carb cleaning

Ive had the bike(2003 V Star Classic) for 3 weeks now and still is not running right. Takes a few tries to get started even with choke on and the will spit and sputter after it warms up unless I give it more than 1/2 throttle. Been through 3 tanks of gas 2 with 1/2 bottle pof seafoam and the first one my brother in law used some kind of injector cleaner. Dosent seem to be getting any better. I attempted to take it out yesterday but got as far as taking the air box off and noticed the rear carb boot wasent connected. I thought this could be the problem ,so I put it back together and try it out. Still had the same problem. So sunday Im gonna take the carb out and give it a good cleaning and clear out the jets. Got a print out on how to get to the jets and picked up a set of needle nose vise grips. The replacement screws that I picked were not stainless steel. Dose anyone now if this is a bad idea not using stainless alan head screws? wish me luck

I bought a 650 custom about 3 mo. ago. Very similar situation the bike had been sitting for sometime. I has lots of trouble getting the bike to idle well and she would run on the front cylinder 10 min into a ride. I had the carbs cleaned and now the bike runs great. Don't give up on the 650 it is a great bike and once you get the gunk out of the carbs she will likely run great. Mine is running great and I just love it!

I have the 1100 classic. I know it still is the same problem but you can get to the bowls easier. My dad has a 1999 650 .

Well I got the carbs off. Opened the the bowls without messing up any of the screws. Looked like it was off before because the pms screw plugs were already out. Took the jets out (main and pilot) let them soak in some carb cleaner(CRC). Everything looked clean but sprayed out the bowls and all the jet opening. Used a small wire from bread twist tie to go through the small holes and the pilot opening. Put everything back together and fired it up. Still hard to start and still stumbling when I try to take off unless I give it more throttle. Anyone have any sugestions? Was realy hoping this was gonna fix it.

I had similar problems. Have you looked at some of the simpler fixes? Spark plugs properly gapped, new fuel filter?

I forgot to mention all the stuff I did so far. Changed the oil, new spark plugs, new fuel filter. Checked the petcock filter when I had the tank off.

Have you done a carb sync, if they are out enough the bike will run real bad.
