Not sure if others have expericed the unexpected, yet awsome effect of the cooler Northern weather (52 degress on way to work) on the HP and performance of the FJR.

First occured dropping from 3rd the 2nd gear (high revs) - then twisting throttle full open for a quick run

Next was a quick pull away from a traffic light.

I'm not talking stunt wheelies-I'm talking the, "Oh shit the wheels come up wheelies."

Now tonight I spun the back tire while making a tight/quick accleration turn coming out of a gas station.

Oh-it's and it's an AE model I'm riding.

Tell me I'm not alone.

 
Basically, cold air is denser air which allows more fuel to be burned which = more power. Drag times will always be faster in proportion to colder air, until a cold track and cold tires reduce traction.

The colder fall weather (and even colder winter weather) always adds zip to my motorcycles performance.

 
Stew,

I have an 06AE. If you haven't had the bike that long, With time you will learn how to work the throttle.

If you're lifting the front wheel, you might be hitting it a little too hard! :rolleyes:

 
Last night rode from 91 to 73 degrees within 5 miles all at the same altitude and the difference in power is just in your face obvious. Cant wait for Az winter, 60s just about every day! :yahoo:

 
Tell me I'm not alone.
Your not alone, cold and humid weather = very happy engines. Theirs much to be said for the denser air, and the moisture content smoothes out combustion. Every vehicle I've ever owned ('cept one dodge that would stall if you pissed in front of it) loved that combo.

To hard sounds almost perfect.

I have not had much of a chance to find out how mine runs in warm weather since it has been such a cool short summer here.

 
I don't know how 'Northern' you are but be careful about accelerating hard in a corner as it starts to get a little cooler. If your tires aren't up to temp, the road tends to be cooler this time of year and your grip isn't as good as in June-Aug.

I found this out the hard way. I got off work and while making a right turn to get on the onramp for the interstate I opened it up to get up to speed and the back tire broke traction kicking out while still in the lean. Lucky for me I didn't high side.

Your tires could have been up to temp. If so then I would think your tire pressure and/or road grime might have contributed to the tire spin.

+1 I do love the cooler weather for performance.

 
52 degrees! 49 degrees!

What the hell? It's only September!

It was awesome this morning here, too! Down below 80! Had a lovely ride to work!!!!!

 
I checked the tire pressure and both were at spec. I may have picked up some oily residue in the gas station berfore pulling out. (a new-remember this one thought) I work for a company that makes engines (even superdharged prodcut with Intercoolers) and realize the cooler temps will allow the engine to take in more/condensed air, but I am still amazed at the dramatic differnce the rider experinces. It's like owning a second bike-an evil twin bike almost. Making me really look forward to my October rides.

 
I really like how hard my nipples get but then theres the runny nose into the 'stache....Oh and the bike loves it..especially the asphalt they use down here..I frequently light 'em up in 2nd and a little curve... and the Michelins are waaay better at this than the Avons were....keeps the tailgaters back anyway..C'mon November !

Blessings,

Bobby
