the rev limiter is built into the CDI, you can get a CDI without the limiter on ebay.

Replace your CDI
what is effect raicing cdi to yamaha vegaforce
on 5occ - 150cc gy6 qmb or qmj engines the rev limiter is part of the cdi programming.
You can not remove it, but you can change out the CDI box. http://www.magnumtuning.com/en/detail/revolution-pro-atv-speed-rev-limiter-cdi-box/john-deere/gator-xuv620efi/atv
yes it can be tested with a cdi tester!!! that even as a part number
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.
try the yamaha seca store.
