    • LOL.   Mech , I'm glad  I'm not the only one to  post in the wrong thread in a group  and cause a  lot of "Huh"s?. My  guess would be  a bad diode too.  I  couldn't find a schematic  on that quads electronics ,on a  quick search ,  but if a  VOM  is not  handy  he could try  disconnecting the voltage regulator and  then  see if it  still has the drain down  problem  after a few days sitting.
    • Hi. You can't fit a regular clear plastic filter to a fuel injected bike.. They have about forty pounds of pressure in the lines and it could burst and start a fire. I'd be suspecting an electronic fault. That time related aspect sounds like an electronic component getting hot then failing, then cooling and starting to work again. I'd suspect cdi or ecu. That said, there was a case in here the other week that turned out to be a tight valve clearance. Checking the valve clearance would be a good idea. And, in all problem diagnosis they always say as the first step.. do a standard tune and check everything is to specs.. So fuel pressure, voltage, aircleaner, tank vents ..  It's boring but you really want to know everything's right before you start fitting parts..
    • Dang... Posted in the wrong thread..  Problems with a slow connection.. Haha So is the battery going flat while the bikes parked up, or after two days of being used.. I'd be checking the charging system's working.  Put a multi meter on Dc on the battery while it's running and see it's got at least thirteen volts. Then I'd put the gauge to AC and check the power for ripple.. if it has a faulty diode in the regulator there will be some AC showing, and a dud diode could be what's draining the battery.
    • Hi. You can't fit a normal clear plastic fuel filter to a fuel injected system, they have about forty pounds of pressure in the line. I'd be suspecting that your problem's an electrical fault, and an electronic fault to be exact.. So cdi unit or something in the ecu.  The fact it takes a certain amount of time, rather than load or throttle to cause it is what makes me think that, and the fact it takes a few minutes to cool down again. Overheating electronics do that. That said, there was a case in here the other week with similar symptoms and it turned out to be tight valve clearances.. as the engine gets hot the valves must have been loosing their clearance and holding a valve open.. Perhaps check them before trying a new cdi or ecu... 
    • Hello to everyone, I just joined tonite so I guess Im about as new as one can be! lol I have a small farm in north central Missouri, I have a couple Yamaha quads, an 02 Grizzly 660 and an 87 Big Bear 400. From what I have seen thus far this seems to be a friendly, knowledgable, and helpful group of people and Im excited to be a member. I hope I will be able to contribute as well. It would be wonderful to get together with other members to go riding someday, if at all possible. Best wishes to all!
