possible carb issue 4 Years, 9 Months ago  
Hello all. I recently bought a used 2004 roadstar xv1700. I am having an issue with the bike. When starting the bike, I turn on full choke. It starts up fine. After a couple minutes I switch to half choke. It still runs fine at this point. However, if I turn off the choke, the bike idles rough and threatens to stall and sometimes does stall. Based kn the symptoms, I first checked the air filter. The prior owner apparently hadnt replaced it in quite some time. I switched out the old filter with a k&n. The bike still exhibits the same symptoms. I am thinking the bike may need some carb work based upon these symptoms with the choke. I would appreciate others feedback as I am a pretty novice mechanic thanks

No you don't need carb work these bikes need to be warmed up. You are doing what you need to do when you crank it up but you should take off and ride it a mile or two before you turn the choke all the way off. Keep it at half choke for the mile or two then push it in. Also make sure your idle speed is around 900 rpm to keep proper oil pressure at idle. BTW

Re:possible carb issue 4 Years, 9 Months ago  
You may not have a problem. As was already stated, let the bike fully warm up. Turn the idle up a little try a half a turn. It's the black knob on the right side of the engine below the air cleaner @ the bottom of the "V". If you can't wait (like me) leave the choke on 'til you are out of the neighbor hood about 1.5 miles for me then push the choke in. Take it for a ride & the idle speed should really be set when the bike is fully warmed up. A lot of people have their idle set too low. It sounds cool, but... well that's about it, it sounds cool.

Now, after you set the idle up a little bit if you are still having problems make another post with the symptoms and someone will be along to help.

in the colder mornings sometimes I still have to keep mine at have choke for a little bit and then quarter choke for a few more miles until she is good and warm. Once summer gets here you won't have to leave the choke out as long. Make sure she is good and warm, also let her idol for an extra minute before taking off.

Follow the starting advice given, and also pick up a can of Seafoam(or Techron, etc. Autozones, Oreilly's, and Napa will usually have the Seafoam), and dump about half(8 ounces) in a full tank of gas, and go for a ride. It's common for used bikes to have been sitting, and the pilot circuits can get gummed up pretty easy on the Roadies, when the bike sits, and nobody used a fuel stabilizer in the gas when they shut it down for the winter. A good slug of Seafoam, will often help. Run an ounce or two in the gas on a regular basis, and it'll help keep things clean in the tank and carb.
If, none of the advice helps, then you may need to think about some work on the carb.

I was having the same problem. I blame it on the gas we get up here in Montana during the winter, they put ethanol in it. I put a half a can of seafoam in and kept the choke on for a couple of mile and she seems to be running just fine. Luckily I have found a gas station that doesn't use ethanol and I will be filling up there from now on.
