Mate,
I really disagree with this. If the tuner knows his stuff, why would her not want you around?
I have used four different tuners five times since 2006. Two gave me a loaner and sent me away citing shop insurance.
One flat said I couldn't silently watch as he wanted to "protect his product".
This fellow spoke freely about everything, the good and bad and already knew pretty much what he would get out of my motor and told me so beforehand. I asked about the Aussie dynos getting 169 hp and he merely shrugged it off saying it was the riding results and the what is in between the before and after tuning that counted. not the calibration of the dyno.
Nels was proud of what he does and willing to share information and answer all my questions about his magic (my word-not his). I did NOT feel the engine abused at any time. His use of the throttle and gear shifting was very smooth. Original runs were well below red line. As the tune took shape RPM increased to 6500 and at the finish just under 7000.
He switched the screen to a large tach and speedo with a colored fuel mixture ratio underneath. Here he took 4th gear to red line and the speed was 145mph!!! He then ran up 5th gear to 170mph!!!
Now I understand that this does NOT equate to the real world - BUT I was hard as nails anyway!

My bro-in-law (a former factory Triumph dirt track racer) wanted a demo versus his new Gold Wing.
I was able to accommodate by greasing it with him in 4th. He hung for about three sec then disappeared behind.
It felt SO FINE I stayed on it until about 6K when I looked and saw the speedo nearing 140 (135 on the GPS), I shifted to 5th for a few sec before running out of highway. I WAS MAJOR STOKED to say the least. In the next couple days it was twisty time - real good ones even better than those of 92 out of Blue Mesa we rode at RAAIX. This motor between 3K and 6K is super smooth and throttle control in the twisty is GREATLY improved. I also noticed the need for less trail braking since adding the Progressive front springs and 444 rear.
Bottom line is I am now more excited to ride than I was when I first got the bike!

Then again why would he want someone hanging around.and old saying around workshops if you watch $20 extra if you try to help $40extra
I think (Jamie) the Dyno guy was more alluding to the fact that a lot of customers want results but are shocked to hear their bikes rev like they have never heard before and complain,
I may be wrong but the factory HP/Torque figures quoted are taken at the flywheel and never authenticated by any authority the Dyno figures are rear wheel horse power/Torque,
all the dyno tests I have seen, including dyno shootouts of big street machine car engines ,big block Fords/Chevs and Mopar Hemis are brutal affairs , no mamby pamby *****ing around ,if you go into the pits at a drag race meeting and listen to the top fuellers "tune" up you will see what I mean.

Hi R3Tex,

Thanks for the info'. I see from your install pics that you have the black headers and I would imagine that they put out rather more radiant heat than the silver.

I'm in Dallas and I get down to Houston alot. I wonder if I might contact you the next time I'm heading your way and take a look at the CES in real life?

Regards,
Mark

I was told that it's actually the other way round .. black ceramic coating runs a tad cooler than silver or lighter colours. Bloke that told me has been building m/cycle exhausts for 25+ years.

I'll post a pic of what I've done for a heat shield. The only problem I had, you may recall, was that my rain pants melted on the pipe and I stupidly tried cleaning it off with oven cleaner. DO NOT DO THAT. Fortunately I had a small heat shield with the Foran pipes and have made up an extra bit with a small piece of off-cut bear claw. Looks OK and works great. I can rest my legs straight down against the shield and it's not too hot at all.

 

[TOMCAT]

Original heat shields from Harley V-Rods have a multitude of twists and turns .. ideal for cutting into shorter heat shields.

I do see this as a temporary fix, but it works fine.

Hi TOMCAT,

That bloke is incorrect. The effect is described by Max Planck's theory of black body radiation. The link is rather more in- depth than warranted, and a better example is a commonplace situation: A white car and a black car are both out in the sun, - which feels hotter to the touch?

All,

On a slight tangent to the thread, I was wondering what kind of gas mileage folks with the CES pipes and Triple K&Ns of RamAir filter are getting, - and how you ride.

Thanks!

Mark

 

[R3Tex]

I ride as I d@mn well please and I got 36 mpg from Dallas to Houston at 80+ mph

 

[Mark Dunn]

That sounds pretty good for a modded intake and exhaust. I'm standard at thee moment but with a Wayne Tripp map and I get 38mpg.

I don't think the colours matters at all, unless the actually coating differs in thickness or density because of it

Surely black body radiation theory relates more to something being exposed to radiation/heat from the outside and not from the inside. From the inside an exhaust pipe will be the same and as long as the ceramic coating is the same thickness and density regardless of colour it will radiate the same heat out.

Your example of a white and a black car relates to an object begin exposed to external radiation, if there was no sun shining and both cars were the same temp at rest, after running the engine really hot would the bonnets be different temperatures...I don't think so. If what you are saying is true all my radiators in my house would be painted black to make them more efficient at radiating heat but it just doesn't matter.
