What are YOUR Rpm's?

RE: What are YOUR Rpm's?
Bugga! I've just been on a high speed ride & didn't bother to look at the tacho. If I did I could have said rpm @ 200km. Fun ride on the outward leg. Went with a friend from work. He rides an arm chair (1300 Royal Star). Thank goodness I was on my own on the return trip. My 87 out powered it, out handled it & left it standing on the open road. I know that 160km = 6000rpm though.

I can't imagine gear changes like that manual suggested. But I'm gonna try it on my ride to work in a 1/2 hour for poops 'n giggles ... maybe I'll leave my left blinker flashing for dramatic effect too. I'll sit up completely straight and brake at everything too.

What kept going through my head was, "this is my bike on quaaludes". I shan't be doing that again anytime soon. Riding like that I also wondered how much less fuel I'd burn through and how carboned up my engine would get if I rode like that all the time.

I just live over Portland Hills, just behind you! I go to RPM cycle all the time.

Havent seen your bike around. PM me if yo uwant to meet up for a ride sometime. We'll figure out that RPM issues on the Old Gysbrough road.....hehee

She's a white (rashed) '87 1000f with supertrapps, btw. She has just under 76,000kms on the clock. I've had her for 6 years and have had her around the Cabot Trail, across the Cat ferry and down through the North Eastern States. She's climbed Mount Washington! You'd prolly hear my cam chain rattle coming before you saw her too; she's loud! (have new cc and cct in boxes in shop waiting for time for install) And it would be cool to go for a locals huricane ride sometime. We could switch at 2k rpm all day long!

First off, sorry for bumping an old topic but thought didn't make sense to create a new one for the same question, basically.
It's time for me to replace the chain along with the sprockets, so I noticed I currently have a 45 rear sprocket. Far from the original 42. So I was wondering.... is this the cause of my speedo showing almost 160 km/h (100mph) at 5000rpm in 6th gear?
Closest I've found was Shadow's, 100mph at 6000rpm, still that's 1k rpm over.
So, is that correct? Then I'm sticking with the 45 sprocket, unless my tach or speedo is wrong?

Not as far as I know. At least on last generation 1KFs, the speedo does't run off the front wheel but on engine speed in gear. Thus, your speedo should read the same at a particular RPM regardless of gearing. 100 mph at 5000 RPM would equate to about 210 MPH at redline. 5000 RPM should read around 75 MPH, if my recollection is correct. That being said, changing your gearing will effect your speedo's accuracy.

I undestand that, but still... running at 5000rpm doesn't feels like 80mph at all, I easily overtake any vehicle on the road (open roads and highways) really fast, that's why I'm confused with this.
My other bike, the GPz 550, does 75mph at 5000rpm, and is not even close enough to how fast the CBR goes at the same engine speed.

No offense, but I doubt your GPZ does 75 at 5000 RPM. I found one source on the web listing the GPZ's 60 MPH RPMs at 4706 ( http://www.thomasonfam.com/Moto/gpz550.html ) which would mean closer to 65 for 5000 RPM.

Well it's actually around 5,500, check out this post from another gpz owner, I'm not the only one

Actually it's about 5,400 rpm at 75 mph in 6th, and at a slower speed I came up with 3,000 rpm in 6th gear doing about 43-44 mph.
Tested the GPz speedo is not far from accurate, wish I could say the same for the CBR, will borrow a digital speedo and test it this weekend just to make sure.

So 5400 at 75 would mean about 69 or 70 at 5000, and assuming that the GPZ speedo is a bit optomistic (most are) then you're getting closer to an actual 65. Remember that changing the profile of your front tire, or wearing it down a bit, or improper tire pressure, can affect your speedo accuracy, since the outside diameter of your front wheel will be affected by any of these factors. In any event, 5000 RPM on a 1000F is not 100 MPH unless you're running extraordinarily tall gearing- and even then your speedo would still only read around 75 MPH.
