2006 Yamaha TTR 125E - carb not getting gas


Hi, Kevin always check fuel flow first to isolate the problem area otherwise the usual suspects are:
1. Fuel tank empty.
2. Fuel cap or fuel tank not venting properly.
3. Fuel filter clogged with rust or dirt.
4. Fuel valve/petcock not in the on or reserve position.
5. Vacuum line to fuel valve cracked, broken, pinched, or missing*
6. Fuel valve/petcock clogged or diaphragm cracked, cut or torn*
7. Fuel line from the fuel valve to the carburetor or fuel pump clogged, cracked, pinched, bent, broken, or missing.
8. Fuel pump not working*
9. Fuel line touching cylinder or head causing fuel to boil and vapor lock, repair by rerouting and wrapping line with convoluted tubing.
10. Carburetor inlet clogged.
11. Carburetor float or needle and seat stuck.
12. Carburetor not venting properly overflow line or bowl fitting clogged, pinched, or bent.

Hi Anonymous, if you have a carburator the usual suspects are:
1. Damaged or restricted fuel tank venting system (gas cap).
2. Inlet system air leak.

4. Accelerator pump leaking or no output.
5. Plugged bowl vent.
6. Fuel level (float chamber) too low.
7. Restriccted fuel supply passages.
8. Plugged jets or passages.
9. Worn or damaged needle or needle jet.
10. Enrichner valve not seated or leaking.
Good luck

2006 vmax less than 3k miles. didn't ride it one year and only started it up a few times. Heard fuel may tarnish if sitting. starts right up with the choke on, but wouldn't idle with choke off. ...


You did our ride a disservice letting gas sit in the carb for over one year. My guess is your carb is all gummed up with old gas (called varnish in some circles). You may be able to get it clean using carb cleaner available from the auto parts place. Don't spill any on the paint - it will eat your paint!!! Still, give it a try. If that doesn't work, you may have to remove the carbs and rebuild or replace with new rebuilt.

Of course, you could take your ride to the Yamaha shop and have this problem solved in short order by the professional who are familiar with this problem and the remede.

In the future, after you get this fixed, if you intend to not ride for an extended period of time, do the following? Fill the fuel tank. Add a fuel stabilizer recommended by the manufacturer. Go for a ride. When you are about 1/10 mile from home, turn the fuel supply valve OFF. When you arrive home, allow the bike to run till it stops. Park your ride in a dark, dry place. Disconnect the battery and after it is cool, clean everything and apply wax to the finish and cover it up. When you want to ride next time, you will find it will be ready to go after you connect the battery and turn on the fuel. If it is a year, you may want to put a little charge in the battery, or if it is more than 3 years old, just replace it.

I hope you find these remarks helpful. Thank you for your interest in FixYa.com

Bike will idle but when you give it throdel it dies


It could just be that the carb is gummed up. The first thing usually worth trying is running some SeaFoam or a similar carb cleaner through the engine.
1) You want to find a liquid carb cleaner (one that is added to your gas tank) 2) Empty your gas tank (either by running the bike or draining the tank) 3) Put some SeaFoam in the tank 4) Fill the tank up and run the bike
The container will probably tell you how much SeaFoam to add for a car. Take a third of that number to figure out how much to put in your bike.
I've found this solution to work as a great first attempt for a variety of engine problems on my Honda motorbike. Hope it helps.

Hi 2000 yamaha Vmax, 4600 miles on the clock.


This sounds like a carburetor problem. Either bad gas, partially plugged pilot jets, carb diaphragm cracked or has a pin hole, carbs out of sync or diaphragm cap is not tight. It would be best to have a dealer check it out. However, before going to the dealer I would try one thing. Drain the float bowls on all four carbs. There is a drain plug on the bottom of each bowl. Condensation inside the gas tank can make it's way into the carb. Bikes don't run well with water in the gas. Please rate my solution. Thanks.

My 05 shadow sabre starts, runs & idles fine except at high rpm (half to full throttle) air filter & plugs look ok. Has dg pipes and supposedly was rejetted. Just bought the bike & do not know...


i think you are on the right track, i would try draining and refilling tank with fresh gas,if it doesn't help, then likely the main jet has become partially clogged from improper storage or may just be, have you tried running on partial choke to see if it helps, this will comfirm a high speed lean mixture, you could try running a good fuel system cleaner b4 tearing carb apart, i like using a product called seafoam, cleans carb and carbon from engines. 1oz. pergallon. just be happy you only have one carb to mess with my vmax has four, yikes!!!!!!!!!good luc, feel free to e-mail me

Buell blast is backfiring. Sat for 2 years so, cleaned fuel tank and cleaned carb. It will start now but is backfiring and will die of I try to idle. Thanks


If you did not completely disassemble the carb and remove all jets/emulsion tubes/needle valves then you did not clean the carb adequately. You could try adding either Seafoam, the Yamaha CARB-CL-EAN-ER, or Techron fuel system cleaner in an auxiliary gas tank and running the engine for a short while to ensure the mix gets into all the nooks and crannies. Let it sit for a couple hours to do the work, then drain out the float bowl, hook up the bike's gas tank and see what happens. Otherwise you need to remove, strip, clean, reassemble, and reinstall the carb.

Vmax engine will not idle without the choke on.


Sounds like your carb. may be gummed up. Did you start the bike and let the carb. get stabilized fuel into it when you parked it?
