Hey guys Ive had my wr426 for a couple of weeks now and I just gave it an oil change, cleaned the air filter and filled it up with premium unleaded (ive been running on ordinary unleaded). After I changed the oil I took it for a ride and all was good. The next morning I cleaned the filter and filled it with fuel and it refuses to start. Initially I though there must be too too much liquid in the filter element so I checked that but it still doesn't even look like starting. Any advice?

Also I tried checking the spark plug but an hour later once I had the bike apart I realised there must be a special tool to get the bloody thing out since Yamaha did their best to hide it. Better go see the dealer tomorrow and get one...

Not a bunch of info to go on but one possibility (and this is abstract) is that maybe the carb slipped off of the boot that links it to the head if the plug doesn't get youback up. Im no expert but I would always run premium if I were you given the high compression. Factory recommends 95 octane on my 05 I think, so premium is close cuttins.

pull out the spark plug and check for spark , you need a 5/8" spark plug socket .

yeah turned out it was just a dead spark plug. Only problem was it took me a day to design a tool to get it out since I dont have the one u get from the dealer when you buy the bike. Then it took a day to order in a new plug but now once I got it in it fired first kick. I find it runs alot better on premium unleaded too so Im going to pay the extra 5 bucks from now on

ya never run it on anything less then premium . to take out the spark plug all you need is a spark plug socket and a extension , a universal joint makes it easier and a ratchet .

didn't know there was a special tool .

thats good you got it figured out .

Yes, the sparkplug wrench and universal will get you right to the top of the head cover, then a short or long extension and it's out.
I ended up picking up the tool from Yamaha, it's in my trail kit because it's small and light, it protrudes just past the top of the head and all you need is an adjustable or 12mm? to turn it.
Also, the top portion of the tool will work to remove your seat.
