Sorry about this boring question,but i'am new to Harleys and don't know who else to ask.

CD made a comment on my other EVO thread about "observing proper warm up procedurers" What is the proper procedure.

How long should i let it warm up?

Is this done strictly at a idle?

Is this done at low RPM on the road?

How will i know when its warmed up?


Thank! in advance for any help.

Put the engine in a preheated over @ 350 degrees. Then, uh wait wrong thread. I believe and I may be wrong but when you pull out your enrichener, as your bike warms up and the engine does not need additional fuel to air ratio of mixture your bike is warming or considered warm. I would recommend buying through direct parts a temp gauge for your oil cap. If your concerned.
I always "try" to let my 05 FXSTI warm up. I think it has an aluminum block that could suffer some set backs if I try to get up and go when it is cold. Especially at the seals.
I hope someone else can add something I am not a wrencher and may be totally wacked except for the cooking thing.

I've got a 94 Dyna w/ the Evo. Pretty standardly during warm weather season, I start the bike w/ the enrichener fully extended. As soon as I can get it to idle, I set the enrichener back to half staff. It'll stay there for a couple of minutes while I gear up. By the time I'm done prepping myself for the road, I kill the enrichener, hop on, and go. All a process of about 5+ or - minutes. Cold weather....extend the time. Look at it this way, the colder it gets, the more gear to put on.....get it?

EVO's and TC88's should be treated the same IMHO. Granted, you can fire up an EFI bike and ride off, but it is pretty hard on the engine.

I start the bike and let it idle until I can feel some heat in the rocker boxes. This usually only takes a few minutes. As BikerJim1 sez, by the time you have all your gear on, it should be warm enough. Take it easy the first few miles until the engine is fully warmed up. If you do this on an EVO, you can pretty much eliminate probably 75% of the cause of base gasket leakage.

A note on carbed bikes: There is a huge tendency to over size the pilot (slow speed) jet. I have worked on bikes that dead cold did not need the enrichener to start. The pipes would be black and whacking the throttle would send out a blast of black smoke. Pulling the bowl I would find anywhere from a #48 to a #54 pilot on bikes that were relatively stock and at 2500 ft. That is serious over jetting. You can easily foul the plugs and I can guarantee you cannot pass the EPA idle exhaust test. On a dead cold start, you should always need to use the enrichener. Even down here in the summer, a few seconds should be needed. In a cold climate, you may need full enrichener for a few minutes. A properly setup slow speed / pilot jet circuit gives a crisper throttle response, better mileage and better transition to the main circuit.

Jim, That's not even a consideration. Been in the single digits all week here in central Washington. Get's way up to about 15 during the day time.

Bike's in the garage where its going to say for awhile.
