I want to know if its better to let your bike idle to warm it up and how long? Or if it's better to start it, put it in gear and keeps the revs down til its warm. I'm just coming off a piece of crap BMW, and they don't want you to idle it to warm it up. Thanks Guys...

My process,
1. Start bike and let idle while I complete steps 2 to 4.
2. Put on helmet
3. Put on gloves (jacket first if it is cold out)
4. Get on bike and walk backwards out of garage
5. If it has not dropped down to Idle RPMs (about 900) wait until it does (generally not to long if it has not already)
6. Idle in first/second out and down 1/2mile of dirt road. Once I reach the highway it has generally been 5+ minutes sice I started it.

Then I haul A$$ until 3rd which is where I reach 60-65 I double shift to 5th and cruise.

I love acceleration but care nothing for top end riding, plus it keeps me from getting a ticket.

Its an aluminum Engine. Definitely let it warm up. Aluminum expands and contracts more than steel with temperature. Parts of the motor like the piston and head will get hotter quicker than the walls and other parts. If you stress the motor during those conditions, it can cause damage.

BMW M5 cars have a redline indicator on their tachometer that change and extend the limit as the engine warms up. When dead cold, the readline is 3500RPM, as it warms up, it gradually goes to 6600RPM.

Let it warm...

I hear you Dark. I just get on the saddle and once my ass is warm, that means the engine is warm. If I need twarm it up faster I just fart a couple of times to speed things up. Becareful though, I have ended up with some sacraficial underwares before !!! I guess thats when the engine is too hot from idling too long. Hope this helps !!!

When I was rebuilding my 360 motor, there was a graph in my rebuild manual that showed engine wear vs temp. The lower the temp, the more wear.
Maybe this will help a little.
I do somewhat the same thing as BigBlack, except no dirt road, but still the same idea.[/emoticons/emotion-1.gif]
