Question about 2002 Yamaha TT-R 225

1 Answer

My 2002 yamaha ttr 225 is running really lean and is really hard to start, and even whenever it does start i have to leave my choke wide open for it to stay running. It runs so lean that my exhaust pipe turns bright red. I cannot figure out what the problem could be.

Well it is normal for a four strokes exhuast to turn red your not suppose to let them idle for long periods of time. and the running problem is probably the carb i would take it off and clean it before doing anything else could save you money i had the same problem on a yz450f i took the carb off and cleaned it and problem was solved and also run 93 octane gas if your not already

2004 yamaha ttr225 smoke's really bad out the exhaust and oil goes threw dont know where but come's out the exhaust,have changed the valve seals and all ring's and head gasket but still same problem,what...


Hi, Pauljackson your instrument gauges and lights can alert you to most electrical and engine issues they can not warn you about failed engine gaskets or seals so your engine has to resort to old fashion alert methods of colored "SMOKE SIGNALS" here is a breakdown of their meaning:
1. COLORLESS OR SLIGHTLY BLUE SMOKE on start-up means your air/fuel mixture is at the right composition and everything is well burnt in your combustion chamber.
2. BLUE SMOKE on start-up is usually caused by failed valve seals dripping oil into the combustion chamber when the engine is not running.
3. YELLOW OR BROWNISH SMOKE at start-up means your air/fuel mixture is too lean. Too lean means that there is low fuel but high air mixture in your combustion chamber.
4. WHITE SMOKE on start-up may be caused by a blown head gasket allowing coolant to enter the combustion chamber and may start dripping out of the exhaust pipes or mufflers. Smoke while riding is usually caused by worn out or damaged valves, seals, guides, pistons, rings, or cylinder walls.
5. BLACK SMOKE on start-up is usually caused by too much fuel in the combustion chamber this can be due to air/fuel mixture adjustment too rich, accelerator pump improperly adjusted, faulty choke/enrichner or not in the off position, air filter dirty and clogged, faulty carburetor float needle and seat, pilot jet too large, fuel injectors leaking, smoke while riding is usually caused by the main jet being too large or a damaged carburetor.
It should be noted that aggressive or abnormal throttle operation will cause these conditions to manifest themselves exponentially.

Yamaha ttr 90 jet pilot should it be open end to


The pilot should be open. This is to say that if you look through it at a light you should be able to see through it.
I suggest blowing it out with compressed air as well as the hole it fits in. While your at it give all the jets a blow out.
once you've put it back together I also suggest you fit an in-line fuel filter.
This will help to keep the dirt out and save you having ths same problem again
Hope this helps

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.
