1. Engine oil level and SAE weight are too low or not circulating.

3. Heavy combustion chamber carbon deposits.
4. Ignition timing retarded due to faulty MAP, CKP, or CMP sensor.

I have a 2002 Yamaha YZ 426f that is incredibly hard to start.

Hi, Jacob and the usual suspects are:
1. Spark plugs in bad condition or have an improper gap or are partially fouled.
2. Spark plug cables in bad condition.
3. Battery damaged or nearly discharged, should have 12.5 volts.
4. Check battery terminals for damage or corrosion, check the battery cables at "BOTH" ends for loose, corroded, or broken connectors, "INSIDE" and outside the cable harness, perform connector wiggle test and check cables with an ohmmeter if necessary.
5. Throttle controls not adjusted correctly.
6. Water or dirt in the fuel system.
7. Water or dirt in the carburetor.
8. Intake air leak.
9. Fuel tank vent hose and vapor valve plugged, or fuel line closed off, restricting fuel flow.
10. Enricher valve inoperative.
11. Engine lubricant to heavy (winter operation).
12. Ignition is not functioning properly (possible sensor failure).
13. Faulty ignition coil.
14. Valves sticking.

Hi need help I've got a 2002 wr 426f but need new frame I can buy a yzf 250 2002 frame but not sure if it will fit I know ill lose my kick stand

Yes the YZ frame will work perfect.
The main difference in a WR to a YZ is the extra weight that the flywheel has on the WR's engine,other than that the bikes are about identical.
Good luck,Gary

That is what an oil filter is for. Some people fit magnetic sump plugs to catch the bits of metal that drop into the bottom of the sump.
Don't worry, it's normal.

Need some info on changing my water pump on a 2000 Suzuki GSX-R600

Remove the lower fairing.
Remaove radiator cap, disconnect water hose from the water pump and drain coolant.
Remove the oil drain plug to drain engine oil, remove the coolant reservoir tank.
Remove gearshift lever and engine sprocket cover.
Disconnect water hoses.
Remove the water pump mounting bolt and the water pump assembly.

Replacement is the reverse and don't forget to refill the oil!

Bring it back .. work should be under warranty of some sort. Also if the engine is running but stalling due to fouled plug then maybe the oil injector is not adjusted properly or the oil/fuel mix is not right for some reason.

My Yz 426F and it won`t start at all, changed the plug and it still won`t start

HELLO; Now, pull the plug out reinstall it on the ing. cable and short it out on the head while cranking the motor over ,look for a nice crisp spark. If you have one, check for fuel flow from your tank to the carb. Check that and if nothing, write back and we will go from there. GOOD LUCK.
