Tach and RPM's

I am wondering how many rpm's that others are running at certain speeds. I am wondering if I am running with higher then others. At 25mph and 35mph and 45mph, how many rpm's are you running and in what gear?

Also, my tach has always been a little bit jumpy but lastnight it was bouncing all over the place and very erratic. Is the tach going bad, or maybe a fuse problem or something else causing it by chance?

I don't pay too much attention to the tach at the lower speeds but mine registers about 3500 [email protected] and about [email protected], [email protected] I have the stock size tires on both front and rear.

A jumpy tach could be casued by several things, all of them electrical.
Places to check.. R/R, coil, ignition switch and even the kickstand switch. Might want to check these areas and clean and repack the connections with dielectric grease. Kickstand switch use some WD-40 and make sure the plunger moves freely. Next time the tach goes wild try wiggling the key a little. If it smoothes out then you may want to disassemble the ignition and check contacts clean as repair if needed (chances are it will need cleaning at least)

Well, I don't pay too much attention to lower speed/RPM's either,
but here's a shot I have showing 5500 ± RPM's @ 80 ± MPH, w/ stock size tires.
(and time for a fuel stop too!! LOL)

Yeah, I noticed when you get the bike up to that speed or higher you can actualy watch the fuel gauge needle as it moves down...

(and kids, taking photos of your dash while going 80 mph is not reccomended...)

Actually, I was taking a pic of the road ahead, as I was heading to the Erie Pot-Luck Jamboree, not just the dash. That's just a piece of the entire photo.

Probably a few things I do on my Vulcan that many others shouldn't do, especially kids!!

Do as I say, not as I do. Ride Safe!!
