Ok I took the thing out and got it good and hot and ran it up to the Rev-limiter in second and third gear. Looks to me it is set to 5250 this is my best guess
I was kind of busy watching where I am going, did not even look at the speed odometer.
This is plenty I would not suggest it be made higher would not be good for the engine.
I don’t know if this is the same cutout that occurs in 5th gear at 100+ miles an hour. it may be that in 5th gear at around 5250 rpm you are going 100+ mph. probably will not drive this bike a 100 or so...
Thanks

Thanks for the info, appreciate it. What did you gauge your RPM's with? Those that are technically minded will probably want to know.

Rfury;

Great info! Where did you connect in?

Cheers

 

[woodenhorse]

Way to go Rfury, thanks!

 

[Snuffdog76]

Very good info. I think it is safe to say if any of us want to go over 100 we need to install a 6th gear

Sincerely, BarFury, no disrespect here. I know you can do this .

Another way to determine max RPM is to do the math. Run it up to fuel cut in 1st gear and note road speed. Factor in rear wheel RPM based on tire circumference. Use the following ratios for the rest:
Primary reduction: 1.935
Secondary reduction: 0.944
1st gear ratio: 1.900
Final reduction: 2.818

I believe that 5th gear is road speed limited and 1 through 4 are engine speed limited based on a previous thread where one forum member observed that fuel cut occured around 100 mph in both 4th and 5th gears.

Even 10th gear with all the torque in the world wouldn't get you over 100 .

The ECM takes in a speed, rev, and TPS reading (probably some more too) The ones whos bikes are stuck at 100 are probably programmed if Rev is > 5400rpm (or whatever cutout is) stop, or if speed is> 100mph stop. The TPS &Revs gives the fuel mix getting pumped to injectors. My bike i have had to 108, chopped claimed just beyond 110 with his speedo on his bike, and a few others claim higher than 100 mph, I know my bike is still climbing fairly rapidly past 100 so could just be that is the extra little sling i get since i didnt stay too long, but it could be a few bikes are different from being a truely California emissions free bike, some jackasses at the various shops playing around trying to unrestrict the fury, or a batch of ECM's that arnt govorned.

VTX-1300's can do 115-120MPH (*GPS) in fifth gear. Don't know how the VTX gear ratios compare to the Fury.

 

[imwright1985]

Careful imwright1985, you are starting to sound like BarFury although not with his eloquence that comes with age .

Well BarFury atleast has a clue unlike some of the people on here that are just like "THIS BIKE IS AWSOME i can do 200 MPH on it, and am getting ready to bolt a turbo up, I woop HD's all day and can pull 5 B%$%^@ on it at the same time beating a HD" that we get at times. BarFury has alot more technical interest in the bike than I do I just want it to look a little cooler and Ride it rather than tear it apart and load my bars up with diagnostics stuff (Im going to take it to the HD dealer once my intake arrives for a dyno tune $80).

I think BarFury since he has an AFR gauge hooked up and is trying for a tach is just looking to tune something like the PCV on his own figure spikes or drops in AFR note the RPM then tweek in PCV from there (Thats all you need for tuning and you got the Backside for seeing if its got enough power)

the install manual will tell you how to hook up the Tach adapter.
you need to install it for the tac to work correctly it hooks to both coils

Not withstanding, I believe Honda's spedo is set at +5mph for liability issues?

I checked mine with 2 pace cars and a your speed is ___ sign, mine is dead on with all 3 havent checked on gps though

I just connected to both coils

use the tach adapter, you must connect to both coils

I have a stretch of road here in San Diego that has about 5 to 8 of those speed reading signs, I'll head up that road this weekend and report back to you guys (it's a twisty, fun road anyways )... This subject just keeps coming up again and again... again... Hopefully that will squash it, not saying that I don't believe you, just saying 5 signs is better than 1.

Haven't explored this issue yet. I would think a simple, hand-held, Garmin-type GPS, which I and many others on the forum own, would resolve the question once and for all (plus-or-minus a coupla' MPH allowance for instrument error). One should be able to Velcro-strap it to the handlebar and get some pretty accurate readings. The Fury is quite stable at speeds of 90 to 100 MPH; just don't do your testing in a crosswind, and don't get a ticket!

Cheers

OK,let me get this crap strait for you guys.my fury will do 67-70 with no problem,get me from a to b,so!what else do we need.oh yea,i look good doing that 65-70.yall ride safe.
