Post Stimulating the wisconsin economy with scooter upgrades
This forum has provided gresat info to improve my recent purchases
For my daughter my wife vinos and a zuma for myself .
2004 vinos
Goals make them just a little quicker and closer to 40mph .

Spent the last month derestricting the variators on both vinos and derestricted the exhaust . Was running lean had to use mikuni jets had to buy quite a range the flow on the stock tk 14 is much different then the mikuni .I would estimate the Tk 64 main jet is closer in flow rate to a mikuni 70 then a mikuni 67.5 . Based on plug chops and how the engines were running wide open .
I also have moved the needle clip down to run just a little richer .
By having 2 vinos I have been able to tune 1 and then bring the other one closer .
Stock with restrictions they barely hit 30 by gps .
As of today with carb up jetting and derestrictions 38 by gps .
My next addition to the Vinos will be cht gauges to monitor cylinder tempatures.
To make them easier for the ladies to monitor health as they are riding.

2004 Zuma 41 gps on no wind day .
Quicker the wifes vino smokes me off the line .
Would like top end to be over 45

Have left stock so far .
Looking at sport cast iron bbk project possibly for the Winter
From what i have read that will give me acceleration but top end wont really change .
Looking to upgrade pipe for the top end increase.
Might try this first .
Leo Vince TT ,Technigas Next R are choices for pipes that don't rev to the moon .

Looking for advice on bbk and pipes plan on using stock airbox and carb
I have already ordered the TK jets 82 84 and 86 . Backordered per my Yamaha dealer .

The wife Loves my new hobby.
