i know this is a stupid question but whats up with the spark plug on the 400. why the **** is it so hard to get to? what is the secret to taking it out? do i have to take the front plastics and gas tank off?

Posted by: 400exredrider

no take ur wrench outta the tool box the spark plug one....take the wire off put the spark plug wrench in there get a screw driver and turn it LEFT and it will come out

take off the front plastics, take off the gas tank, take the engine out of the frame, take the little red thing off, and take the spark plug out

He is right.

If you lose or just don't have the special wrench to get the plug out. Than its a huge pain.

yeah, the first time i did it on my freinds, i took the gas tank and verything off. then my dad laughed at me and used a wrench out of his big bear tool kit and could get to it with ease

i usually have a bunch of crap stuck around the plug(grass,mud and such), so i take most stuff off so i can keep it cleaner when i change my plug.

at least its not a 2 stroke so you dont have to change it every ride

The word is Motion Pro. They make a socket just for it you can use a 3/8 ratchet or a open end wench or scew driver to get your
spark plug out works great for me and it's under 30 dollars. To find them at [650]594-9600 or www.motionpro.com:)

I blow out with compressed air down around the spark plug before i pull it.

If you got to pull the plug on your two stroke that much, you got something wrong somewhere. I pull the plugs about every 3 months on the dirt bikes, they always look good and start right up. I change the plugs when they get some wear, about every 9-12 months or so.

i used to have to change my spark plug every time i unloaded my 400 at the deer lease. its only about 2 hours north of here , and i dont think elevation could have affected it that much. also , i used to go thru plugs about once a week. but now that i have rejetted it for my pipe , it fires up everytime. so i have like 5 spare plugs still in the box in my shop lol.

MX MadMann, My 400 is like yours. Ever since I put my Pipe on it is a Pain. I have the Jetting right because I asked TC and he told me to run a D7EA Plug which helped, but it still fouled out. It was like 70 and a cold wind today and it would barely start. It is starting to be more of a Pain then anything. It seems like I change Plugs every 2 weeks or sooner. I hope when it hets Hotter it helps that some. I am so good at changing the Plug now I could do it in like 2 minutes.
