Question about 2005 Yamaha PW 50

1 Answer

Pw50 leaks gas

I could not get the bike to stay running, so I cleaned the carb. Bike fired up and ran great, but then noticed that gas was pouring out the over flow. I have pulled the carb apart again and have come to the conclusion that the needle valve is not seating. Could this be the problem?

Hi, Anonymous "ABSOLUTELY" and the usual suspects are:
1. Damaged or restricted fuel tank venting system.
2. Loose float bowl screws.
3. Damaged float bowl o-ring.
4. improper fuel level in the float bowl.
5. Worn or dirty inlet valve or seat.
6. Damaged or leaking float assembly.
7. Particle contamination in inlet fitting cavity.

I have had several bikes in my time. and keeping the carbs syncranized is very important. Did you put aftermarket pipes on it? try rejeting the carbs up 2+mm that may help the fuel air ratio?

SOURCE: Rear Carb leaks fuel out of overflow

Hole in the float. It fills with gas, sinks and fails to stop the fuel flow

Theres fuel starvation, the carbs are not getting required fuel in other words the float chambers doesnt get the correct amount of fuel .
Check the fuel flow from the petcock to the carburators.
Check the float pin and adjust accordingly to get the right level inthe float chamber of each carburator.
Hope this helps!

What should I check next? Not getting any error codes, replaced the CKP, MAP, IAC, TP, & ET Sensors. Not sure what I should try next, any suggestions would be appreciated.


Hi Bruce, might have gotten some bad gas. Drain the tank, clean the fuel filter, check the bottom of tank for rust, dirt, water ect. Then ckeck fuel pump pressure, refill tank with a gallon of fresh gas from a different source and take it for a ride. good luck

What is causing steam from my exhaust pipe and bike won't stay running?


It's probably dirt in the carbs and the steam is the un burnt fuel from a stuck needle valve in the carb

My bike backfires bad but it idles perfect and the pipe gets real hot fast


Could be you have air leaks in the intake manifold connections causing a lean burn situation, which can cause loud noises from the exhaust, fireing back through the carb/injectors, and the pipe and engine to get extremely ho
with engine running, spray carb cleaner over and around the intake connections. If you hear the engine change tone or smooth out in it's running, you have found the leak. Fix the leak and the other problems could go away. If the bike has been setting for a length of time, your jets and passages could be gummed and needing a cleaning. If there is a possibility of gummed jets, pour 1/4 to 1/2 can of SeaFoam into the gas tank, lock down the front brake and rock the bike back and forth to mix the gas and SeaFoam. Start the bike and run at a high idle for a few minutes. Shut it down and let it cool, then do it again. If it is gummed or dirty jets, they should start to clean up shortly.

MY HONDA A.C.E WONT STAY RUNNING WITHOUT THE CHOKE PULLED, BUT RUNS GREAT WITH CHOKE PULLED. I'VE RAN GUMOUT THROUGH GAS, SLIGHT NOTICEABLE CHANGE BUT NOTHING DRASTIC


You need to take the carburetors off the machine and open them up. Pull the jets out, make sure they are clear and you can see through them. Squirt carburetor cleaner through the passageways in the carburetor body and blow the passageways out. That is where the carburetor dirt is hiding. Use genuine Honda carburetor cleaner . Gumout is too harsh for Keihin carbs. If you want to try to clean the carburetors without disassembly buy some Chevron Techron and pour it directly into the bowls. Let it sit over night. Drain your gas tank and follow the directions on the bottle to mix 1 gallon of gasoline in a shock treatment. Pour the shock treatment in the tank , start the bike, slowly take the choke off, and run it till it idles on it's own (usually 5-10 minutes). Be careful not to let the pipes get too hot or they may blue. Then take it for a 5-10 mile drive and fill the gas tank. If the carburetors are not too bad this should clean them up. Other wise you will have to take them apart to clean them properly.

DRAIN CARBS FROM PETCOCK AT BOTTOM OF EACH CARB MAKE SURE FUEL DRAINS COMPLETELY THEN TURN FUEL BACK ON, IF THIS IS AN INJECTED MODEL DRAIN TANK AND FLUSH THEN RUN IT HARD FOR 20 MILES OR SO, MAKE SURE YOUR OIL LEVEL IS OK

Yamaha V-Star 1100 backfires and will not run without choke on


Here are two solutions for you:
A - Take the carberator off and soak it in some good quality carb cleaner for about 1/2 an hour.  That should take care of any residue in the carbs.
B - Alternatively (and for the less technical minded) there is a great product called Sea Foam.  Try to find it at your local CSK auto/NAPA/Wal-Mart.  Pour a small amount (maybe 1/4 ounce) into each cylinder chamber (take out the spark plugs), try to pour a small amount into the carbs (a turkey baster works great for this), and pour the rest into the gas tank.  Let it sit for 5-10 minutes, then start it up.  *NOTE - the bike will start VERY hard at first until it burns through what's in the cylinders.  ALSO the fumes will be EXTREMELY strong and suffocating - make sure you do this OUTDOORS preferably, or at least in a VERY well ventilated area.
Good luck - I know how frustrating these things can be! :)
P.S. - I am a proud owner of a V-Star 1300 - great bikes! :)
