400ex smokes out of Breather on valve cover

If you put new rigs in and if you broke one you may be getting blow by causing too much crank case pressure. Most valve covers with a tune in it should have a hose on it and probably feeds back to the breather box. Check out parts schematics on line and see if there is a hose. If it does then you'll need it.

Well, i found the breather tube that i tucked away up in the front of the plastic when i did the top end, i guess i just forgot about it,  Hooked it up and ran great with no smoke. Oil level was perfect and oil was nice and clean.  Also after the break in process had to adjust the valves again. They were loud as hell after about an hour of run time. Seems like everything is working as it should now..... Thanks everyone for the tips

      having an issue with the unit when running under a load up a hill or in high gear, seems like the belt is slipping, there is a clapping sound coming from the primary clutch like it releases and snaps back in. i don't think I should have a noise like that. this is a friends unit and he has already replaced the primary twice with the same result.
      not sure where to look next

      Bucking started about a month ago and works ok after 1/2 hour warmup.  Today while working on it i discovered that if i put the ignition switch in LIGHT position it runs fine right from the start.
      I'm stumped!  Any idea why this could be?

      For those of you who are into coffee, I found this little article that might interest some of you.

      I admit it. I am a coffee snob. I try not to be obnoxious about it, but let the record show: I enjoy a really great cup of coffee. But pay $4 a cup for it? No way. Even snobs have their limits.
      Over the years, I’ve learned that a really good cup of coffee has less to do with money and more to do with knowledge and care. In fact—and this is the amazing thing—the more I learn, the less I spend.
      BEANS. Purchase whole bean coffee as soon after it has been roasted as possible. Freshness is the key to a superb cup of coffee. Purchase in small amounts—only as much as you can use within 2 weeks of being roasted.
      RATIO. The perfect ratio of coffee beans (prior to grinding) and water is: One-half cup whole beans to 8 cups of water.
      GRIND. Grind your beans as close to brew time as possible. A burr or mill grinder that crushes the beans is preferable to a blade grinder that cuts them. Once ground, coffee should be used immediately.
      WATER. If your water is highly chlorinated use bottled or filtered water. It must be right at 200 F, just short of boiling temperature, when it hits the dry grinds. This is critical to creating a great cup of coffee. Consume immediately.
      STORE. The enemies of roasted coffee beans are air, moisture, heat and light—in that order. Keep your beans in an airtight container that is not close to moisture (sink, dishwasher), heat (oven, stove) or light (countertop). Do not store your daily coffee in the refrigerator or freezer because contact with moisture causes it to deteriorate. For larger quantities of roasted beans that you cannot use within 2 weeks, wrap in airtight bags and store for up to a month in the freezer—making sure the beans are completely protected against moisture. Once removed from the freezer, do not return.
      BUY. Most supermarkets offer high-quality, roasted coffee beans for $.60 to $1 per ounce ($9.50 - $16.00 per pound). Ouch! Discount warehouse clubs like Costco, Sam’s and B.J.’s have considerably less expensive coffee at about $9 a pound for name brands like Starbuck’s and Peet’s. Still, that’s too rich for my blood.
      ROAST. I roast my own coffee for two reasons: It is infinitely better tasting and half the price. I purchase green coffee beans by mail order for about $4 - $6 a pound, depending on current conditions and variety. I started out roasting in a popcorn popper (West Bend’s Poppery II is ideal) and have graduated to a small coffee roaster. My favorite resource for everything from roasting instructions to green coffee beans is http://www.u-roast-em.com/. Owner Jim Cameron has a wealth of knowledge and is anxious to share.
      You won’t believe how easy it is to roast coffee. And enjoyable, too. I roast only one-week’s worth at a time—about twenty minutes. Green coffee beans have an indefinite, useful shelf life of at least a year, and probably two or longer. But I’ll never know. Coffee beans just don’t last that long around my house!
