Warm Up Charachteristics

The last couple mornings have been a little chilly here, the first since I bought the scoot, so it has been the firstt time I have had to start her up cold. I start it up and if I let it sit there idling and on its own the rpms go up and down. Like it is idling normally then will surge to a faster rev for a few seconds, then back to normal. It seems to do this at a very regular rate and consistently so I am not worried about it and assume that its designed to do this. Just wanted to make sure others worked the same way though.

Yup, that sounds about right! Isn't waiting for your scooter to warm up the longest three minutes, ever?

Warm up? hell i just start it up and go.
but my scooter does the same thing, it will rev up and down.

thanks for the replies guys. Like i said i was pretty sure it was normal but just wanted to make sure. And yeah, I have never waited three minutes either, just long enough to put my helmet and gloves on!

I let it warm up. I REALLY like the idea of having the oil be where it's supposed to be before I make the metal parts start spinning hard...

+1 with a bullet. I grew up with cold blooded motorcycles and still ride one. When you park your bike, gravity brings the oil back into the crankcase. It doesn't hurt to make sure that oil is circulating before you start to stress your engine. Every time I start my bike or scoot, I follow the same routine: fire up the bike, then gear up while it's putting away. The gear up dance gives the bike all it needs to get the juices flowing.

+2. I also hate when I'm in a hurry, and it's still revving high and I have to hold the brake to keep the scooter from rolling forward when I'm stopped.
I just walk out, start her up, then start putting on my helmet, gloves, backpack, etc. Usually by the time I'm done, she's warm, and not so anxious she's trying to runaway without me.

Maybe you guys should add a hand crank to your engines so that you can spin them a bit at low speed to circulate some oil before you actually turn the key. As an added bonus, you'll be getting some exercise!
For me: 1) put on jacket 2) put on helmet 3) put on one glove 4) start scoot 5) put on other glove and close helmet (love my modular!) 6) ride off into the sunset (or sunrise)

That's what the kick start is for. If you really want to be anal and circulate a bit of oil at low speed, kick it over a couple times before hitting the electric start button.
To each his or her own. I'll stick to the warm up routine that's worked for me for many, many years without an engine failure.

Skeeter revs up and down as well.
Another thing you can do while your scoot is warming up is do a quick
pre-ride inspection (check the tires, signals, lights, leaks, brakes, etc) and if it's going to be a long ride do a bit of stretching (your back will thank you). By the time you're done your scooter should be ready to go.
Also, if you haven't already, practice kick starting your scoot.

At cranking speed an oil pump's output is zilch! Get the engine started as quickly as possible to get the oil circulating.

Just the right post for a question i've got.
I understand older engines like shovelheads can distribute oil through the engine before cranking by lightly canking but not starting. Is this not true for the buddys. I'm not sure it matters, it always takes several trys before i can get it cranked anyway, but the sig other suggested it might, so i'm asking.

If you are talking about a lawnmower that doesn't have an oil pump, but only a slinger that throws oil up and around to lubricate - than kicking or cranking will lubricate.
A geared oil pump will not put out much if any at cranking speeds.

Yep, very true about a lot of older bikes...they had a kind of "splash and hope" oiling system. Old Chevy sixes, too. The Buddy has an oil pump and a pressurized oiling system, therefore you must have the engine at idling speed to create the pressure required to actually spray oil.

Not sure what you and Keys are responding to but I'm pretty sure vitaminC's crack about a hand crank was a joke. And I know my crack about using the kick start was a lame joke response joke. Am I missing some other post?

Louie had mentioned an old Harley design and questioned why the buddy engine would be different.
Louie, any engine with an overhead camshaft (the buddy) would need a pressurized oil system to lubricate the cam bearings. A splash oiling system wouldn't cut it.
How long a warm up?

Err on the side of caution. Start the engine up the night before.

I was really asking if this (see quote above) is helpful when it's extra cold (not an issue for many months to come). It sounds like keys and jgalar are saying kicking without starting doesn't lubricate an engine with overhead cam by just a turn of the cylinder/a kick without a start. ? Sh_t I don't know enough about what i'm talking about to ask the question.
I'm not too worried about hurting The Bud he seems to have good technologie.
Keys..."splash and hope"? Is that why all those old bikes drip oil and the proud owners call it "well lubed"?
