Cant find my oil filter on my 2001yzf 426
Right hand side right next to the water pump in between the big clutch cover and the water pump cover you will see a small cap about 6- 8cm has 3 bolts they will be 8ml bolts or maybe allen bolts on the older YZ
Tip drain all your sump oil first before opening and lean bike over to the left as much as you can to save big mess of oil coming out when you open this cover. Don't forget to smear some clean oil on the rubber on the end of new filter before installing it will help seal it and keeps in place a bit so you can install cap back on easier...
My 2003 yz426 is overheating.
Things to check 1st. If it overheats after riding for a while, check the air filter. If the filter is not sealed properly, air will get in between the seal and the airbox causing the bike to overheat. Other possibilities on a bike that old would be clogged radiator tubes(replace), bad water pump(replace impeller)
