Any tips on changing a spark plug on a Yahama WR250, its buried right down in the engine head?

Will I have to take off the tank ?





Can I take off the tank without having to drain it ?





I think I might need a special socket to reach down into the engine head ?|||tank stays on,you can get it from the r/h side....


i use a 3/8th drive plug socket and a 3/8th drive %26#039;%26#039;wobbly joint%26#039;%26#039; and ratchet....|||special socket called a spark plug socket and sure you can take tank off just shut off fuel line wil shut off fuel|||Yes, A spark plug socket, you should not have to pull the tank. If you do just shut the fuel valve off on the line coming out of the tank. Is this just a maintenance change or did it foul? Either way if you replace it make sure it is a NGK brand spark plug. to prevent problems down the road later.Champion plugs will foul out easier.|||you do need a special socket but any motor factors should have it as for the tank its not too much hassle to remove it and you will need to. (you dont have to drain it as there is a plastic tube for the fuel line.) in new models|||Removing spark plugs normally require a special socket. Removing the tank is simple enough. with the cut off switch on, clamp the fuel line. remove the tank. OR sythen the fuel (presuming you know how, pipe in the tank, with it lower the the tank (on the outside) suck, till it runs).





Be careful when replacing spark plugs, make sure to get no oil or grease on them.





hope this helped.|||I have an adjustable extension that makes it real easy from me to change my plugs.|||not sure you have to take off the tank

if you prefer taking off the tank
