Do what was said, when it start bogging or bucking, reach down with your left hand a pull the choke until the bucking stops. These bikes do NOT like cold weather. Seafoam is a fuel system treatment that can be bought at Napa Or Walmart or most parts stores.

I have an '02 and here is what I do for my bike in cooler weather.

Cold Start: Fuel Enricher (choke) - first notch, crank throttle twice, hit the starter. Let it idle while I glove up, helmet, etc. (approx 2 minutes).

I then ride with the choke out until it actually starts to bog on starts (usually 5 to 10 minutes depending on temp). Then I push the choke in and everything is fine.

Warm Start, in cooler weather - Choke out first notch, crank throttle twice, start, ride until it starts bogging a little on starts and push choke in.

I have noticed that in cooler weather I just leave the choke out and when at a cruising speed it will start to surge/stutter, at that point I will push the choke in and everything is fine.

Some of this will vary from bike to bike I am sure, that's just the way stuff is!

Thanks, what does re-jet mean?

Inside your V-Twin enigine is small jet engine motor. Since you bike is older (like mine) and not fuel injected you need to update the jets to the newer model, like the ones used on the F-22 Raptor for example.

Wouldn't that be cool....that might be a bit large to fit between my legs. But I do get the point.

Kevin:

Inside of the carburetor, are several brass or bronze orfices, which can be changed to achieve either larger or smaller sized openings in the "jet".
Through these orfices, fuel rapidly meters from the bowl into the main carburetor opening, where it becomes atomized, and then sucked into the intake port of the motor.

Barometric & temperature changes can affect the motor's demand for atomized fuel/air, and recalculating/replacing the carburetor orfices or "jets", is the method used to help the motor run at peak, at all times during the year.

Here's a guide from the Jets, Injectors, Pipes Forum:
Rejetting Matrix

Here's a jet location shown on a Harley carburetor:

I read the rejetting matrix thread last night. I have to ask the previous owner what if anythign he did when he added the K&N air filter and/or if he knows the jet sizes. I think the pipes are stock, so I don't know what impact that might have if it is now getting different air flow than originally designed.

I rode to work today, 30 miles at 37 degrees, highway speed, with the choke set on the first notch. The bike ran great. If I put the choke in, it started to run rough. So for now I will just keep the choke open a bit. I appreciate all the comments.

If you are running a K&N without a rejet and with stock pipes. Take the K&N off and put a stock filter on and you will be fine. These bikes are lean to begin with and a K&N just leans it out that much more.
