20 Most Recent 2002 Yamaha V Star Classic - Page 3 Questions & Answers

start it up cold, and feel the exhaust pipes as it runs, and keep checking both near the engine. (Becareful as they should get hot quickly) A cold pipe means a dead cylinder. Then you need to verify three things...
does it have compression?
is it getting fuel?
does it have spark?

How good did you clean the carbs? The idle jets usually have small holes along the side, and if they are blocked with dirt or bad fuel, it won't idle. Make sure ALL of the passages are clear, and all jets are clear, through the center and holes in the sides of the pilot jets.

If you set your fuel petcock to "on" the bike will sputter when its low and you can switch over to reserve that has about another 1/2 gallon. I just set my trip meter and get gas about every 175 miles to be safe. 2007 VSTAR 1100 Classic.

Sounds like your carb jets may be partially plugged, common if they are stored incorrectly, The choke circuits on these carburetors work on manifold vacuum and if you throttle the bike while trying to start it you will lose the choke affect. if they are partially plugged the only good way to fix it is to pull the carburetors and clean them. I would advise checking out www.roadstarclinic.com is a great source of information for the yamaha star line of motorcycles.

Almost certainly a discharged battery ( have the battery fully charged ). - If that doesn't solve the problem then check the wiring connections to the starter motor, if they are loose or corroded they can overheat,also resulting in the symptoms you described. Tell me how you get on and Please leave feedback!!!!!

well, when i tried to post this question, "fixya" wanted me to give credit card information for a free trial. Screw that lol. and screw paying for information period. This is the internet. There is no silly question/answer i need to pay to post or get answered. So therefore i closed out this rediculous website and just went to yahoo answers and wiki. Question answered in minutes. Thanks

It is on the back side of the flywheel for the magneto/generator. You will need to remove the left engine side cover then pull the flywheel. It does take a special puller to get the fly wheel off. Once you get the flywheel off, there are 8 allen bolts that hold it to the back side of the flywheel.

oh yes..........
voltage regulator.... this unit also contains the rectifier which changes generator electricty from AC to DC for the battery. test the volt reg and it may be ok for the volts, but if the rectifier part is knackered, it will completely screw up every battery, they will not take AC !!!! every time I get a bike in for repair with volt reg. probs I always put in a new battery

under the left side of the gas tank you will see i black knob/screw at the end of what looks like a hose. the knob faces the rear of bike. that adjusts the idle. its real easy to find and the only adjustment you can make to the carbs.

Hi,
The first thing you need to check is the air filter. Sometimes critters can get into the airbox when a bike sits for awhile. Sounds crazy, but it has happened to me. If nothing is blocking the filter, give it a quick clean since you have it out.
Next things to check:
Faulty diaphragm
Improperly adjusted fuel level
Clogged or loose main jet
Faulty fuel pump
You may not be able to check these on your own, but these are the next likely culprits.
Hope this helped

If your 2005 model 650 motorcycle is experiencing a loss of power and struggles to go beyond 50 mph when you reach about 1/4 throttle, there could be several potential reasons for this issue. It's important to identify the underlying problem to resolve the performance concern. Here are some common causes to consider:

1. Fuel System Issues: Insufficient fuel supply or a clogged fuel filter can restrict the flow of fuel to the engine, leading to a loss of power. Check the fuel filter, fuel pump, and ensure the fuel lines are clear and not kinked.
2. Air Intake Blockage: A blocked air filter or a clogged air intake system can limit the amount of air entering the engine, affecting its performance. Clean or replace the air filter as necessary.
3. Carburetor Problems: If your motorcycle is equipped with a carburetor, issues such as a stuck float, clogged jets, or incorrect adjustments can lead to poor performance. Cleaning and tuning the carburetor might be necessary.
4. Ignition System Issues: Faulty spark plugs, ignition coils, or ignition timing problems can result in incomplete combustion, leading to a loss of power. Check and replace any faulty ignition components.
5. Exhaust System Blockage: A restricted exhaust system, such as a clogged or damaged muffler, can impede the flow of exhaust gases, affecting engine performance.
6. Engine Compression: Low engine compression due to worn piston rings or cylinder head gasket leaks can reduce engine power. A compression test can help diagnose this issue.
7. Throttle or Choke Cable Problems: A misadjusted or sticking throttle or choke cable can affect the fuel-air mixture and throttle response. Ensure that the cables are properly adjusted and move freely.
8. Electrical Issues: Faulty sensors, wiring problems, or issues with the electronic control unit (ECU) can impact engine performance. A diagnostic scan might be required to identify electrical problems accurately.
9. Valve Clearance: Incorrect valve clearance can affect engine performance. Ensure the valve clearance is within the manufacturer's specifications.
10. Transmission or Clutch Problems: Issues with the transmission or clutch can result in power loss and limited top speed. Inspect and service the transmission and clutch components.

It's essential to perform a systematic inspection and troubleshooting process to pinpoint the exact cause of the problem. If you are unsure about diagnosing or fixing the issue yourself, it's recommended to seek the assistance of a qualified motorcycle mechanic or dealership. They have the expertise and tools to diagnose and repair the problem effectively.

Buy a fuel injected bike !! LoL !!!

You have dirty clogged jets in your carbs. Remove the carbs and clean and clear the pilot jets and main jets.

Stuff like that is non critical, tighten loose, then snug it it up a bit.
