Generally the electronic ignition module limits the rpm
Hi performance modules are available without limiter.
the rev limiter is built into the CDI, you can get a CDI without the limiter on ebay.
on 5occ - 150cc gy6 qmb or qmj engines the rev limiter is part of the cdi programming.
In the battery box. you will see it unplug it
Get the wiring diagram for your bike. I downloaded a great tank gy6 service manual that matched both my 50cc 4-stroke tank and baja scooters. I found CDI modules had a yellow and green wire going to something called speed selectable unit... I assumed a rev limiter. I diconneted the wires to it first. The bike didnt run.Then I tried connecting the green and yellow wires together, bypassing the rev limiter, and it worked great, so i did it to both bikes.
CDI box
it has a governor or rev limiter which is there so you don't blow the engine up and the minibike is probably topped out on top speed at 70 anyways
replace the stock CDI with a performance (orange or blue) CDI, make sure you get the right one, some are AC and some are DC.
Yes you can get a rev limiter. You can buy them from Scooter Attack dot com.
The rev limiter is part of the computer programming.
no rev limiter on 98 model
The rev limiter is part of the engine computer programming. The computer would need reprogrammed to change the rev limiter.
The rev limiter makes it so it wont over rev and the bike doesent blow up
