  • @jonrod48 - you need to pull the cover off and see why it isn't disengaging.

  • when you split the cases there is a seal on the front of the engine i need one, do you have them on your site and if you do can you give me the part # so i can buy it its for a 1999 yamaha yz 250

  • @Yamahayz2502t - sorry so late. Yes we have the O-ring that goes between the cases on that bike. part # 1241700001.

  • Also dont forget to purchase a Clymer or manufacturers manual.

  • After watching this video and purchasing all of the Tusk tools in it, I rebuilt the top and bottom end in a 1990 Suzuki RM250 with no issues. Since then I have rebuilt a 1988 Honda CR125 and a 2002 Yamaha YZ125, saving me lots of money instead of paying for labor at a shop or dealership. Thanks RockyMounainATVMC!

  • @RockyMountainATVMC its ok I will order it thanks for the reply

  • @breedam ohh you clever dog

  • Wow, you guys made that look super easy, but it doesn't look like it.
