Spark Plug Access

8 posts in this topic

I just sold my XR650R and bought the WR 400. Great bike. I have a simple question, How do you access the spark plug?? Do I need to remove the seat/tank to change the plug or there is an easier way?

I own a 2001 WR426 and I have to remove both my seat and tank to access my plug. Hope this helps.

Good luck!

If you have the factory plug wrench you do not have to remove anything but the plug wire. I have a 98 WR400 and it works fine without removing anything else.

Hoss most important, take the tank and seat off and LOOK inside the spark plug hole and check for dirt before you take the plug out. If there is any dirt, blow it out with compressed air first. Otherwise it'll fall inside your cylinder, in which case you might as well run it without an air cleaner.

I never tried to use that crappy plug wrench or tried to remove the plug without removing seat and tank. I own a 01 WR426. It really doesn't take that long to remove that stuff. Besides you may want to use some air before removing the plug to get the water and crap out of there. My 2 cents

It only takes about 6 minutes to remove the two seat bolts the rubber tension strap, fuel line and the two inner tank mount bolts, change the plug and reassemble ready to ride. Or as has been suggested you could use the knuckle buster Yamaha Plug wrench and take the chance of droping debris in the cylinder hole and go for the 6 hour upper end rebuild......

I like the 6 minute way myself, it also gives me time to look for wire chaffing and other things that you don't see on a daily basis.
