How do you heat up your carb'ed engine so it starts in cold weather?

[pauly]

Your fat boy is not 117 ccu that is the difference!
I thought you said the starter does not crank the motor over in cold weather.

Paul.

Simply because my FI fat boy is an 01 which is the first year that the fat boy had FI and in cold temps it turns over immediately and no throttling required to keep it idling so I can gear up while the bike warms. No blankets, no heaters, no enrichers, and no throttlling.
If an FI can perform like that in 01 I figure an 08 BDM FI should perform like that as well, unless BDM made their own EFI in house then 08 would be the first year and I'd obviously want to research how those performed.

The solution:
I sprayed starting fluid into the carb, no cigar but closer than before to catching and turning over.
I tried it again with both the starting fluid and this time twisting the throttle whilst depressing the start button.
Lesson learned, contrary to both BDM and online feedback, on my bike the throttle does indeed need to be twisted whilst attempting to start.
Fired right up.
Rode it.
Will never let it sit more than 2 days again.

What's the point on spraying anything into the carb if the motor is not turning over? or am I missreading this?

The fat boy does start in cold weather, 88ci

The motor was trying to turn over, but wasn't catching so it wasn't actually turning over.


Has anyone used one of these to keep the oil warm and hence the engine warm?

Start button wore out on handlebar. Mine did exactly what you are describing (catching as you say) I shimmed the back of the button with some electrical tape and now when hand gets close its starts spinning. It knows what I want

That is for cars or trucks so a lot of it would be sticking out of your oil tank. Even if you could use it to warm the oil it would only be in the tank and not in the crank case.

Bottom line, there is an idio to the bike and you probably found it... and it does not need starting fluid if we know the sequence at the right wrist, right? Right!

This is interesting.

Are you saying that your start button wasn't making sufficient contact to turn the engine over and get it started?
Tonight, without starting fluid, I depressed the start button real good to ensure contact. It fired up and I ran it for about 30 miles on the highway.

Indeed it is. I think I should get one. BTW what is that fallic thing pointing up out of the magnet?

 

[Mr. Wright]

It's either an anal plug or a handle

Yes I would press it, sometimes it wouldn't do anything sometimes it would just bump the starter. Done all the normal stuff - checked battery, cleaned starter post, then someone on here told me about their starter button so i started pressing it hard and it would make contact and turn over, shimmed it up with some electrical tape and has been perfect ever since.

Moroso makes a heating pad that can be adheased onto the engine or a part. They offer a few different sizes. You can put it on a timer so it turns on at a pre-determined time. This will radiate through the aluminum engine and should warm the entire engine.

So this is good and should facilitate startup.

But it really only allows me to start the bike in winter so that I can ride it for the purpose of maintaining it.
The issue of not being able to use the bike as intended still remains. In other words if I stop somewhere for any length of time or overnight, I'd have to have it parked next to power so that the heater can be plugged in. And I also have to carry the heater with me.

Didn't you say you had it worked out? twisting the throttle it fired right up???

Correct. But that's at 30 degrees. Not sure confident I am of it starting in single digits

Otto: Well, it's colder than a witch's tit, my nuts ring like a bell I keep pulling this cord on my crank.
Benz: You need to choke the chicken.

Otto: My chicken lays eggs. I'm not about to choke my chicken yet.
Benz: No, no, the meat and two sides inside your pants.

Otto: An den what?
Benz: An den you think seamen and then rebuild the carb that way.

Otto: Stroke for stroke, oh I get it!
Benz: Right! My balls being low got stuck in the carb and my bike started right up in this cold garage here in the alps.

Otto: You mean twist my meat and have the two sides stuck in the air cleaner side of the carb?
Benz: Duh!

Otto: Or do I twisty titty on the wife till she likes it a certain way she is in foreplay mode like a choke I vision in the future?
Benz: It's all in the wrist counts cause in Otto wise, you're just cranking away to turtleville... as in;

1. Rivet gun.
2. Aluminum flat stock that can be bent to a L shape.
3. Aluminum flat sheet stock.
4. Cutting sheers.
5. Pencil, paper/cardboard.
6. Make a pattern to cover the air cleaner intake track.
7. Have the ability to close off the inlet to zero, or to fully open is a riveted sheet over the air cleaner hole attached by the L bracket.
8. Makes you want to choke the chicken or how to AFRatio my air to fuel inletrick.

Your problem with hard starting in cold weather could be that your primary fluid has gotten thick with the temperature drop and now makes spinning the motor too difficult for the starter. Try heating up your primary with a space heater for about 20 minutes and then give it a crank, I'll bet that it'll fire right up..

Which fluids are you using up there in Canada? just curious.
