I am thinking that your drips are due to too much oil. Lower the oil level in the sight glass to about half or little less than half.

I believe that a short might cause your situation, or the alternator/generator are sucking the juice out of your battery, causing it to weaken faster than normal. What's the time limit for the battery failing relatively quick?

Oil in the breather box is totally normal for the 1100 V Star. The dealer says they make an after market baffle to be fitted in the box to prevent this problem. The baffle itself directs the crank case blow-by directly into the manifold to be re-burned. I believe, if the engine had a P.C.V. system, it wouldn't have this problem to begin with. A simple P.C.V. system would make it run better and improve emissions.

V-Star Custom 1100 2004

Hi, already wrote some comments about heavy vibrations. I have the same problem. Heavy vibration starting at 50 mph, and it gets worse at higher speeds. It's not a tire balance problem, because I pull the clutch and it sleeps..

It all started when I changed the rear tire.. I'm lost on this one.. I've had it checked by the dealer.. they have no clue..

I don't enjoy the bike as I used to, since that vibration problem.

Have you found the problem on yours?

That noise you can here is the electric fuel pump; perfectly normal. It stops once the carb float bowls are primed.

I have a 2003 1100, and when I first got it, I felt the same thing. The dealer told me when the motor is over 3500 RPM, you feel it due to it being a solid mount. I just got used it.

If you change the pipe, you must re-jet the carbs. I did not, and at 18,000 I'm having valve problems!!!

Had the same thing happen, and when I looked into it, got this info off the net.

There is a too-narrow oil passage that relates to the sensor that can cause a false low oil pressure signal. Apparently the 1100 V-Star has always been this way, and probably always will be.

My guess is that Yamaha sees this as a minor nuisance, and to open the passage is not worth their effort.

In two years this has happened to me twice.

Do you have the name of forward control company? I need those (254-537-2002). Thanks.

Over filled with oil.

Hi, I haven't had any comments on that bad vibration problem at high RPM. Did you find what was the problem? Mine is the same..

I just wanted to respond to the post on the V Star 1100 in regard to ticking after adding the Hyper-exhaust. As I have had mechanics tell me, the valves are noisy, but I have found the butterfly flaps are making the ticking sound, which is sometimes confused with valve ticking. Once they realized this, they have all agreed.

Hi. I am John. I just bought a 04 Yamaha V-Star 1100, and can't pass emissions because it's putting too much gas out when driving. What do I need to do to reduce the problem that I am having, so it can pass emissions?

Put a full face helmet on and the noises disappear.

My brother and I just bought a 1100 V-Star 2005 and had it serviced to the tune of $1300, and after we got it back, it ran good for a few days, then it went downhill fast. Fuel mileage was cut in half and it stalls constantly. Every shop is busy for 3 weeks, so I found a shop that would look at it. The rear carb intake was filled with gas!!! Any ideas as to why this would happen?

The guy who did the "tune up" only cleaned the carbs and intake. Found a bit of oil in the air box.

This bike only has 4000 km on it. Help!!!

27th Jul 2014, 20:39

You overfilled the oil level.

28th Sep 2014, 15:18

Had the same trouble with mine. I removed the float switch and cleaned it. Fixed it... for a while. Common with the Star. Just keep a check on the oil.

29th Sep 2014, 23:48

It is the fuel pump.

I have a 2004 V Star 1100. I have had to change the clutch gear twice now in the last 6 months. I am really easy on my starts with this bike, but am now wondering why the spline keeps wearing out on the wheel side. The bike now has 30,000 miles on it and runs great.

16th May 2015, 06:17

I most recently have experienced the same issue. What did you find out?

7th Jun 2015, 14:23

I have an 07 Custom 1100 and have recently noticed that the check engine light comes on while I am riding. It only stays on for a minute or so, then goes off. I have shut the bike down and powered it up to see if it throws a code. The bike runs normal. I have talked to a mechanic, and he said unless it flashes a code or the light stays on all the time, there is not much he can do. Anyone else have this problem, and what did you do to resolve it?

You are going to absolutely love that Mustang Seat - BGT.

The carb float needle and seat are probably bad or it has dirt on the seat. I had the same problem, and a new needle and seat fixed it.

This has happened to me since the day I bought my 1999 V Star 1100. It happens every time I ride within 30 minutes... It goes on and off throughout long rides. I've brought it in every season since I bought it for regular maintenance and relayed this to the dealer... It clearly doesn't have a "fix". I know I'm good and can ignore it as I check the level before every ride.

Hi, if you have a serious drive line vibration in the V Stars, you need to check the nut that holds the u-joint yoke onto the output shaft of the transmission; they have a reputation for coming loose and can trash your motor if they do. Google mid drive shaft vibration and you should see some comments and info on it.

19th Mar 2017, 20:57

If your oil light comes on, just add a little bit of oil. The light is controlled by a float.

30th Jul 2017, 12:35

To those complaining about vibrations, check to make sure that the carbs are synchronized correctly. That will drastically smooth it out big time.

I agree, enjoy the ride. I prefer being on two wheels versus 4 wheels.
