Warming up the Harley
How long do you guys usually warm up urbikes? One of the Harley Techs told me that we are supposed to warm up until the rocker heads are warm-hot then its ready to go. and Never ride when its cold. It usually took me 5 mins for the bike to warm up. They said the purpose of this warming up is to swell up the bore and pistions to allow the oil to roam inside the engine. Without warm up, the piston will scratch the bore and damage the engine. Correct me if I'm wrong.I would like to hear your input about this - true or false and why. thanks!

RE: Warming up the Harley
I asked my wife to "warm up the Harley" last night. It didn't work.
I just usually wait 30 secs or so, then ride off easy.
Oops. In my quest to be glib, I didn't see the last part of yur post. Scratch the cylinder walls?
Nonsense.
On a watercooler with Alu pistons and Nikasil bores, you might need a little warm-up time to avoid a cold-sieze. That ain't us.

RE: Warming up the Harley
I agree with the Tech, if you get after it too soon the piston can expand faster than the jug causing damage. Some of my friends fire it up and take off but I usually let it idle for a while. I knew a guy who seized a fairly new 2 stroke because he didnt worm it up.

RE: Warming up the Harley
It may be unfortunately for my motor but I generally wait a total of 10 to 15 seconds from the time I start the motortill I go - on my EFI bikes I just wait for the RPM's to setting down to idle and go. I've have never believed in "warming up" a motor - don't do it in my car, don't do it on my bikes.

I do exactly what the tech told you...... usually takes 5-7 min. My motor's an EVO though, and from what I've read, there a little more pickey about warm-up than the new twinkies.

RE: Warming up the Harley
I just let it idle while i'm gettin my gear on. What usually happens, as soon as I get my gloves on and am ready to go, my cell will ring. Off comes the gloves, etc, dig out the phone and it will be my riding bud wondering why I am late.[:@]
By then 5-10 mins has passed and the bike is all warmed up!

RE: Warming up the Harley
Hmmm seeing how they go from 0-240 degrees in about 1 minute I would say 1 minute is plenty long enough.
