    GS425 Electronic Ignition Upgrade Questions

    Hello,
    I am wondering if anyone know of a source or has any experience with an electronic ignition upgrade to replace the points (contact breaker) & condesner in a gs425? Does Boyer make a kit, does anyone know thier web site address?

    I have installed my GS425 engine in my Sport ATV and am getting ready to rune it for as much power as I can get out of her.
    Here is pictures of the project

    A conversion from points to electronic ignition will not increase power. It will decrease maintenance. If your only reason for the change is to increase HP, dont waste your money.

      I wanted the elctronic Ignition mainly due to less maint. I understand I will not get any more power from the engine with an electronic breaker system.

        Check into the newer GS500E, I believe it has flat slides and electronic ignition. The engine is pretty much a 425 with a different valve cover. The 1982 GS400EZ does not have mechanical advance and I have heard of people switching them to a dyna and mechanical advance.

          I got a Electronic Ignition kit from Newtronic Systems LTD, for my GS425. It is a really nice kit and I am going to write a full review of it for my website. It is a plug in unit that works with the factory ignition coils. Very nice setup including evertthing that you need to install.

          Here is a link to Newtronic Systems LTD:

          With their SU-3 Contactless Ignition Kit i will never mess with the points again.

            hey there i have been looking at your website for the past couple weeks...i have been watchin for updates because i am tackling the same project 400 twin in four wheeler....lately i cant get to your website it says forbidden and cant be displayed....have you closed it or blocked it to people temporarily or somthin?

            Anyways a quick question on your four wheeler u had to moce the sprocket out i think it was 1.5 inches? and you had to put a retainer bearing....on mine it literally has to move only 3 8ths which mean when its lined up the sprcokets jus on the end on the transmission shaft...i was for sure i wouldnt have to make a retainer beraing butim not sure could you please tell me if it sounds like id need to or it would be pointless.
