First I would pull the spark plug to see what it looked like, you want it to be a chocolate color. If it is black and wet then yes you are running rich. Also check your air filter, go ahead and clean the filter. If all this doesnt solve the problem then we probably need to look at our carb.

This isnt a fun fix i know i have a 04 ttr 225 and your probably going to have to take the carb off and adjust the fuel screw which is almost impossible to get to while its on the bike and if you dont know how to do it find someone who knows what they are doing and you should be riding soon enough it only takes about an hour or 2

What causes a lot of backfire?


Backfiring with flames usually means 2 things1) Rich mixture (lots of fuel). The spark plugs becomes black powdered. Need good carburetor setup (main jet, needle, pilot screw adjustments)2) Poor valve sealing. Damaged valve seats causes that. Need to take apart the cylinder head and grind the valves (procedure that all mechanics know). That means that when the mixture is compressed inside the chamber and ignited part of the mixture explosion escapes from the leaking valve's seat to the exhaust, so concentrated unburnt fuel in the exhaust catches fire and explodes through the exhaust, creating the flame.

2002 yamaha ttr 225 idles high when let off gas but eventually idles down on its own and hard to start when cold with choke or without


Hi, David and the usual suspects are:
1. Throttle cables improperly adjusted, pinched or need lubrication.
2. Idle adjusting screw needs to be backed off.
4. Air fuel mixture adjusted too lean start with 2 full turns.
5. Intake system air leak.
6. Fast idle choke ramp is not releasing.
7. Broken throttle return spring.
8. Damaged diaphragm or slide.
9. Faulty MAP, TPS, ATS, O2, sensors or wiring/connector
10. Multi carburetors not in sync.

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.

New exhaust on my wr 450f and its gargling and back firing


You have probably restricted the exhaust too much. Causing it to run rich. you will have to adjust your air mixture screw and lean it out. But first, check the color of your spark plug. Lean it out if it's dark, richen it if it's white. Your looking for a nice carrot color. The plug never lies. :)

Replaced stater,put bike back togeather, and now have flames


If you're seeing fire coming out of your pipes, you need to adjust your timing and lean out your carb. It's running too rich.
