      The Hop-Up: You may be saying to yourself, “that’s a chick bike,” and you’re right. But honestly, it’s so much more than that. It’s one badass bike. http://www.quadmagazine.com/quad/features/article/0,24942,1587044,00.html

      I just got a 1991 Yamaha Moto 4 for my son and I am looking for a service repair manual. I know that the timing chain needs replaced.

      When I push down on the rear brake pedal, it makes the left hand brake very sloppy. Is there a way to adjust that? I have a 2007 Suzuki Vinson

      Hi all, my second post here
      I got an old Yamaha 88 moto 4 and I have a problem with my overflow hose from the carb.
      When I put the gas switch to ON a big amount of gas is leaking from the overflow...so I start using my quad with the gas switch to RESERVE wich is also leaking but less than in ON position.
      I dont ride a lot..but in a week I empty my gas tank.
      Strange.
      I never clean my carb because Im new to quad world and dont have the service manual...so I need you point of view.
      Thanks guys!

      Hi all, I try to find this manual in the threads but you have a lot of stock here
      Cannot find this particular manual.
      I found it for YFM200 but not sure if they are the same.
      Thanks if you could help me with that.
      Im new here so if I did something wrong, please tell me.
