dirtrebel, thanks. Now this puts the yz back into the mix. Do you know if it is possible to add a street legal kit, its hard to get a definite answer on some forums I read that there is no way of upgrading the stator and that it uses all the power for the fuel pump and injection.
it definently doesnt use all the power for pump and injection. A street legal kit is easy, once you have a power source tapped off the capacitor, you can hook up whatever you want. A led tail / brake light only uses a few watts, and a small headlight pulls 35 watts or less if you go with led. I have a cyclops 630 led light for snowbiking. It came with a plug and play harness to take power from the capacitor. you unplug the capacitor then insert a nice plug and then plug the existing harness back in its really slick! I'm sure cyclops could sell you just the plug. The power then goes to a handlebar switch and you can wire up anything you want. As far as 100% street legal with high and low beam and all that might be pushing it, but for a working headlight and tail / brake light its no problem, if you keep it to like 40-50 watts you will be fine. Some say the bike uses the most juice at startup so having added electronics off at that time might be a good idea, but mine starts fine with the light on. I was looking for the exact spec but never found it however I did find several posts on forums stating output north of 110 watts.
