Yes, same here. I've even quit toe-lifting, pulling for 6th gear...

I had trouble finding the OEM Kawasaki tachometer. Its discontinued or out of stock on Kawasaki's website. Not sure which, but I found a dealership in another state that had 1 in stock. The OEM tachometer is nice but expensive.

I bought my tach via Ebay. Much less expensive. Maybe try finding what you would like here (f the link works!): Kawasaki Vulcan 900 tachometer | eBay

Hot Cruiser, How well does that $20 tack work? Does it bounce all over the place? With rev limiters these days a tach is not as important as the old days. I can't justify spending $250 for a tach, but $20?? I have bought some cheap stuff and surprised at how good it is for the money, likewise I have purchased high priced products and really disappointed how poor the quality was for the money. How does you tach stack up?

i checked the link on that gearing commander web site just now, thanks to who posted the link, on my '05 800 i had installed new front and rear sprockets 17/40, stock was 17/42, so commander page says for my bike using 17/40 sprockets in 5th gear going 73.5 mph, rpm is at 4200, i think red line on these bikes is 8000 rpm, i entered sprockets 17/42 on commander page and it says in 5th gear 70 mph is at 4200, so the rear sprocket change gives my bike another 3.5 mph in 5th

WB, I don't know how well the $20 tach works. The Tyan tach I bought in 2007 cost something like $45 if I remember correctly, since that seems to be in the historical Dark Ages now! There is quite a lot of needle bounce at idle and low RPMs, but at higher revs it disappears and at road speed RPMs there is no needle bounce. I read somewhere that even the low RPM bounce can be eliminated by inserting an inexpensive electronic component into the tach wire which comes from the single fire adapter (needed on my VN900) , but I don't recall whether the component is a resistor, capacitor, or something else. Yeah, with today's rev limiters having a tach isn't as important as it once was.

Thanks HC. Tach really isn't needed on these bikes, the engine pulls well over a large rev range and you can pretty much shift by feel.

Not in my teens and 20s anymore trying to target shifting in the max rev/power range or doing any street drag racing where you would red line the engine before dropping the clutch. I thought that that was fun 40 years ago, now cruising along a near deserted back road at 50 mph relaxed and just looking is my idea of fun, guess that puts me into the old fart category, oh well!

Right with you, Wild Bill.

I just added a Versys 1000LT to the garage, which parked by the Vulcan makes for a fantastic choice of what to ride.

The Versys' supplied tach is handy for monitoring break in rpms but will be of little use after that. Its torque-tuned Ninja 1000 engine pulls so hard in the bottom half of the rev range that using the top half seems like madness.

Once I learn the general sound and vibration of a given rev number on an engine, I almost don't want the numbers to be presented on a gauge. It's distracting from the head and eyes up position that keeps me alive.

In its upper rev range the V900 just sounds miserable, and I don't want to treat her that-a-way. Don't need a tach to tell me that.

HC, WB, etc.--
I was also wondering the accuracy of a $20 tach. I can deal with a bit of needle-bounce. Due to some hearing loss and wearing a full-face helmet I have a difficult time hearing the engine well. Do you need to get the adapter for our bikes so it doesn't show half the RPMs? It seems like for $20 you can't go wrong trying one.

Also, I see these tachs with a tab at the bototm with a hole in it. Is that supposed to go on the handlebar risers? I am having trouble figuring out how they attach to the bike. This is the only way I can see it attaching.

As always, thanks for the insightful input!
