Frizman, i agree with you and Mr. Firemouth and LynnEdwards, the everyday joe knows very little about this kind of stuff. i agree that it's used as a lure to sell us "high performance" items when it may/may not be compatible. one of the things about electrical items, you usually cannot return them for a refund. bummer, i know, right! I thank the Good Lord for this website and the assets that teach us everyday about ATVs and the ins/outs of the business. thanks to all.

 

has anyone found a after market CDI UNIT that does work yet
i have 2/4 pin for a 250cc zong

 

I will be putting a performance cdi on a 150 GIO LAMBO Later this week if all goes well.. we will see what it does.. as I also have 12 g rollers and the next size jet for the carb... but I will do one thig at a time.. to see what really works... I will post when I get done.. the cdi is from SCRAPPY DOGS ON EBAY,.. cost was $12.00 plus shipping

 

i realy doubt that it will work
But i have been told that you need to change coil and something else ???

it would be nice to know exactly and where to buy the items for all atvs

 

Well, I don't have a dyno but I do have a GPS unit.
With the factory parts the bike did 21mph wide open and after the 30mm carb, new coil wire, and Casoli CDI it now runs 33mph wide open.

The bike is faster on top end, not really any stronger on the bottom end.
It is a Kazuma 150.

I would say it was worth it. Now if I can only find an air cleaner to fit the 30mm carb!

 

pod filter your looking for is 46mm you can get 1 on ebay

also i think the reason you got that extra speed is because you changed to the 30mm carb

 

Yeah the carb helped for sure!
But the CDI I bought was defective and I ran the slower speed with the standard 5 pin CDI, then I put the new (2nd) Casoli CDI on and got way higher RPMs.

 

what was the highest rpm with the standard carb?
what was the highest rpm with the new carb?
what then was the rpm with the 2nd cdi ?
what then was the highest rpm with the last cdi?

 

Standard carb was junk, never ran.
rpm with new carb ran @ 4800
rpm with new carb and new CDI runs @ 6600

Replacing a CDI alone won't give big gains, but will help.
Replacing CDI, Coil wire, opening spark plug gap slightly, and getting a bigger carb will help noticeably. A good pipe will help too.

One thing is for sure on this 150 Kazuma. It was fairly quick for a 150 when I got it and after the mods it runs more like a new 150 should. Remember this bike is a 2003 model. The motor and trans has probably seen better days. LOL
