\ From the radiator, through the case and out
the exhaust. If it has to do with the cooling,
engine or exhaust, discuss it here!

Question How long to warm up the engine before starting out.

The manual says to warm up the engine for 2-3 minutes before moving,
and also to warm up for 2-3 minutes again when the engine has
been stopped, no matter for how long.

Are these procedures, especially the one that wants a warm engine
to be warmed up again when after being shut off...no matter for how
long to be followed after the engine has several thousand miles on it?

BTW, When I changed the oil for the first time in my VN750 at 230 miles
it didn't look dirty at all, but I just did my first oil change on my KLR650
and the oil had many, many very small minute particles that made the oil
look somewhat like dirty dishwater. I broke both engines in the same way
and can't figure out what caused the difference unless the KLR650 had
closer tolerances?

At 6:00 AM, going to work, I usually warm up for 2 minutes. Trying to be nice to the neighbors.

here is a trick i use.... i hold just a little throttle when starting and keep it at about 1500 rpm....and hold it. as the engine warms the rpms jump, that jump indicates to me the oil has circulated and is warm. just 2-3 mins in summer almost 5 mins in winter

That's pretty much what I do, but I just use the choke to keep the RPM's up.

Believe it or not.I asked the dealer that guestion.He told me all that engine needs is a 30 second warm up.I don't follow that I usually go about 2 minutes.This dealership is a small father and son shop they do both sell and work on bikes you have to get one of them out of the shop if you want to see a bike.I figure he would know what he is talking about being a mechanic.

Here is my morning routine. 35 deg or 100 deg, always works the same. Choke on full. Key on. Clutch in. Hit the starter button. About a 1 second cough. Hit the button again and it roars to life. Immediatly start reducing choke. I keep it between 1000 and 1500 rpm (limit the early morning noise for the neighbors). When it runs stable at 1000 rpm I go get the helmet and gloves from the garage. When I get back to the bike I leave. 100 yards to the state highway. As I pull onto the highway the choke gets turned off.

There's been a few times I'd forget to completely turn the choke off. I'd be motorin' down the road and wonder why my bike is runnin' like crap. Then I realize, Duh, chokes on dummy !! Shut it off and all's fine. I hate when I do that.

i use full choke, hit start with the very slightest blip of the throttle and she fires right up each time. i then adjust the choke to keep it between 2000 and 3000 rpms for a coupel minutes. usually good to go after that. starting back up after stopping i usually let it warm up for 30 secs to 1 min unless it was a very quick break in riding.
