The excess fuel is caused by the float levels being out of adjustment. Fix the floats and the dead spot may disappear. If not, pull the slides and then move the jet needle clip down one notch. With due respect, I would put the bike carbs back to stock. :)

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.
