Checked my new rotor again, Ohms between the two rings is 6.4. seems to me that it was less than that when I first installed it. Maybe 5.7 or so. Is this a sign that it's on it's way out??

    New Rotor

    just installed new Rotor from Ricks. 2nd one. first one failed after 20 miles. Installed an LED volt meter on handlebar so now at 3000 RPM it charges 14.3-14.4 volts. Is this a bit high? will it over charge my battery?

    Sustained RPM

    My bike is gear low. 17 tooth front and 36 Rear. That's stock for my 1984 SK Canadian model. So it revs quite high. What RPM do you guys like to cruise at. Is 5000 a bit high? Seems like it is to me. Pretty sure I'll have to get a 33 or 34 rear sprocket. Thanks everyone for the replies.

    1984 XS650 Instruments

    Please enlighten me. Is there some sort of light to warn of low oil pressure on my 1984 XS650 model SK? Or any thing to warn if battery is not charging? Will buy an aftermarket Volt meter since these bikes don't have a voltmeter gauge. What do you suggest for oil pressure warning device? Thanks.

    My 1984 XS650 SK Canadian model has mismatched mirrors. Did that year have round or rectangular mirrors. Also on my other bike (Harley) the mirrors have (objects are closer than they appear feature) that I really like since I get a bigger picture of what's behind. Any Yamaha mirrors available...
