How in the world do you get to the spark plug on a wr400f? Do you have to remove the gas tank? :thumbsup:

Yes. On my 04 450 I need to remove the seat so that I can remove the tank. Even then the frame makes it a tight fit for your tools to get dwn in there to the plug... my 04 came with a tool that is designed for pulling the plug.

Marcus, have you bought a powerband for your bike yet? You need one. They are great. I think one of the guys on the board was tryiong to sell one. I think he had a red one.

MArcus, you will find it easier to rmove the tank, fit the plug spanner in a bench vice, the lift the bike up, positioning the plug hex in the spanner. Then, by merely rotating the motorcycle approximately 15 complete turns, you will see the plug has been removed.

Simple when you know how.

Glad to be of help.

what! what! Powerbands suck! Once you get off the Powerband for 1 second it's hard to get back on the powerband! Powerbands are for 2-strokes only! I have power everywhere! Low, mid, and high rpm! :thumbsup:

Tilt the bars forward and remove both tires, the plug will come right out. Works for me! :thumbsup:

No, you don't have to remove the gas tank. The way we do it is to remove the seat and unbolt the gas tank and raise it up aprox. 8". But don't remove it.
Then, unbolt the sub-frame and swing it up out of the way. Remove the carburator, cables and fuel lines and hoses. Unhook the oil lines and drain the oil. Unbolt the top engine mount,( this is why you have to raise the tank 8") and then unbolt the front and lower engine mounts. Loosen the swingarm bolt and slide it out. Unhook all wire connections and remove the engine from the right side of the frame.

With the engine sitting on the floor you will find that the spark plug is now easy to access.

The clamping of the plug wrench in a vice and spinning the motorcycle doesn't work unless you have the special Work's Contraption spark plug wrench with the extended handle. Otherwise the wheels of your motorcycle will hit the bench when you try to unscrew the motorcycle from the spark plug.

Jeeze you guys. :thinking:This ain't rocket surgery ya know. :devil:

I USALLY DROP THE MOTOR WHEN I HAVE TO CHANGE THE PLUG.

STEP 1: REMOVE FRONT & REAR TIRE
STEP 2: REMOVE TANK AND SHROUDS
STEP 3: REMOVE MOTOR FROM FRAME
STEP 4: PULL HEAD OF ENGINE
STEP 5: CHANGE PLUG

ALWAYS HOLD THE BLACK WIRE IN YOUR HAND TO CHECK FOR SPARK!!

dirtryder52 is right apart from one thing. Before fitting the plug, you must check it sparks or all that reassembly is wasted.
Best to fit the plug to the cap, then place the spark end of the plug on your tongue. Turn the motor over on the kick start. You should know if the plug works!! :thumbsup:

Useful insight on a thread called "Spark Plug"??? :worthy:

This forum used to be loaded with skilled, knowledgeable riders that we all could learn from. But instead, they now go elsewhere and we get stuck with trash like "What color bars should I use" and "Does JD make a jet kit for my toilet?"

When you see everyone rip on a poster, you should do a search and look at the subjects and postings. This zero named “marcusmoberg” has been asking dumb ass questions for a few years and it truly has polluted the gene pool. This garbage brings no value to a forum that contains racers and serious riders.

If you are a novice/newbie, that is cool. Sit back, search the 1233 pages of information – learn and research the valuable data that was generated over the years. The folks that used to summit data were very sharp..Where is Taffy or LarryCO? I would guess that they have gone to another forum that doesn’t waste their time.

Be respectful to all of your fellow users by researching your questions first and allow the people that really do know more than us to give their input. If all the smart guys go away, then it is just losers talking about why the rear tire on their WR is black and has knobs on it.

Respectfully yours,

Chad
