Question about 2001 Yamaha V Star 1100 Classic

1 Answer

I have a 2001 Yamaha 1100 v-star. It has carb work and pipes on it. Runs good at idle but at about 1800-2400 rpms the bike starts to brake up while holding the throttle with a steady load.

Hi, Lamotorsport and the usual suspects are:
1. Severely discharged or a damaged battery, should have 12.5 volts or better and be able to pass a load test if necessary.
2. Check battery terminals for damage or corrosion, check the battery cables at "BOTH" ends for loose, corroded, or broken connectors, "INSIDE" and outside the cable harness, perform connector wiggle test and check cables with an ohmmeter if necessary.
3. Spark plugs in bad condition or partially fouled.
4. Spark plug cables in bad condition and leaking.
5. Spark plug gap too close or too wide.
6. Faulty ignition coil, module, and or sensor.
7. Loose, dirty, or corroded ignition module connector at crankcase.
8. Faulty CKP or CMP, MAP, ETS, ATS, TPS, O2 sensor.
9. Intake air leak.
10. Water, dirt, or rust in the fuel system, carburetor and/or filter.
11. Fuel tank vent system plugged or carburetor vent line closed off.
12. Vacuum line from intake manifold to fuel valve is broken, cracked, pinched, or missing.
13. Carburetor controls misadjusted.
14. Damaged carburetor.
15. Incorrect valve timing.
16. Weak or broken valve springs.
17. Damaged intake or exhaust valve.

SOURCE: engine backfire

try pulling the choke out a little and see if that doesn't help.  If it does that is a sign that you are running too lean and need the jets in the carb increased or just the air mixture screw adjusted.  If the coke test doesn't help, please tell me more about how and when it acts up. Like after the motor is warmed up does the backfiring quit?

SOURCE: where is the oil filter on my yamaha V-star 1100

On the right side of the bike (right side when ou are sitting on it) just above the rear brake lever behind a small circular plate. remove the plate and the oil filter is inside (you will easily see it). Warning---on these bikes you have to drop the front exhaust header and right floor board in order to change the oil filter unless you install a after market oil filter relocation kit. If you plan on changing your own oil it is highly recommended to install this relocation kit.

SOURCE: 1980 Yamaha XS 1100 Carduretor diagram

It is part of a detent mechanism for the choke. No, all 4 carbs do not have them, only 1.
Here is a link to Yamaha's website, where you can pull up a diagram of your bike's carbs. The ball is #10 and there is also a spring with it.
http://www.yamaha-motor.com/sport/parts/home.aspx
They are saying there are 2 balls and 2 springs, but I do not remember them having 2. I also don't see another #10 or #11 on the picture anywhere. You should be able to look at the rod that connects all the chokes together and see if there are 2 sets of dimples for the balls. Obviously there will be one set in carb #1, if you find another set of dimples for a detent ball, then there indeed would be 2. Also, the carb body would be drilled for the spring and ball like the #1 carb is.
Thanks

These parts are fairly reliable. Rather than buying new, you should be able to pick one up from a motorcycle breaker who will post it to you. I would expect to pay about £60-£100 tops in the UK (Depending on mileage). ANy Yamaha dealer will be happy to order you one new, but they are a hell of a price!

There is no need to run anything other than regular gas in the bike, the extra octane only makes the VMax engines run hotter. I would start by adding about a half a can of Sea Foam to about a half tank of gas. Run it at idle until the new mixture is in the carbs 7 or 8 minutes ought to do it. Leave the bike sit overnight, then top off the gas tank and take the bike for a hard ride, ride it like you stole it, this should clear your problem. CV carbs also need to be synced once in awhile and should have been done if you rejetted.

The choke adds more fuel, so you might have a fuel issue. If it won't idle, but you can rev it up and it runs okay then, you need to have the pilot jets cleaned up. (I would go through the entire carb)

Backfire


is it a straight thru exhaust, or is it just a head pipe with nothing attached? If it's just a head pipe, you need to get some sort of muffler on it or you'll burn your valves out from a lean condition. The backfire is due to the vaccum fed carbs that yamaha runs. They work wonderfully, but under heavy deceleration, the vaccum still feeds the bowl, and it builds up excess fuel, which eventually burns off as a backfire. If it were fuel injected, you could have the fuel map adjusted to lean it out under deceleration.

Just broke its second pinion shaft i drive case at shoulder of thread first time it did it was under warranty


Sounds like tuning problems.
Yamaha cautioned on this.
First, make sure the engine remains in a good state of tune, valve clearance, carb sync, idle speed (STOCK, 1000~1100 rpms) idle mixture.
Then starting procedure, full choke no throttle when cold, do not try to rev it until the engine gets some heat in it.
