I just bought a new to me '99 WR 400. I was wondering if anyone has hooked up any type of tach or small oil or water temp gauge? If not how do you tell if the bike is running hot? or cool? I know on Harleys they make a dipstick with a temp gauge in it, I did not know if anyone made such an item for the WR. I thought the tach might just be cool to have on the bike. Thanks for any info.
