Plug Resistor Removal

Has anyone removed the spark plug lead cap resistor on their 650R? Its supposed to give a better/hotter spark

Just wondered if anyone has tried it and if so is there any difference?

I could swear that when I went to do the resistor mod I found out that the 650r didn't have a resistor. I did the mod on my xr400 - didn't notice any performance improvement, but removed something that could fail (even though very rarely).
