They're not tappets--you can adjust them with a wrench and a set of feeler gauges. Here are the clearance measurment numbers for intake and exhaust:

  • 0.08mm - 0.13mm for the intake valve clearance
  • 0.11mm - 0.16mm for the exhaust valve clearance

There is much more helpful information on this web page:

You will also find lots of valuable information on your GPX 250 (called a "Ninja 250" or "EX 250" in America) on this web site:

Good luck!

What are the tappit settings for a mitsubish montero io GDI 2001 petrol


hi its ok ive found it no need for engine size i gather its a 3.5ltr, these should have hydraulic tappit's and therefore do not need adjusting, as you cannot adjust them, if however they are rattling you may either have blocked oil ducts in the engine, which will need to be flushed, or they are worn to the extent that they will need replacing, or check your oil level it might be to low and needs topping up, or even still the oil has got to thin and will need changing....hope this helps please vote thanks

Pull triger the welder wouln't start and the wire dozn't feed


You could have a couple of things wrong. A bad trigger switch is very common. That is about 99% of the time. Next are connections to the box.Not too common but they can corrode or get loose. Then you can have drive motor issues or something annoying like a pinched or galled liner stopping the wire.

To rule out most things we need to know if the wire feeder is working or trying to. All we need to do is press the trigger and listen for the feeder motor. We want to do this with the top open so we can see it as well. If it doesn't do anything then we need to look at the switch, connections or the motor itself.

If it sounds/looks like it wants to work then we might have something simple like the wire drive or pickup being out of adjustment or worn or the wrong size or type for the wire you are using. If you lay the lines out straight and then try to manually move the wire it should be stiff but smooth. Use pliers at the pistol to pull on the wire, and loosen off the driver wheel tension. If the liner has a kink or was damaged then the wire will not feed or will be very hard to move.

My bet would be on the switch.

Could be carb adjustment, cracked fuel lines,bad ignition module, carb needs adjusting, bad fuel filter,or a scored piston and cylinder. Dont know what type saw you run but if compression is under 80 on a poulan it needs a new piston,rings and cylinder head. Need more info.
