back from the dyno...

[wannabfast]

took my bone stock 796 to the dealer to get a baseline dyno before i start modding it..
Baseline dyno run

pulled a 76hp and 51ft/lb

not bad considering its stock

i never noticed how red that rear pipe gets when riding until after i saw the video again... that pipe goes just past the left thigh when you have your legs down

well its glowing nonetheless

The pipe will get pretty hot sitting on the dyno as you are revving high with very little air passing past the engine.

There ought to be a box fan at full tilt if that's an air cooled engine. . . .

yup, that's the way i've seen it.. big ass shop fan.

there were 2 large fans at the front of the bike, blowing air past both sides and front of the engine

The glowing pipe is because of lean stock fueling. Once you get your fueling sorted out your cylinder head temps & overall engine temps will go down.

For reference this is what Ducati claims in its website:

Don't these bikes have a catalyst in those bugles?  If so, that will make them super hot pretty fast.

Nice, where did you get the bike dyno'd at?

The link to the Ducati website lists the Monster 796 at 84hp (64kW)@ 8250rpm of power and a torque to 58lb-ft (78Nm) @ 6250rpm.
Which is at the crank, not the rear wheel. 
With 10% loss due to the drive train, it would be ~76hp and ~52ftlbs.  So, you are right in the ball park.  Time to mod!

I have seen this on other Ducatis as well.  The rear pipe glowing due to heat.  Most dynos are set up for inline fours, which have the headers on the front, right in front of the fans that blow on the bike to cool.
Looks cool.

Good Luck!

the cats are in the muffler bodies
heres another video of a different run, and you can see it change from glowing to not
2011 Ducati monster 796 stock

and heres the dyno sheet, its very similar indeed

It's a fact that the overall temps get lower upon richening the fuel mixture. Modding this one, I assume, will entail a fuel mapping tune of some ilk, and also new race-style mufflers that don't have cats in them. So if the superheated cats in the stock cans are contributing to the glowing pipes, then that is one more thing to lower the temps of the pipes.

I bought a Termi kit right away and subsequently had the whole exhaust on my bike ceramic coated, so I really never saw any glowing pipes. I know all of them do it with stock fueling, but it's more common at the header. Having a red hot pipe at my inner thigh would give me pause. I don't think I would want that. The simple fact that everyone should know by now is that the stock fueling is kinda bad for the bikes. It's too lean, and lean runs too hot. They have to be lean in order for Ducati to get past EPA regs. Then there is the profit they can make on the direct remedy, which are the Termi kits. If anyone wonders how Ducati can afford to replace all the plastic S*R tanks the Termi factor would be my guess. But I digress.

Of course there is the insane heat wave happening. Every time I open the door it's like I'm checking on a pizza.
