Front numberplate/Finned aluminum thingy

Is that finned aluminum thingy on the left side of the frame opposite the 'black box' the rectifier? If so - can I remove that as well? Thanks

You should also order the YZF hub spacer and seal. This will allow you to take of the odometer drive to reduce unsprung weight.
86TT225, 98CR80, 99WR, WR timing, throttle stop trimmed, air box lid removed, White Bros head pipe, silencer and air filter. Odometer and headlight removed. Moose hand and mud guards.

hey harry, .."The thingy you refer to would be a voltage regulator since the system is AC. "
The system is A.C. ?? Call me ignorant, but Alternating Current on a internal combustion motor? Why would there be a need for negative voltages? I've been riding street for a bunch of years and the WR is my first dirt ride (that I want to mention) and I have never heard of Alternating Current in any manuals. They always talk Direct Current or D.C. The only AC I've head of is found on Gold Wings.. ala... Air Conditioning. Is it possible you've confused a voltage rectifier (changes A.C. to D.C. ) with a voltage regulator (limits amplitude of voltage)
call me confuzzed...

The electric power on the WR comes from the rotation of the magnets around the stator windings. This develops an AC voltage. Its frequency and voltage depend on how fast it is spinning and the load it sees.
On the WR all they are doing with this voltage is running light bulbs. The lightbulbs don't care if they get AC or DC power.
To simplify the system, they didn't bother to rectify the AC, but they do need to regulate it to keep the bulbs from brightening (and maybe failing) and dimming as the motor is revved.
On most bikes there is other stuff there that needs DC. That's why this AC stuff is not as common.

ya learn something every day. I understand the AC from the spinning rotor It's the couple decades of street riding that I am basing my experience on.. and well, I had always dealt with DC on my street beasts.
I appreciate the help. This board has been great. Since my purchase less than a month ago, I have put the 13 tooth sprocket on the front (mountain/foothill riding) and re-jetted for altitude and I would not have done either of those without this place's input.
