Re: RZV500R chain guard Tire Information Sticker

Hi, I've had a look through our workshop manual and a spare parts book and there doesn't seem to be any information
or stickers listed about this decal. I've only seen them on the RZV500.
Cheers Ron.

Re: Carb Nozzles and a Parts List Mystery

both nozzels are OO different hole sizes. N8 and OO have 475 on them, are the holes in the nozzels to mix air with the fuel
and does the air jet control this.
