200x_basket: ive always thought about a 350x headlite on my R but never got as far as even measureing it up, is it a perfect fit or you have to modify it a lil?:lala:

i would run one number hotter then it calls for this is what i do with my bike and it works out pretty good. i was told not to run too hot though, so be carefull i would only drop a nuber. and resistor plugs are just as good as non resistor so it dosent matter. outta all my time running trikes, bikes, and sleds i cant tell the diffrence and the resistor offers the protection of radio signals wich can help you out. also cell phone signals and GPS units!
