Question about 2004 Yamaha TT-R 225

1 Answer

When I start my 2004 Yamaha TTR 225 on full choke and pull back on the throttle the bike starts to die. If I let off the throttle it will sound normal again. I have cleaned the air filter and I have cleaned the bottom of the fuel tank. I have no idea what is wrong with it.

Remove the fuel tank , side covers , and seat. Take your carburetor off , clean and inspect it. Check the carburetor top diaphragm. Make sure all the jets are in place and the passageways through the body are clear as well as the jets are clear. Squirt carburetor cleaning fluid through them. Most of all inspect the intake boot for rips tears and separation. Make sure your mixture screw is set to 2 full turns. Reassemble and your problem should be solved.

04 ttr 225 carb appears to be gummed up. Full throttle is OK but need choke on full to idle and run at slow speeds


Hi, Shall582 and the usual suspects are:
1. Fuel cap or fuel tank is not venting properly.
2. Fuel filter clogged.
3. Fuel line pinched or kinked.

5. Float needle and seat sticking.
6. Float level too low.

I have a 2003 ttr225 I can get the bike to start with the choke on ihave to let it warm up for an extremly long time before I can push in the choke . once the bike is warm and I hit the throttle hard ,...


Sounds like the idle circuit in the carb is restricted. The engine is running on the choke only. When the engine reaches a certain temp the fuelthat does get is more readily burned allowing you to back off the choke. The choke probsbly can't be completely opened? right? Fuel quality is also something to consider Oil content in fuel affects combustion temps and volatility. _good luck_Ned_

Carba/f ratio needs adjusting and use of the choke will help keep the idle circuits clean.

Yamaha 2002 TTr 250


Hi hoeygatt

Look around your bike near where the throttle cable meets the engine, when you pull the throttle, the cable pulls a quarter circle piece of metal which is connected to a spring, then connected to that should be a screw, that is the idle screw, turn it very slightly, usually clockwise to make the idle higher, and this should sort out the problem.

Please remember to rate this solution as FixYa!

Hard starting of a yamaha ttr 225 after sitting for several weeks. Could starter plunger in the carb be bad?


I had a similar problem with my TTR 125. I removed the carb, removed the float bowl and gave a a careful clean. I also removed the choke plunger mechanism and gave that a few shots of penetrating lube oil. The choke mechanism works much smoother as a result.
Just those two simple things and my bike fired up right away.
