Looking to purchase kick start mod and wondering if you could still keep the electric start and battery. Will timing effect bike performance with timing change (cam mod). Any help will be greatrly appreciated.
I, personally, feel the kick starter should replace the e-starter. If you're not adding the kick starter to loose the weight of the e-starter, then you must feel your ATV needs a backup to the electric start.
Just about every electric start ATV on the planet doesn't have a kick start backup and I don't see why the YFZ450 should be regarded any differently. Just to name a few of the sport ATVs that can't have a kick starter: Warrior, Raptor, 300ex, 400ex, KXF400, LTz400.
