That pep in her step is probably you. I felt the same thing here in Dallas TX (shout out) . It's been super nice not melting on the bike. First time the weather got cooler here I felt that my riding was getting better. I just thought it was because I could finally wear leathers and "go for it" but maybe you are on to something and the bike DOES like it cooler. I have been told that the 8's seem a bit sluggish when they are cold but nothing a proper warm up couldn't fix. I wonder if I could put an "auto start" on my 8 to get the engine running before I rode her like Seattle Slew. She is my only transportation.


Where in TX you live? I know we got another in Houston on this Forum.

Hey bud, I'm down in Houston (right back at ya)!Yeah you are probably right, it was me! Plus I checked my tire pressure before my ride and it was off by 10 psi; so I'm sure that made a slight difference as well. The temp was absolutley perfect that day; but living in Texas these perfect days are few and far between!

 

I live in bullhead city Az It gets so hot they don't even say how hot it gets.
125 + july and aug.
I do have to say my RC8 does not like the triple digets it gets hot.
I don't ride it much in anything past 105. and I have gear that keeps me cold I just feel bad for the bike.The bike temps get around 200-220 degrees
I like it better when its at 180-190 seems to run better.
One thing it does not like stop and go traffic for very long. bumper to bumper traffic makes it hot real fast you will feel it on your right leg.

 

I totally agree, 180-190 and the bike seems to perfer that temp range! I am paranoid about over-heating any of my bikes so I try to avoid commuting at all and usually only ride back-roads and on weekends when traffic is minimal! Houston has some of the worse traffic in the nation and being on a hot exotic sport bike in the middle of it is not where I want to be.

 

I second that. Dallas traffic is a bi***

I believe that when the bike is colder/colder outside temp it runs richer. for instance the memjet(google it) tells the computer its colder than it really is, thus the computer adds more fuel. not much more, but it does. Now ill wait for ome of the other posters to chime and start flinging poo.

 

That sounds like a very logical explaination. That's where the extra "pep in the step" came from. It's almost like my bike had an extra shot of expresso or something.

 

Extra shot of *petrol

 

when the weather gets colder the air molecules get denser. hence needing a little more fuel for the bang. you notice it more on turbos and a temp around 5c.

 

Damnit i couldnt recall the exact explanation, but yes this is my understanding of it. Thanks sirius

 

wolf your welcome

 

I'm sure it can be adjusted to run leaner for the hotter temp season via tune..

 

Molecules, meemee jets, blah blah blah. ..It's the rider.

I live in South Florida , Recently I went for MV AGUSTA meet at north Georgia took the KTM with me . Weather was most beautiful one can ask for, for a ride in the mountains . Cold in the morning in 60-70F and it eventually wormed up towards the afternoon. I have noticed my bike was backfiring during the cold morning ride. My bike never backfires when riding in Florida. Bike is completely stock .

 

Sounds like the o2 sensors telling the SAS to pump air to burn off the excess gas.

 

I confirm a few things.

I drove mine from 35C down to 7C (95F down to 45F) and I didn't see any change in fuel consumption. Probably very little change but there is certainly one as yes the colder the more O2 molecules per volume of air, which means a little more fuel in. And more air + fuel = more power. Hey, those are the basic principles of forced induction. lolll

Go on a dyno at 125F and then try it at 0F. You'll see. Or just run multiple dynos until the engine overheats. You'll see power dropping.

That thing with turbos at 5C is true, I have a modified car with a turbo and under 8-10C the power increases in a way you can feel the difference (as long as you know the car well enough).

There are usually 2 temp sensors in every engine. 1 for the air intake temp and 1 for the engine temp. The ECU adjusts fueling and timing (if it's a good ECU it'll adjust both) in accordance to the values of the 2 sensors. On my modified car I use a stand alone fuel management system and I have to parm these sensors and adjust them according to my personal tastes if need be, so I can run richer or leaner wherever and whenever I want and yes it makes a difference.
