Tach Connection?

100 MPH just isn't enough...

I'd like to know the answers to these questions too. I hit the wall at 100mph and it feels like she's got more just the rev limiter/governor is holding her back.

Is there a way to bypass this? I know it isn't meant for speed, but sometimes you just gotta do it you know? I'm not always on my Hayabusa when the urge hits me

I think it needs a 6th gear and this wouldn't be a problem

Its a chopper, not a race bike... slow down, enjoy the ride... No, there is no computer override for the bike yet... There were some institutions working on it before, but we haven't heard back from them...

Just because it's a chopper don't mean it can't go faster

Clueless;

Have you as yet attached a tach to a Fury, for test or tuning purposes? Is there a tach-signal wire in there somewhere? Where does the ECM get its RPM Signal pulse from? I have a tachometer that I'd like to hook up, for diagnostic purposes, but I'm not sure where to get the tach signal from. Also, do you know, for certain, where (rpm) our Rev-Limiters kick in?

Cheers

Very interested in everything just asked.

Yes, hopefully Clueless get's back with us here shortly, kind of interested in that information as well...

I hooked up the test set to mine when I had the cold idle problem, it gives rpm among other things. I think the ECM uses the CKP sensor for it's input (crankshaft position ) I am not sure about the rev limiter, I will check around at work and see if I can find out. 6300 rpm stick out to me, but that maybe the Goldwings. Not much help, but I will check around.

Thanks, Clueless. Sounds like several of us are really interested in having some definitive answers to these questions. We'll anxiously await a report of your discoveries.

Cheers

The fury uses two ignition coils with the same primary wiring that has been in place for over 100 years. When the motor is running the coil is hot and switched with the ground lead which can also used as the signal for older tachometers. It ain't rocket surgery.

For test only purposes simply clamp an inductive pickup onto a secondary lead using a modern tach or timing light to get your RPM.

The Fury uses the CKP (crank angle) Sensor at the rear of the alternator to, among other things, supply engine speed to the ECM. It is not intended for tach input.

It would appear the fuel cut occurs at 5000 RPM since the dyno charts cut off there. Peak power occurs at 4200 RPM.

I've got an old, non-inductive, tachometer laying around the shop, and my timing light doesn't have a built-in tach. I THINK the Fury ignition operates in the "double-fire" mode (once every 360, instead of the more conventional 720) which means I'd need a divider for my tach. I think I need to order an inductively-coupled unit with a built-in divider, like a TINY-TACH for instance. The Honda Test Set that Clueless was referring to must be picking-up its tach signal off the crank angle sensor.

Also, I thought I remember seeing somewhere that the Fury hits peak torque at 3500. No?

Cheers

BarF, is there anything out there you won't argue?

NO! (emphatically); I'll believe anything anybody tells me, until my intellect and/or experience tells me different.

Cheers

Maybe it's the radiation, but it seems clear that your intellect and/or experience is failing you miserably in this instance. Zero for Five .

Getting a little hostile there Gar ole buddy?

Cheers

Maybe Clueless can correct me if I'm not entirely right... The Power Commander, when hooked up to the bike, registers rpm for diagnostics. I was playing with it a little after I installed mine. Seems to be pretty dead on.

And why do you want to go that fast on any cruiser? Enjoy the ride and go slow enough to piss off the cagers. Carry some pennies for the tailgaters. Always good for a laugh.

Just a little Fred. It kinda wears me down when you frequently follow my posts with an unsupported argument . I can back up everything I post as 'fact' with legitimate references rather than 'intellect and/or experience' and I would think you know that considering the eMails and phone conversations we have had, not forgetting my track record on this forum. There is no question that your intellect and experience related to our topics of discussion go beyond the average poster, at times, to the point where you talk over our heads, a tactic often used to baffle and subdue the common man. As with Chinese water torture your approach paves the way to discontent .

I confess that I did take a shot at you with my first post on this thread. You profess to be an expert in so many areas that I was surprised you stumbled on 100 year old technology as shown in the shop manual. Nonetheless, considering past threads, you initiated the challenge.

Ok Gar, I had to bite my tongue long and hard before responding, but that’s it; you and I will have no further exchanges, since you seem hell-bent on creating a censoring, denigrating, and hostile environment/situation. I didn’t join this forum to get into a pissing contest with you or anyone else, especially someone who doesn’t even own a Fury.

Might I suggest that you go buy a Fury, along with some pipes, a fuel controller, an after-market air intake, and some other goodies, then climb down into the arena here with the rest of us and start getting some real-world, hands-on experience with the problems many of us are having. Then you can comment from a position of first-hand experience, instead of pontificating abstractly from the sidelines.

Cheers

Hey Guys, interesting read and all. I don't know about others on here, but I'm always interested in the truth. If either of you can provide it, then I sure would want you to do so. I don't know much about engines and efi and such....so any truthful info provided is sure welcomed. Gotta admit, your "discussions" are entertaining though.......

lol.. I agree. We need this entertainment from time to time. I also agree that those of us who don't really know shit are hoping to get some accurate technical information so we don't screw up our bikes and waste a bunch of money. If there has to be some "heated discussion", or even a fist fight to provide this, then so be it.

Thanks for your help.

Most of it is fairly close, if it seems questionable then just sit back or ask if anyone else did it


Just realised im at 666 for my posts.... im gonna let it sit for a while so i can be EVIL
