1999 400ex
k&n and White Bros E series with no baffle
Not* origional owner
I have been fighting with this thing for quite some time now, always seemed to be running dog rich. My first attempt at resolving my issues I found the previous owner had a 165 main in her. I thought that was really too big so I downsized to a 152 ( I think I was suggested that size from somone on this forum). That was a no go, backfired like crazy and loss of power, so that way lean as piss I assume. I threw in a 155 for the time being and called er good for the moment. It does not seem like she has the power I felt with the 165 in. But with both the 165 and 155 had my plug fouled, even after messing with the air screw.
(on the trails people behind me could smell unburnt fuel outa my tail pipe)
What I just realized:
In my Claymer it directs the needle to be adjusted to 3 down from the top which is the stock position, so I had done that while messing with my jets. What I had just realized was in the Clymer manual the Needle in there has 5 slots, and mine has 6 slots... Is this an aftermarket needle posibbly? And if so do you think I need to try 2 from the top instead to lean it out a bit?
Im not a carb expert by any means, which is why I am asking help from you guys
hopfully somone will throw in their 5psi (2cents)<<-Im a turbo guy
Thanks
in advance!
