My buddie has a 04 yfz 450 that has been giving us some issues. Moastly me because I wrench it for him. So here is the issue.....
One day it was running and he said it started cutting in and out and then shut off. So I told him to cleen the carb out figuring the float was jamed or somthin. So I go over to pick his quad up for the practice the next day. Put the carb on the quad.
Heres wher it gets tricky...
quad starts up with good batery charge. But then dies just as before
Batery looses chage fast so we bump start it.
Quad dies, pops, backires any thing below like 3k. headlights Are on th whole time btw.
I figure the stator or flywheels is gummed up at this point. I take the stator cover off and the flywheel was slugy, So I cleened it well.
once together we bump start it and it does the same exact thing.
So at this point im somewhat stumped. So I hook jumper cables from his quad to a car batery.
Quad starts on its own but agin wont run anything below 3k.
So I say "skrew this pos im going to eat"
Eat dinner......
Go back to quad, this time with kids dad also helping a hand.
We disconnected the rectifyer (sp) or voltage regulator thing.
Put the jumper cables on it. quad sarts up, blows both headlight bulbs instatly and runs MINT!!
Took jumper cables off quad and it runs good, idles, reves all good.
But quad seems not to be making any power to charge the batery, However there IS power running to the burnt headlight bulbs.
Im stumed at this point. But it runs for however long the batery will last. So we are running it. let me know what you think it is.
