    I just bought a 2000 vstar 1100 w/3000 miles from a reputable dealer. They can't get it running right. Have removed & cleaned carbs & synced them, replaced a couple parts, replaced intake gaskets and is better but still not right. When starting out sometimes it falls flat with no power until rpm's come up and occasionally will stall completely. Can remedy by setting the idle too high (no tach, but about 1100-1200 rpm) but that's annoying too. They've had it 3 times now but it's not right. Any ideas?

    First off welcome to the forum. When you get a sec, please do an intro in the welcome section.

    1150 to 1250 is what the idle should be set for. It's not a Harley and will never sound exactly like one. It is supposed to idle at a higher rate. That may be your problem.

    put 1/3 of a can of seafoam in the gas tank......get on the freeway and run the bike hard for 20 miles or so....that may just solve the problem.....you have a bike thats 9 years old with very few miles....it sat around doing nothing for a long time....bob

    poppj,
    the man said the dealer removed and cleaned the carbs so the seafoam trick i doubt will work.

    i wonder if they checked the coils?could be not enough spark,this would make it fall on its face too.since they done the carb thing i,m thinking not enough spark.or not enough juice.....did they check that stator output?

    crank slow when starting?

    more info please.

    try changing the sparks plugs too...this worked for another rider who had a similar issue.

    I'd start by draining the fuel tank and checking it for internal damage (rust). There's no telling how bad the gas is in the tank. Also, a new fuel filter would be a good idea, and a fresh set of spark plugs wouldn't hurt.

    With that little mileage on a bike that old, you may find that none of this easy stuff helps. If that is the case, you may end up having to completely disassemble the carbs and soak them in chemical solvent overnight. Then, wash them thoroughly with good carb cleaner (Berkible 2+2 or similar) and blow everything out with compressed air. Don't forget to reset your float levels when you put it all back together. EDIT - By the way, I say this because I have my doubts that the dealer did a thorough carb cleaning. They often pull the float bowls, spray the bottom of the carbs with cleaner, and say they "cleaned the carbs". This is not always enough - especially on a bike that sat around so much - EDIT

    The carb diaphragms and other rubber parts are probably okay, but I would bet money that there is still a bunch of crap gummed up in the carbs and jets. Once you know the carbs are REALLY clean, replace all the jets and maybe even the needles with new - the originals are probably pitted badly inside (where you really can't see). I say this from having a similar experience with my wife's bike (that only sat about two years) and knowing what I had to do to get it running right.

    Of course, I don't think that YOU should be responsible for any of this and, if all this sounds like gibberish to you, I would suggest that you take the bike back to the dealer again. All this stuff can be corrected for relatively little money so, in my opinion, that dealer should make the bike run the way it is supposed to. That is, unless you specifically agreed to buy it "as is" and got a better sale price in return. The only real cost to the dealer is the labor to do all the work I describe above. That would be expensive if you were to pay them for it, but it costs them relatively little and any shop worth a dime should make this right for you. I've had very bad experiences with my dealer, though, so I hope yours is better. If all else fails, there are a lot of people here who will help you get your bike runnning right again. The V-Star 1100 is an exellent motorcycle and I think you will like it very much once you get all this sorted out.

    Good luck, and welcome to the forums.

    Does it have stock Yamaha pipes and air intake?

    I agree with PG Man that it sounds like a fuel issue. (I'm assuming you've checked/changed the spark plugs). You could pull out a plug to see what it looks like. Black electrode = running too rich - white electrode = running too lean.

    Adding a bit of that "Seafoam" stuff would not be a bad idea. It'll do a good job of cleaning out the entire fuel system.

    Also check to make sure the fuel filter isn't plugged. I'd even go so far as to drain the gas tank and pull out the fuel valve on the bottom of the tank. It has a fine mesh screen over the 2 fuel ports and could also be partially plugged.

    You may even suggest these things to the dealer..... I'm sure they want your bike running right too.

    Well if I bought a used bike the first thing I would do if I had power issues would be to pull the main and pilot jets and double check the numbers on them. The main jets will have the sizes stamped on the face and the pilots on the sides. It is entirely conceivable that whoever had it before you had modified the bike with either pipes and/or intake and could have done some jet changing to get it to run correctly, then put back on the stock parts without jetting back to stock. I would pull the plugs and replace them as well. I wouldn't pay too much attention to what the color of the plugs are because if the dealer ran cleaner through it it could affect the color of the plugs, which could otherwise be a good indicator of wrong sized jetting. If I had to take a guess without ever seeing the bike I bet you have larger pilot jets in it than a stock bike should have.
    Just for my opinion, I wouldn't say that Yamaha fell on their face, I would say your dealer has. These bikes are generally pretty bullet proof.

    Thanks for all the replies. I believe it's all stock. Had them do the plugs the 2nd time it was back. I've put about 1200 miles on which is 8-10 tanks with carb cleaner in 3 or 4 of them. The problem is very random and I can't pattern when it will happen. I think the problem is in the back cylinder only cause the top exhaust is where you can hear it. There is crossover in the pipes but it still is worse in the top pipe/back cylinder. It's at the shop again after a mixed weekend of sometimes good sometimes bad and he's thinking maybe a sticky float. They're still footing the bill so it's not all bad. YASZ970, why the money back, have you been through something similar. Am seriously considering trading up if it's not fixed this time. Thanks again am very impressed with the site and the common joy of cycling.

    My bike was doing the same thing. I knew the carbs were dirty. When I changed to the MaxAir Pred pro kit, I cleaned the carbs good. They were varnished bad from sitting around for long periods of time. I changed both diaphragms because one of them was actually bad and I figured I might as well change the other at the same time. My point is that just because it's the dealer doesn't mean they know what they are doing. Like bkman said they could have half arsed it when the "cleaned" it. If they are Yamaha dealers and they are sure it's the carbs, you may ask them to replace it with a new one. At worse, you should at least be able to get your money back.

    the worst thing for a motorcycle is to let it sit month after month after month without riding it....if you have a 2000 motorcycle with only 3000 miles its been sitting around to long....bob

    The thing is that it is a 2000 from your first reply. This means it is over 10 years old. With only 3K miles on it, there could be any number of issues. The dealers have many bikes come through their doors every day. Just because they say they cleaned the carbs does not mean that they actually checked the numbers on the jets (you can't tell from just looking at them) nor does it mean that they pulled the jets out of the carbs and properly cleaned them. Just because the outward appearance is stock doesn't mean anything as far as internal configuration goes. I have saved everything that is from the stock configuration on my bike, so in a matter of hours I can have it back to exactly the way it was when it rolled off the floor. However, unless I were to take the time to jet the carbs back to the way they were, the next guy to get that bike would be in for a real interesting time! The previous owner could have adjusted the floats without really knowing what they were doing also. There are a lot of things that someone could do to a carb to screw it up., An I've seen some of the instructions from different companies (no, not going to bash anyone in particular) that tell you to rejet and give some half-a$$ed settings that don't even work properly with their product, let alone if you pulled the product off! Jets are cheap. Ask the dealer to just replace the mains and the pilots with new. I can get a pair of Mikuni jets for like $5.00 so I'm sure the dealer cost is way less than that. Oh, and to make matters worse, I read on a forum the other day (can't remember which one) where someone actually took stock jets and drilled them to "approximately XXX" whatever the size was he was after. So even the numbers might not mean anything. 10 years is a long time to have a bike and only put 3K on it. I have to wonder how badly this guy messed it up so that he didn't even want to ride it!

    my comment was not to be funny. i was involved with a ford mini van lemon law at one time.you said you just bought the bike.to have it back at the shop numerous times is a real pain in the azz.i ride everyday other then snow and rain.i would be really pissed if the bike i bought doesnt run properly.
    its nice you are not paying for repairs,but you are not riding either after you shelled out the money.some have more patience then others,and unfortunatley i dont have any.
    the ford problem was after the lemon law kicked in and we got a fully loaded eddie baurer model for the same price as the plain jane one we had was they put in 2 different motor mounts,which led the motor to be crooked,which made the tranny not right.

    I am new here,and i am off topic but my husband bought a 2008 V-Star Silverado Classic right out of the crate This is his baby and he had the bike in at 800 miles for the routine maintenance. Just shy of 4000 a rocker noise started and decided to have dealer look at it. We couldn't believe their attitude : "It is not a bad noise and won't do any damage", and they gave it the 4000mile check and told us that they couldn't find anything when we questioned them they stated "as the bike gets more mileage the engine is going to make more noise". The noise is loud and I believe they did not adjust the valve correctly or checked the rocker arms. Anyone else have this problem? Thinking it taking it to a different dealer though a little gun shy. We live in Washington. My 650cc V-Star is a 02 and has over 9000 and it doesn't make half the noise. Husband is concern! Any suggestions? Can here him coming down the street. The clacking noise is so loud.

    Feeling the extended warrenty was hogwash!

    If you can hear the clacking noise when he is coming down the street i would get it to another dealership very soon....it is true all of these 1100 make some ticking noise....a good full synthetic oil stops most of the noise....someone who works on these bikes everyday can listen to the noise and know if something is wrong .....i dont like dealerships much either....bob

    bogejoltman,

    I had a honda 1100 with low miles and had almost the same problem. I had it in the shop multiple times and thought the problem was in the fuel system. I found out later, (after I traded) that the problem was actually in the electrical system. The stator (sp?) was about to go out. After I traded the bike, it did just that. The guy who bought it after my trade rode it home and then couldn't get it to start at all. If the fuel system has been gone through and they still can't find the problem, you may have them look at the electrical system. Just a thought. I hope you get it fixed.

    Wondering if bogejoltman found out anything?????? Please let us know if you did!

    It turned out to be a wrong size needle on the float of the back carb. It was letting gas through and flooding the cylinder at an idle. That was the 2nd part they replaced that was wrong. Makes me think someone was messing with it although the pipes don't look like they were taken off any time recently. We rode about 200 miles Saturday and it ran well. Six of the eight bikes we were with were harleys, so the next problem is to make my vstar loud enough so I can hear it running in the crowd!!
    Thanks for all your help, it's nice to know there are people out there who care!!!

    Was this work done at a Yamaha dealer? The stock jets are 2 different sizes. That should have been caught the first time. Well at least they got it figured out for you. The good news is there are lot's of pipes to choose from for this bike so you should find something you like.

    Thanks guys. I think he will let me take him to another dealership. So far the bike has been great. It is his baby her name is "windy" black and shiny.
    I will let you know about the outcome. I am considering upgrading to a V-Star 900?cc. I want to be able to keep up with hubby especially when he decided to leave me in the dirt as his 1100 pulls smoothly away from my 650 well lets just say its not a warm and fuzzing feeling. lol
