler and is less snappy
I am going to do a quick tune on the trans .
