yeah your mechanic is an idiot, here is what you do... get a tune for it, run a wet shot, run NGK TR-6 plugs, and have fun, you will be safe on a 100-125...the motor does not run any hotter from nitrous, it can go lean if you are stupid and don't know how to hook up a kit, just follow the directions....i think your mechanic is an older fellow and doesn't know how much better the motors are built
i second that! we just talked about this yesturday, right, virgil?
