Description

This is the ultimate EVI for GY6/QMJ157 150cc and QMB139 50cc systems. If your scooter feels held back by the stock rev limiter or weak spark, this CDI/coil combo is the fix — stronger spark, better throttle response, and more of the pow...

This company is more of a media company that sells parts on the side. Good luck trying to get any custumer service from them, oh and they erase reviews, like real reviews not like this. Like when their EFI doesnt perform and you cant contact custumer service becuase they are too busy filming for youtube so they rather just delete your review and pretend you dont exist. Too bad i dont think i can post pictures here. They deleted all the ones i posted on the website. I guess i can try posting on youtube, maybe they'll see it there.

Worked great alot better than the cheap CDIs bought elsewhere, i had to disconnect the ignition coil and reconnect it in order to get it passed the gas tank but was fairly easy definitely recommend getting it
