Speed healer shock and other babblings

8 per cent. That's how far off my speedometer was, if my GPS and Speedo Healer are accurate. I started out with a -6 correction. I just kept pulling over, I was on the interstate, and adding a .5 percent until I was satisified. I knew the speedometer was off. But I had no idea.... It sure is nice to have a speedometer that is right on the money. It's kind of like having the suspention set up correctly. Right is just soo right.

Dunlop Road Smart tires. I didn't push it in the corners, but so far. so good. If you want a tire that is easy to erase the chicken stripes on, this is it. My back ones are gone, and like I said, I don't think I was running very hard.

After 5 years, my battery is weak and needs replacing.

So...do they make a speedohealer that doesn't mess up the odometer?

I don't think so, it's either one or the other from what I've read.

It's 8.5% give or take a little based on tires.

I seem to be doing about 85 when keeping up with traffic... in town.

Looks like I need to Google this speed healer thing.

I thought a speedohealer helped your odometer by putting the correct milage on the bike by correcting your speed. If your speedometer says your clocking 80mph for an hour and your only running 73 then your clocking more miles. When your speedometer is corrected then why/how does that mess up your odometer?

Don't know how or why, but the odometer on the 919's are pretty accurate.

I've checked mine against a gps on a few occasions and those times traveled 60-100+ miles and the odometer was within a few 1/10 of what my gps said.

For the most part, anything over about 50 mph I just look at my speedo and deduct 5 mph for my close to actual speed.

I found that when I installed my speedo-healer, I could adjust for speed, or distance (odometer). Not both.
Factory, the odometer seemed pretty accurate while the speedometer was optimistic. I believe that I adjusted 7% for speedometer accuracy letting by odometer lag.

I plan to die young, as late as possible.

It's nice to be able to look at my speedometer and not have to do the math.

If you had a clock that always told the wrong time, you'd re-set it, wouldn't you. This is one of those things that I don't put up with anymore. Don't know why it took me so long to address this.

I find most analog 140 MPH+ speedometers useless anyway. I don't want to spend the time with my eyes off the road trying to see where it's at.

GPS. Deadly accurate and easy to read.

I just don't look at my speedo. Go with whatever feels good that day.

I remember once counting all the numerals and all the hash marks on the stock speedo... it was ALOT.

I can't go by what feels good because 80 usually feels about right to me. The local law enforcement frown upon that.

My useless guage is now useful.

Why are these SpeedoHealers so hard to find?

I searched every MC Parts place in my Favorites list, and even Googled a few extras. These are the results of a half-hour search:

Company: Sell?
Star Cycle: NO
Bike Bandit: NO
CyclePages: NO
J&P Cycles: NO
Motorcycle Superstore: NO
Phat Performance Parts: NO
Competition Accessories: NO
Rider Station: NO
2Wheel Performance: NO
Dennis Kirk: NO
Fast Cycle Parts: NO
GDL Cycles: NO
Motorcycle Pro Shop: NO
SoloMotoParts: (YES, but none listed for 919) $110
Cal-Sportbike (ONLY authorized US Distributor): $110

So, it looks like, after I went to the HealTech site ( http://www.healtech-electronics.com/ ) and checked out this contraption, I'll be spending yet another $110 plus S&H on my 919! Dang! But hey, I gotta have all the cool toys on my bike. The unfortunate thing here is that more than half the "cool" stuff I've bought for my bike that I thoght was would work so well ended up not living up to the ads and promises, or the just plain sucked, SO I ended up selling more than half the accessoires I bought for my bike! The other "crap" is still sitting on a shelf in my garage. The ONLY items I've bought and KEPT on the bike are: PC3USB, Yosh muffs, Motovation sliders, Gorilla alarm, and K&N air filter. Everything else sucked! But, as usual, I'm going to take a chance on this piece because I believe it works as advertised. I've spoke to people in the forums who say it works awesome. And I have no doubt at all that my speedo is not accurate at freeway speeds.

Just ordered one!

$110 plus unknown shipping charges from www.calsportbike.com

If anyone wants it, the part numbers that work on the 919 are
#SH-V4 (that's Version 4, not for a V-4) and/or #SH-HO1
Both part numbers work. I'm actually just assuming those are two seperate part numbers.
If not, the number is SH-V4+SH-HO-1.
(The "+" threw me off).

So now, if this freakin' thing is as worthless as half the other stuff I've wasted my money on, I'm pushing my bike over a cliff (or maybe just my wallet!).

I've always been told that speedometers read 10% optomistic from the factory - good to hear it's not quite that much.

I had a Speedohealer on my last 919 - it was a very easy install and seemed to work quite well. I still have it somewhere and will install it on my new bike whenever I finish the project...

I ordered one from SoloMoto - I've dealt with them before and they have free shipping on many items. Sometimes they list items not actually in stock...only complaint. But they DID find some Sato's for me after the world was supposed to be out, and for a lower price than anywhere else.

I agree about Solo. The first few things I bought online after I bought my bike were from Solo. They had the lowest prices on almost every item I was looking for! And yep, free shipping! Got my Power Commander from them, sliders, and a ton of other stuff. Their customer service is tops too! Great bunch of people who are not afraid to pick up the phone and call a customer if they have any question about an order or the application of a part. This is rare in the online retail world.

However: they didn't list the SpeedoHealer for a 919. I suppose I could have called them, but it was easier to just use HealTech's only authorized distributor in the US so I did.

The bad thing about such a good thing is that even they are out of stock on the one for my bike! But they were nice enough to post on their site that they have a limited supply of the units but are expecting more as they arrive from the manufacturer. Apparently these SpeedoHealers are so freakin' popular that even the manufacturer can't keep up with the demand! But Cal-Sportbike e-mailed me after I placed my order to let me know that they expect my unit to arrive at their warehouse in the shipment coming in 8-10 days. They gave me the option to cancel my order at any time before they fill it (unheard of in most online purchases). Also, they don't bill your credit card until the item is actually in their physical palms and being put into a shipping box to go out.

I'm pretty excited about this little magic part. Until then, when I'm up in the triple digit range, I'll just reach into my pocket, pull out my calculator, do the math, then adjust my speed accordingly.

Stock speedo's on the Japanese bikes are 7-8% optimistic at freeway speeds.

That error is non-linear and will increase as your speed does so by the time you are doing an indicated 130mph your speedo can be off by as much as 14% etc...

The speedo error is intentional and the odometer is calibrated correctly.

So it's kind of like zeroing in a rifle. You have to pick the "range" that you're dead on. Mine is 80mph. At 40, in theory my speedo is reading a bit low. At 120 the speedo is reading a bit high, but not nearly as much as before.

I guess that's why they call it a speedo healer, not a speedo Perfector.

Sniper, I want to make sure I understand you. You're using a Speedohealer and your speedo is accurate at 80mph, but it reads low below that speed and reads high above that speed?

I wonder the degree you'd be off after zeroing it on at 70 or 80, as you said (relative to the other speeds). That's kind of the danger zone and the area I'd like to know for sure how fast I'm going for ticket times, but it'd be nice to know I'm in a reasonable range everywhere else.

The 919 comes with a speedometer? All I see is an easily read tach and something that resembles an instrument but has far too many numbers and hash marks to be useful without staring at it. The only reason I look at it is for the trip meter. I honestly wish it had the same sweep but topped out at 90. Above that I'm usually too focused on other things to look at it.

By the way, in top gear with stock gearing 5000 rpm is 79.6 mph, and 100 mph is 6280 rpm.

Rob

If it has already been done, it is safe to assume it is possible to do it.
On the other hand, if it has not been done never assume it is impossible to do it.

What we need is a Mathmatician, are you listening Rob, to make a graph that charts actual speed, indicated speed, and engine rpms in 6th.

And I agree with all who think the speedometer on these things is nearly usless. They are hard to read, and in stock form, very inaccurate.

SG, it'd be easy to find out. Just stick the GPS back on the bike. I fugure it's going to be very close to 100mph, and just a little off past that. You can get throwd in the Grey Bar Hotel for triple digits in Indiana.

I think the guy who figures out how to take the speedometer apart, put a face on it with the hash marks in the right places, and an easy to read numeral by it, and seal it all back up, will make some money.

Put a big recticle on it. Call it the Snipeometer. Cut me in on the profit.

I have a feeling they make speedo's these days conservative to deal with the speed camera/radar issue. Here in Queensland, they give a 9 kph tolerance, in Victoria (our Mexico) they have a 1 kph tolerance. The innacurate speedo has helped me out a few times. I find a lot of cars and trucks are out by roughly the same amount as well.

I've got a spreedsheet on my site specifically for the 919 where you plug in your tire dimensions & sprocket sizes and it will give you a detailed view of your speed at each rpm.

Unfortunately the site I had it hosted on is now defunct & I keep forgetting to move the file to the new server.

I'll try to do that this evening.

They must only build in the speedo error on bikes.
I found the speedo in my truck ( Ford ) agrees perfectly with my GPS.
Same with my wife's car ( GM )
Bike is off 5+ % at 100 KPH.
I don't feel the need to spend over $100 for a Speedohealer.
I can figure out that when the speedometer reads 100, I'm going 95.
I'd rather spend the money on other bike goodies.
