Topic: My 650 woes getting on a DYNO.

[Soos]

I called the big timpanagos harley shop today hoping to get a run on their dyno.
It's a BIG Harley shop to say the least.

At first the parts guy and the dyno guy were REALLY against letting a old Honda in the doors, let alone on their dyno.
They stated "it would hurt your bike possibly, we can't take that risk"
To which I replied, i'll sign any waver needed, i just want to do a dyno run.

once i mentioned the dynatek ignition I run, they stated "we can't tune a dynajet on that old of a bike"
My explanation that it was for the ignition, and needed NO tuning, was either ignored, or unheard by them.
They never could that it wasn't a DYNJET, but was a dynatek, and had nothing to do with the fuel, and everything to do with timing and advance curves...


So i thanked them, called back and asked to talk to the manager.


I explained how i felt they were not wanting a metric on their dyno(the impression i got anyway) in the doors.
He apologised and asked about my bike.
I explained to what it was, and asked if they could hook a lead for the tack readout to the dynatek unit I was running.

Well he called back, and said they could not tune my DYNAJET but are more than willing to allow me to run on the dyno for a RWHP run though.
I tried to explain I DID NOT have a dynajet, it was dynatek2000 ignition module with tach leads I was hoping they could hook up to So I could see at what RPM I was producing XX HP at.

He didn't get it, and curtly said, the dyno run is 90.00 an hour, can you afford that?
I hung up.

^%#&*%^#(*&&*#@$^%^#!$%


I guess i'm just ranting..... nothing to do with SOHC's, but i didn't know where to put this.
the bad review section?

reminds me of that cheech and chong skit, "dave's not here..."

idiots. 

[MRieck]

 If they are that retarded to think the bike is fuel injected......well.....I don't think I'd trust them.

[bwaller]

Keep looking there are good folks out there that will surprise you Harley or otherwise. Sometimes you have to get away from a big-hustle shop and into the sticks a ways!

[kghost]

Well when I get my dyno up and running your welcome to use it....its old and not real high tech but it should work.

Sorry I'm so far away....

[Soos]

Texas huh?
Thats not that far away!

You get that thing running, and I will definately try and make it there!!!

I need to exercise this motor on more than just 20 mile canyon rides occasionally, and the poor use of commuting 6 miles each way to and from work.
I'm sure my exhaust is slowly rusting from the commuting... and the canyon rides are entertaining... but theres nothing like riding for a day or two straight!


I just heard an ad on the radio this morning...they are advertising their dyno services for FREE to hardleys.

I'll have to post a pic of the building at least.
It is unique to say the least. Something like 70%+ recycled bits and pieces from the old Geneva steel mill....

You lost me on post #1

So you want to pay 90/hr, and hooking up the rpm, is the issue?

Sounds like they were willing to do it.


I got a question re use of dyno..

 Will a CB750 with mechanical tach, allow it to read rpm?  I thought maybe it ca read impulses of the plug wire?


Please show the building.. sounds very interesting..

[MJL]

Other way around. They were making excuses to not let a Honda on their dyno.


I would have told the manager that yes, I could afford $90/hr on the dyno, but no, not at their rude shop.


Google "homemade dyno" there are a number of webpages on the subject.

[Soos]

I doubt any dyno still around will read the stocker tack output(cable)

But I have DYNA2000 on my cb650(not cb750), and it has tachometer outputs..(for an electronic tachometer)
I was hoping to actually find what RPM I am making HP at.

Paulages got a Dyno shop to hook up to his DYNA2000 tach output, was hoping that these guys were able to do the same.
And no 90.00 isn't too much to ask.

A dyno would be great... and at their shop, all I would get is the highest RWHP reading.


Having programmed the dyna2000 to (as far as I can tell) a good power curve..
I want to try thew 4 different curves and see which one affects the HP at certain RPM's so I can actually tell whether the subtle differences of the 4 curves I have programmed are doing what I want(expect).
After finding out which curve is performing the best so I can fine tune it even further.

The attitude I received was enough to turn me off of them.
But without the RPM readings it's almost useless in terms of tuning for me.


Now even if Kghosts dyno were to not have a tach reader...
It would be worth it to tool around texas a day or two, meet another member, and play on a dyno for a bit.

It should be able to read off a plug lead though it can be difficult with metal core wires. It can interfere with the dyno computer itself secondary to electrical interference. It has happened to me. The tach output wire on the Dyna 2000 should work better (that's basically how they measure RPM on modern bikes ....the tach lead off the ECU). The big problem with those dyno guys is they kept referring to a Dynojet unit which, I presume, they meant a Power Commander. That device is used to tweak FI bikes. If they think an old Honda is fuel injected then they are retarded. The second reason they are retarded is Soos said over and over again he has a Dynatek ignition system but they didn't get it. Dyna makes plenty of ignition products for Harley's so if they don't know the company they are retarded.

i made the mistake of paying $80/hr to a triumph dealer for a dyno run, and the morons didn't even rev the engine past 8K, even though i told them several times that i already knew the peak power to be at 9,500 RPM. i'd be hesitant like soos, too... if the idiots don't know the difference between dynatek and dynojet, then they'd probably also think the thing was gonna explode at about 7K RPM.

also at that dealer, they wouldn't even attempt to use the tach lead i had already prepared. they used the plug wire for RPM. i have suppression core wires, but at moto czysz we were getting a very erratic reading that way.

Soos- surely there's a sport performance somewhere nearby? they might laugh at your bike still, but at least they'll likely be less clueless and will at least understand a four cylinder engine.

[754]

Well to me it just sounds like a simple misunderstanding of terms..and.. the tech running the dyno could probably get a better answer to the owner of the 4.

It is not your run of the mill  bike they put on there and it has to be setup differently.

I think the service manager was trying to determine  wether you were willing to pay before further discussion. I think the Dyna products for Hd are named Differently hence the confusion or thinking you meant a different product.

We have a new Dyno guy here that works mostly on HD, but runs many other bikes on the dyno, he seems to know his stuff. A "busa rider at work the other day went to the Beemer dealer here in town.. was not very happy with the dyno work they did.. he was trying to sort out lower rpm issues.. said it pulled 175 tho.

I think we are Dyno-rich in our small town..
BMW dealer has a bike & truck one
The H-d turbo guy has one
Goldammer has his own(mostly private work)
& The sled Freak has a dyno for them

.. might be a few more in town, i know an engine-builder that has an enine one in his shop. we are in a town of arond 120K population

[kghost]

Ya also have a hell of an Airplane company in your town 754.....

[Soos]

I know of one place up in ogden, UT.
A co-worker(way high up in the chain of command at work, 3rd from the top) told me of.
He has them do all his overbores, parts changing and tuning to his race bikes.

If I remember right they wanted like 160.00 for dyno runs.
However thats for dyno runs/tuning(jet changes/re-mapping FI, or timing changes) until the bike owner is satisfied.
So it's not like it's limited to 1 hour.(except during peak seasonal use, then it's 100+/hr)
 
I might have to trailer the bike up there shortly after the riding season, as thats when they are the least busy on the dyno from what I have been told.

Heres an interesting time lapse video of the place being built.
Not the best view though.


I have heard rumors of a home shop that has a dyno... but thats as far as I have found on that one.

Kghost.. are you meaning Flightcraft ? We have a lot of aero industry here now..

 Baron STOL I think does conversions on Beavers.. saw a sticker for that in a HarrisonFord/Ann Heche movie where they crashed one and fixed it with a stick & a carrot..

 Northern Airborne Techonology (N.A.T.) builds a lot of avionics gear for a lot of different craft..

 Othercompanies building more stuff here..

this clip i took this summer on the local honda vintage meeting in ponoka,it cost 60 bucks,first they did my buddys harley,and then they did this cb 750.....
all they did was put a sensor rod into one of the pipes,and hook up a clip like on a timing light to one of the sparkplugs cables.....it could read speed,tach and fuel mixer no problem,they told you if you where lean or rich at all the rpm's....and ofcource hp and torque...
enjoy the clip>>>>>>

[Soos]

THATS EXACTLY what I want to hook to!


Things work out, the A/F ratio questions I have with these new carbs will be easily answered.
Plan on hacking the spare 4-1's I have into a tester system by welding 4 bungs for o2 sensors on it.
But thats for another thread when i get the parts.

I have a lead i'm going to chase down next week.
I'll get my bike on one eventually.

[Hush]

now thats what I'm talking about Otis! ha ha
They took that 750 well over 7k, notice the spare earmuffs no one was bothering to wear!
Imagine how embarressing it would be for your pride and joy to sh*t itself with all those bike fans watching!

[martino1972]

you had to tell the dyno guy till how far in rpm's he could go...and sign a waver....

[kghost]

Yup FLightcraft...have alot of time moving thier product thru the skys.....

COmpany I work for has basically all but one of thier convair conversions....and 2 of thier 727's

DeHaviland Beaver is my absolute favorite aircraft. i've had the privelge of riding in one while hunting in canada in 2004.
