They're not that bad. They just take good throttle control.

I'll buy that, IF they are set up right

Since that photo was taken Bob 37 has changed the rear rotor to a slightly larger O.D., added my billet rear brake hanger, Posh / Faith LED tail light (VERY cool), A-Tech Carbon fiber rear fender, Tealdo radiator, Titanium nitrided forks (Black), Raybrig headlight with Frayed Sanity wiring upgrade, custom Paul Kondracki lower triple tree painted gloss black, with a gun drilled titanium stem, Rizoma bling$$$ mirrors, Rizoma bar ends, Nissin front brake calipers, repainted the fork stanchions gloss black, touched up the RED on some of the body work....

Oh yeah I have a Works billet clutch slave on the way!!!

But OTHER than that not much.....
Fairly stock bike....

You have a sickness my friend, I went and got professional help!
She took my mind off of Moding my bike but she almost blew my heart out too.
Dang she was worth it. Ha!
Rock on Buddy!

Wheels are Dymags, but have since been swapped out for Carrozarias(sp?). After bending / breaking two front Dymags it was time to move on. Swinger is a braced 1100 stocker.

Hey Bob!

[Bob 37]

What up Scott?

Greg let me out of the garage long enough to check out the board.

[Greg Couch]

Now get BACK in the garage!!!!



(BTW Bob's "Quart of blood" technique STILL whips me at the drag strip....)

Oh yeah and 2009 bling....



Coming SOON....DIFFERENT triple trees (New Kondracki one off design)
NEW Bling aluminum box section swing arm (Wheelie from Japan)....

Been my experience too...I think they're as immediate as your hand is. I just followed Seths (scs) directions/recommendations for jetting and needles and it pulls real strong everywhere in the rpm range.
Wanna go faster right now? Turn the throttle.
Don't wanna? Hold steady.
Perfect for the winding roads I like to ride. Flat slides rock.

Winter mods were:
Degree the Yoshimura ST-1 cams at 105 intake, 110 exhaust.
Tsukigi titanium 4 into 1 sewer pipe.
Pete's ZX-11D brain box.
Tuned and jetted by Bob 37.

This is on a well used 1224, with all out porting and matched intake boots by "Short block Charlie" (Kwick's buddy).
Double valve springs, Stick coils, Dymags, FP 2.5 kit WITH the airbox, Pilot powers inflated at 36 psi..Running on 93 octane pump gas..

Looks like a fudged dyno run to make it look like you have more power than you actually do.... Why wasnt the dyno set at SAE???? Instead of STD? STANDARD?

[krexken]

If his return dyno session uses the same correction factor then there is no fudging.

[dndowns]

But to say his bike made 172.3 hp is fudged. Ive played with dyno software and its not hard to show a guy 10 to 15 more horsepower by fudging a few input values into the software.

Returning to the same dyno will only show him his power increase with dif mods.. Lets say he makes another pass with another mod and it makes 180hp.

180hp-172hp= 8 hp gain with this mod... Thats the only info that can be taken from it.. AND IT CAN STILL BE FUDGED........

[schmoo]

The correction factor is on the sheet 1.05 so it made about 164 SAE still pretty darn impressive.

a std run vs a std run is the same comparison. its not fudging, in fact its just the softwares computation of a different theories of hp evaluation. its not cheating of any sort. if both runs are compared using the same correction factor then its an apples vs apples run. i have owned 2 dynojet dynos for the past 15 years and you cant really make one "cheat" if you compare runs with the same correction factor.

[tanner]

fine work there Greg---that's should be palenty to keep you happy and hauling butt fairly well. ...talk about wringing every last bit. Way to go!

People complaining like this is why some people won't post up their dyno #'s. It is obviously a strong engine no matter what. And just because the dyno operator had it set to STD is not a big deal, I don't think he was trying to fudge anything.

taken from a Mustang car website, but may be relevant here.

Since we're talking about dyno's, here's an email I sent to Dynojet:


Does atmospheric conditions and elevation effect horsepower readings? For instance, say you dyno a car when the temperature is hot(say 100 degree's) and then dyno it again later in that same day when the temp is 60 degrees. Would the temperature effect the horsepower numbers? Or would the numbers be the same due to a correction factor, say like the SAE setting? Also would a car read less horsepower if it was at a higher elevation than it would if it were at a lower elevation on the same dyno?



Here's their reply:


You have touched on the whole purpose of the Correction Factors. The various formulas, SAE, STD, JPN, etc. are all mathematical formulas that take into account the various weather conditions and try to ‘correct’ the measured output on the Dynojet to the projected equivalent if the test was performed under ideal conditions. So, if the temp, pressure or humidity does change, theoretically it will be accounted for and offset by the chosen atmospheric correction factor. In the US, the SAE correction factor is thought of as the most widely used.

These factors do ‘assume’ that the vehicle is properly tuned for the particular conditions, for instance a carbureted engine that is set up for seal level, would need adjustments when moved and then tested at higher elevations. But, if all the engine management parameters are correctly dialed in, and proper dyno testing procedures are followed, the power from one day to the next should remain equivalent.
