ok, i shouldn't do this ****, but i do. when you top your bike out, have you noticed what the speedo was reading? I can't get over 10k in 6th gear, all the other gears i could redline if i wanted to!
also how much top speed would i lose by going up 1 on the rear sproket?how about 2 teeth?

and finally did anyone gps the actuall top speed?

 

thanks in advance, you guys are always a huge help

 

So my question is where do you find an empty road long enough to get to top speed? Are you out at the Bonneville salt flats or something?
Not to mention all the straight roads here in Washington are patrolled with aircraft that are as thick as mosquitos [:-] Instant trip to the graybar hotel if caught.

 

i've never needed a straight road to do it, usually i don't even need an open road. and if you rode with the guys i do, you would top it out too. no aircraft in my area and cruisers don't bother when they see 150plus on the radar. just to give you an idea, my freinds have 2 gixxer 1000 a new 1000rr a 999, and a couple of 6's that are much easier to kepp up with

 

You cant redline in 6th gear because the wind is simply taking over. Your bike doesnt make enough power to overcome drag at that speed with those gears. If you went up 2 in the back you would actually pick up speed if that is the case. However slight it may be.

 

so how fast were u goin and 10k?

 

the speedo was dead set at 170, so i would say 158 actuall speed(just a geuss), has anyone else had this aero problem? and you don't think 2 up is 2 much?

 

Okay I guess stratight roads aren't as needed as roads free of traffic. I would never trust a cager if my closing rate was three times that of his pace. HellI don't trust them at the same speed!
Trying top speed runs around traffic is just plain stupid IMHO. There are onlt a couple of places that fit the bill that I can think of locally, and even then it's not totally traffic free. But Montana is only one state away from me!

 

I seem to have that same problem old1000. And he's right. You dont need to be in the Salt flats to top this baby out. I do it all the time. Mine cuts out at about 165 or so.

 

That's about where the peak HP is (9800?) so it may be the best you'll get. Some bikes do show a gain for a gear drop for that reason, that the top gear won't pull the peak HP, but being around peak it's not likely it will pull any more.

10,500 is past peak but is still a good redline for all of the other gears because it averages the peak best, dropping below peak about the same it goes over peak with each gear change. In high gear with no more shifts available, why would it go faster than it does if it's at the HP peak and stalled there? You're just about perfect for the maximum MPH where you are. If there will be any true gain it will probably be with one up at the rear. You may find that the only thing that goes up is the RPM by a couple of hundred while the MPH doesn't go up at all, maybe even drop a little.

Dropping the gear will give you a speedo error in direct proportion to the gearing change. That's not easily corrected on these because they're mechanical.
